How to create a rect from a size? - swift

Ultimately, I'm trying to retrieve the contentSize of my dynamic UIScrollView.
I'm doing this with this loop :
var contentRect = CGRectZero
for view: UIView in self.scrollView.subviews {
var size : CGSize = (view.text?.sizeWithAttributes([NSFontAttributeName: UIFont.systemFontOfSize(14.0)]))
contentRect = CGRectUnion( contentRect, CGRectMake(size) )
}
scrollView.contentSize = contentRect
The body of the loop is syntactically incorrect though. This is because you can't make a CGRectMake with the variable size.
Would anyone know how I can properly create this shape? Is there a better way to refactor this code to make it more elegant?

You need to add x and y coordinates for it to work. Should be something like this:
var contentRect = CGRectZero
for view: UIView in self.scrollView.subviews {
var size : CGSize = (view.text?.sizeWithAttributes([NSFontAttributeName: UIFont.systemFontOfSize(14.0)]))
let rect = CGRectMake(0, 0, size.width, size.height)
contentRect = CGRectUnion( contentRect, rect )
}
scrollView.contentSize = contentRect

Capture screen without spaces?

I have a few png's on a view in which I capture to an image :
let rect: CGRect = self.frame
UIGraphicsBeginImageContextWithOptions(rect.size, false, 0.0);
let context: CGContext = UIGraphicsGetCurrentContext()!
self.layer.render(in: context)
let img: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()
Problem is, that I want to get a final png size as the size of the content on the view, and not as a constant rect size rect.size .
So if the lower content start at 50px and max content ends at 200px, the height of my new png will be 150.
You should iterate through your views to detect the boundaries of your content.
You can calculate the frame manually:
var minX = view.frame.origin.x + view.frame.size.width
var minY = view.frame.origin.y + view.frame.size.height
var maxX = 0
var maxY = 0
for subview in self.subviews {
minX = min(minX, subview.frame.origin.x)
minY = min(minY, subview.frame.origin.y)
maxX = max(maxX, subview.frame.origin.x + subview.frame.size.width)
maxY = max(maxY, subview.frame.origin.y + subview.frame.size.height)
}
var newPngRect = CGRect(x: minX, y: minY, width: maxX-minX, height: maxY-minY)
UIGraphicsBeginImageContextWithOptions(newPngRect!, false, 0.0)
Or determine the union of your subviews:
var newPngRect = CGRect.zero
for subview in subviews {
baseRect = baseRect.union(subview.frame)
}
UIGraphicsBeginImageContextWithOptions(newPngRect, false, 0.0)
Consider that self.subviews could be replaced for yourContentView.subviews in case its needed.
Create a single view that contains all of the subviews for which you want to screenshot (a containerView).
Use auto layout to layout all of its subviews however you want.
When you're ready to screenshot the view, use:
UIGraphicsBeginImageContextWithOptions(containerView.frame.size, false, 0.0);
let context: CGContext = UIGraphicsGetCurrentContext()!
containerView.layer.render(in: context)
let img: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()

Why does the contentSize of my UIScrollView not change?

I'm trying to make a UIScrollView that contains different settings. Although I connected the UIScrollView to my ViewController and programmatically changed the content size, the UIScrollView only scrolls horizontally, which is not the way it is supposed to (it's supposed to only scroll vertically). This is what I use to define the UIScrollView content size :
self.scrollView.contentSize = CGSize(width: self.view.bounds.width, height: 1400)
Another important thing is that I set the View controller simulated size to freeform with a width of 375 and an height of 1000.
I've been trying to figure out for a while and I can't find what I'm doing wrong. If you have any idea what could this be due to I would really appreciate it.
Thanks in advance.
func viewDidLayoutSubviews() {
self.scrollView.contentSize = CGSize(width: self.view.bounds.width, height: 1400)
}
UIScrollview contentSize dynamically(depending subviews frame)
Swift:
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
DispatchQueue.main.async {
var contentRect = CGRect.zero
for view in self.scrollView.subviews {
contentRect = contentRect.union(view.frame)
}
self.scrollView.contentSize = contentRect.size
}
}
Objective C:
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
dispatch_async(dispatch_get_main_queue(), ^ {
CGRect contentRect = CGRectZero;
for(UIView *view in scrollView.subviews)
contentRect = CGRectUnion(contentRect,view.frame);
scrollView.contentSize = contentRect.size;
});
}

Can't fit UIImage inside UIScrollview

I'm using this code to pick an image from gallery and fit it inside a UIScrollView:
let imageView = UIImageView(image: inputImageDelegate!)
imageView.frame = CGRect(x: 0, y: 0, width: contentView.frame.width, height: contentView.frame.height)
imageView.contentMode = UIViewContentMode.ScaleAspectFill
inputImage = imageView
contentView.addSubview(imageView)
self.scrollView.minimumZoomScale = 0.5
self.scrollView.maximumZoomScale = 6.0
self.scrollView.contentSize = self.inputImage.frame.size
self.scrollView.delegate = self
self.scrollView.zoomScale = 1
imageView.sizeToFit()
Result:
I want to make image's width equal to the screen width after loading (user can scale it up and down). Neither of self.scrollView.zoomScale = 1 nor imageView.sizeToFit() worked.
I'll assume you have your scroll view connected to an IBOutlet like this:
#IBOutlet weak var scrollView: UIScrollView!
You should set the frame of the UIImageView based on the UIScrollView's contentSize property.
let imageView = UIImageView(image: inputImageDelegate!)
let contentSize = self.scrollView.contentSize // convenience
imageView.frame = CGRect(x: 0, y: 0, width: contentSize.width, height: contentSize.height)

How to draw vertical text in UILabel

I'm currently working on drawing vertical Chinese text in a label. Here's what I am trying to achieve, albeit with Chinese Characters:
I've been planning to draw each character, rotate each character 90 degrees to the left, then rotating the entire label via affine transformations to get the final result. However, it feels awfully complicated. Is there an easier way to draw the text without complicated CoreGraphics magic that I'm missing?
Well, You can do like below:
labelObject.numberOfLines = 0;
labelObject.lineBreakMode = NSLineBreakByCharWrapping;
and setFrame with -- height:100, width:20 It will work fine..
It works
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 30, 100)];
lbl.transform = CGAffineTransformMakeRotation((M_PI)/2);
Tried the method offered by Simha.IC but it didn't work well for me. Some characters are thinner than others and get placed two on a line. E.g.
W
ai
ti
n
g
The solution for me was to create a method that transforms the string itself into a multiline text by adding \n after each character. Here's the method:
- (NSString *)transformStringToVertical:(NSString *)originalString
{
NSMutableString *mutableString = [NSMutableString stringWithString:originalString];
NSRange stringRange = [mutableString rangeOfString:mutableString];
for (int i = 1; i < stringRange.length*2 - 2; i+=2)
{
[mutableString insertString:#"\n" atIndex:i];
}
return mutableString;
}
Then you just setup the label like this:
label.text = [self transformStringToVertical:myString];
CGRect labelFrame = label.frame;
labelFrame.size.width = label.font.pointSize;
labelFrame.size.height = label.font.lineHeight * myString.length;
label.frame = labelFrame;
Enjoy!
If you would like to rotate the whole label (including characters), you can do so as follows:
First add the QuartzCore library to your project.
Create a label:
UILabel* label = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 300.0, 30.0)];
[label setText:#"Label Text"];
Rotate the label:
[label setTransform:CGAffineTransformMakeRotation(-M_PI / 2)];
Depending on how you'd like to position the label you may need to set the anchor point. This sets the point around which a rotation occurs. Eg:
[label.layer setAnchorPoint:CGPointMake(0.0, 1.0)];
This is another way to draw vertical text, by subclassing UILabel. But it is some kind different of what the question want.
Objective-C
#implementation MyVerticalLabel
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect {
// Drawing code
CGContextRef context = UIGraphicsGetCurrentContext();
CGAffineTransform transform = CGAffineTransformMakeRotation(-M_PI_2);
CGContextConcatCTM(context, transform);
CGContextTranslateCTM(context, -rect.size.height, 0);
CGRect newRect = CGRectApplyAffineTransform(rect, transform);
newRect.origin = CGPointZero;
NSMutableParagraphStyle *textStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
textStyle.lineBreakMode = self.lineBreakMode;
textStyle.alignment = self.textAlignment;
NSDictionary *attributeDict =
#{
NSFontAttributeName : self.font,
NSForegroundColorAttributeName : self.textColor,
NSParagraphStyleAttributeName : textStyle,
};
[self.text drawInRect:newRect withAttributes:attributeDict];
}
#end
A sample image is following:
Swift
It can put on the storyboard, and watch the result directly. Like the image, it's frame will contain the vertical text. And text attributes, like textAlignment, font, work well too.
#IBDesignable
class MyVerticalLabel: UILabel {
override func drawRect(rect: CGRect) {
guard let text = self.text else {
return
}
// Drawing code
let context = UIGraphicsGetCurrentContext()
let transform = CGAffineTransformMakeRotation( CGFloat(-M_PI_2))
CGContextConcatCTM(context, transform)
CGContextTranslateCTM(context, -rect.size.height, 0)
var newRect = CGRectApplyAffineTransform(rect, transform)
newRect.origin = CGPointZero
let textStyle = NSMutableParagraphStyle.defaultParagraphStyle().mutableCopy() as! NSMutableParagraphStyle
textStyle.lineBreakMode = self.lineBreakMode
textStyle.alignment = self.textAlignment
let attributeDict: [String:AnyObject] = [
NSFontAttributeName: self.font,
NSForegroundColorAttributeName: self.textColor,
NSParagraphStyleAttributeName: textStyle,
]
let nsStr = text as NSString
nsStr.drawInRect(newRect, withAttributes: attributeDict)
}
}
Swift 4
override func draw(_ rect: CGRect) {
guard let text = self.text else {
return
}
// Drawing code
if let context = UIGraphicsGetCurrentContext() {
let transform = CGAffineTransform( rotationAngle: CGFloat(-Double.pi/2))
context.concatenate(transform)
context.translateBy(x: -rect.size.height, y: 0)
var newRect = rect.applying(transform)
newRect.origin = CGPoint.zero
let textStyle = NSMutableParagraphStyle.default.mutableCopy() as! NSMutableParagraphStyle
textStyle.lineBreakMode = self.lineBreakMode
textStyle.alignment = self.textAlignment
let attributeDict: [NSAttributedStringKey: AnyObject] = [NSAttributedStringKey.font: self.font, NSAttributedStringKey.foregroundColor: self.textColor, NSAttributedStringKey.paragraphStyle: textStyle]
let nsStr = text as NSString
nsStr.draw(in: newRect, withAttributes: attributeDict)
}
}
Swift 5
More easy way with CGAffineTransform
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var verticalText: UILabel
override func viewDidLoad() {
verticalText.transform = CGAffineTransform(rotationAngle:CGFloat.pi/2)
}
}
import UIKit
class VerticalLabel : UILabel {
private var _text : String? = nil
override var text : String? {
get {
return _text
}
set {
self.numberOfLines = 0
self.textAlignment = .center
self.lineBreakMode = .byWordWrapping
_text = newValue
if let t = _text {
var s = ""
for c in t {
s += "\(c)\n"
}
super.text = s
}
}
}
}

How do I auto size a UIScrollView to fit its content

Is there a way to make a UIScrollView auto-adjust to the height (or width) of the content it's scrolling?
Something like:
[scrollView setContentSize:(CGSizeMake(320, content.height))];
The best method I've ever come across to update the content size of a UIScrollView based on its contained subviews:
Objective-C
CGRect contentRect = CGRectZero;
for (UIView *view in self.scrollView.subviews) {
contentRect = CGRectUnion(contentRect, view.frame);
}
self.scrollView.contentSize = contentRect.size;
Swift
let contentRect: CGRect = scrollView.subviews.reduce(into: .zero) { rect, view in
rect = rect.union(view.frame)
}
scrollView.contentSize = contentRect.size
UIScrollView doesn't know the height of its content automatically. You must calculate the height and width for yourself
Do it with something like
CGFloat scrollViewHeight = 0.0f;
for (UIView* view in scrollView.subviews)
{
scrollViewHeight += view.frame.size.height;
}
[scrollView setContentSize:(CGSizeMake(320, scrollViewHeight))];
But this only work if the views are one below the other. If you have a view next to each other you only have to add the height of one if you don't want to set the content of the scroller larger than it really is.
Solution if you're using auto layout:
Set translatesAutoresizingMaskIntoConstraints to NO on all views involved.
Position and size your scroll view with constraints external to the scroll view.
Use constraints to lay out the subviews within the scroll view, being sure that the constraints tie to all four edges of the scroll view and do not rely on the scroll view to get their size.

I added this to Espuz and JCC's answer. It uses the y position of the subviews and doesn't include the scroll bars. Edit Uses the bottom of the lowest sub view that is visible.
+ (CGFloat) bottomOfLowestContent:(UIView*) view
{
CGFloat lowestPoint = 0.0;
BOOL restoreHorizontal = NO;
BOOL restoreVertical = NO;
if ([view respondsToSelector:#selector(setShowsHorizontalScrollIndicator:)] && [view respondsToSelector:#selector(setShowsVerticalScrollIndicator:)])
{
if ([(UIScrollView*)view showsHorizontalScrollIndicator])
{
restoreHorizontal = YES;
[(UIScrollView*)view setShowsHorizontalScrollIndicator:NO];
}
if ([(UIScrollView*)view showsVerticalScrollIndicator])
{
restoreVertical = YES;
[(UIScrollView*)view setShowsVerticalScrollIndicator:NO];
}
}
for (UIView *subView in view.subviews)
{
if (!subView.hidden)
{
CGFloat maxY = CGRectGetMaxY(subView.frame);
if (maxY > lowestPoint)
{
lowestPoint = maxY;
}
}
}
if ([view respondsToSelector:#selector(setShowsHorizontalScrollIndicator:)] && [view respondsToSelector:#selector(setShowsVerticalScrollIndicator:)])
{
if (restoreHorizontal)
{
[(UIScrollView*)view setShowsHorizontalScrollIndicator:YES];
}
if (restoreVertical)
{
[(UIScrollView*)view setShowsVerticalScrollIndicator:YES];
}
}
return lowestPoint;
}
Here is the accepted answer in swift for anyone who is too lazy to convert it :)
var contentRect = CGRectZero
for view in self.scrollView.subviews {
contentRect = CGRectUnion(contentRect, view.frame)
}
self.scrollView.contentSize = contentRect.size
Here's a Swift 3 adaptation of #leviatan's answer :
EXTENSION
import UIKit
extension UIScrollView {
func resizeScrollViewContentSize() {
var contentRect = CGRect.zero
for view in self.subviews {
contentRect = contentRect.union(view.frame)
}
self.contentSize = contentRect.size
}
}
USAGE
scrollView.resizeScrollViewContentSize()
Very easy to use !
Following extension would be helpful in Swift.
extension UIScrollView{
func setContentViewSize(offset:CGFloat = 0.0) {
// dont show scroll indicators
showsHorizontalScrollIndicator = false
showsVerticalScrollIndicator = false
var maxHeight : CGFloat = 0
for view in subviews {
if view.isHidden {
continue
}
let newHeight = view.frame.origin.y + view.frame.height
if newHeight > maxHeight {
maxHeight = newHeight
}
}
// set content size
contentSize = CGSize(width: contentSize.width, height: maxHeight + offset)
// show scroll indicators
showsHorizontalScrollIndicator = true
showsVerticalScrollIndicator = true
}
}
Logic is the same with the given answers. However, It omits hidden views within UIScrollView and calculation is performed after scroll indicators set hidden.
Also, there is an optional function parameter and you're able to add an offset value by passing parameter to function.
Great & best solution from #leviathan. Just translating to swift using FP (functional programming) approach.
self.scrollView.contentSize = self.scrollView.subviews.reduce(CGRect(), {
CGRectUnion($0, $1.frame)
}.size
You can get height of the content inside UIScrollView by calculate which child "reaches furthers". To calculate this you have to take in consideration origin Y (start) and item height.
float maxHeight = 0;
for (UIView *child in scrollView.subviews) {
float childHeight = child.frame.origin.y + child.frame.size.height;
//if child spans more than current maxHeight then make it a new maxHeight
if (childHeight > maxHeight)
maxHeight = childHeight;
}
//set content size
[scrollView setContentSize:(CGSizeMake(320, maxHeight))];
By doing things this way items (subviews) don't have to be stacked directly one under another.
I came up with another solution based on #emenegro's solution
NSInteger maxY = 0;
for (UIView* subview in scrollView.subviews)
{
if (CGRectGetMaxY(subview.frame) > maxY)
{
maxY = CGRectGetMaxY(subview.frame);
}
}
maxY += 10;
[scrollView setContentSize:CGSizeMake(scrollView.frame.size.width, maxY)];
Basically, we figure out which element is furthest down in the view and adds a 10px padding to the bottom
Or just do:
int y = CGRectGetMaxY(((UIView*)[_scrollView.subviews lastObject]).frame); [_scrollView setContentSize:(CGSizeMake(CGRectGetWidth(_scrollView.frame), y))];
(This solution was added by me as a comment in this page. After getting 19 up-votes for this comment, I've decided to add this solution as a formal answer for the benefit of the community!)
Because a scrollView can have other scrollViews or different inDepth subViews tree, run in depth recursively is preferable.
Swift 2
extension UIScrollView {
//it will block the mainThread
func recalculateVerticalContentSize_synchronous () {
let unionCalculatedTotalRect = recursiveUnionInDepthFor(self)
self.contentSize = CGRectMake(0, 0, self.frame.width, unionCalculatedTotalRect.height).size;
}
private func recursiveUnionInDepthFor (view: UIView) -> CGRect {
var totalRect = CGRectZero
//calculate recursevly for every subView
for subView in view.subviews {
totalRect = CGRectUnion(totalRect, recursiveUnionInDepthFor(subView))
}
//return the totalCalculated for all in depth subViews.
return CGRectUnion(totalRect, view.frame)
}
}
Usage
scrollView.recalculateVerticalContentSize_synchronous()
For swift4 using reduce:
self.scrollView.contentSize = self.scrollView.subviews.reduce(CGRect.zero, {
return $0.union($1.frame)
}).size
The size depends on the content loaded inside of it, and the clipping options. If its a textview, then it also depends on the wrapping, how many lines of text, the font size, and so on and on. Nearly impossible for you to compute yourself. The good news is, it is computed after the view is loaded and in the viewWillAppear. Before that, it's all unknown and and content size will be the same as frame size. But, in the viewWillAppear method and after (such as the viewDidAppear) the content size will be the actual.
Wrapping Richy's code I created a custom UIScrollView class that automates
content resizing completely!
SBScrollView.h
#interface SBScrollView : UIScrollView
#end
SBScrollView.m:
#implementation SBScrollView
- (void) layoutSubviews
{
CGFloat scrollViewHeight = 0.0f;
self.showsHorizontalScrollIndicator = NO;
self.showsVerticalScrollIndicator = NO;
for (UIView* view in self.subviews)
{
if (!view.hidden)
{
CGFloat y = view.frame.origin.y;
CGFloat h = view.frame.size.height;
if (y + h > scrollViewHeight)
{
scrollViewHeight = h + y;
}
}
}
self.showsHorizontalScrollIndicator = YES;
self.showsVerticalScrollIndicator = YES;
[self setContentSize:(CGSizeMake(self.frame.size.width, scrollViewHeight))];
}
#end
How to use:
Simply import the .h file to your view controller and
declare a SBScrollView instance instead of the normal UIScrollView one.
why not single line of code??
_yourScrollView.contentSize = CGSizeMake(0, _lastView.frame.origin.y + _lastView.frame.size.height);
I created a subclass of ScrollView to handle the intrinsicContentSize and it worked perfectly for me
public final class ContentSizedScrollView: UIScrollView {
override public var contentSize: CGSize {
didSet {
invalidateIntrinsicContentSize()
}
}
override public var intrinsicContentSize: CGSize {
layoutIfNeeded()
return self.contentSize
}
}
Now you can create a scrollview with this class and set constraints on all sides
Make sure that the subviews are tied up to all fours edges of the scrollView
it depends on the content really : content.frame.height might give you what you want ? Depends if content is a single thing, or a collection of things.
I also found leviathan's answer to work the best. However, it was calculating a strange height. When looping through the subviews, if the scrollview is set to show scroll indicators, those will be in the array of subviews. In this case, the solution is to temporarily disable the scroll indicators before looping, then re-establish their previous visibility setting.
-(void)adjustContentSizeToFit is a public method on a custom subclass of UIScrollView.
-(void)awakeFromNib {
dispatch_async(dispatch_get_main_queue(), ^{
[self adjustContentSizeToFit];
});
}
-(void)adjustContentSizeToFit {
BOOL showsVerticalScrollIndicator = self.showsVerticalScrollIndicator;
BOOL showsHorizontalScrollIndicator = self.showsHorizontalScrollIndicator;
self.showsVerticalScrollIndicator = NO;
self.showsHorizontalScrollIndicator = NO;
CGRect contentRect = CGRectZero;
for (UIView *view in self.subviews) {
contentRect = CGRectUnion(contentRect, view.frame);
}
self.contentSize = contentRect.size;
self.showsVerticalScrollIndicator = showsVerticalScrollIndicator;
self.showsHorizontalScrollIndicator = showsHorizontalScrollIndicator;
}
I think this can be a neat way of updating UIScrollView's content view size.
extension UIScrollView {
func updateContentViewSize() {
var newHeight: CGFloat = 0
for view in subviews {
let ref = view.frame.origin.y + view.frame.height
if ref > newHeight {
newHeight = ref
}
}
let oldSize = contentSize
let newSize = CGSize(width: oldSize.width, height: newHeight + 20)
contentSize = newSize
}
}
Set dynamic content size like this.
self.scroll_view.contentSize = CGSizeMake(screen_width,CGRectGetMaxY(self.controlname.frame)+20);
import UIKit
class DynamicSizeScrollView: UIScrollView {
var maxHeight: CGFloat = UIScreen.main.bounds.size.height
var maxWidth: CGFloat = UIScreen.main.bounds.size.width
override func layoutSubviews() {
super.layoutSubviews()
if !__CGSizeEqualToSize(bounds.size,self.intrinsicContentSize){
self.invalidateIntrinsicContentSize()
}
}
override var intrinsicContentSize: CGSize {
let height = min(contentSize.height, maxHeight)
let width = min(contentSize.height, maxWidth)
return CGSize(width: width, height: height)
}
}
If you using Auto layout, just set the border element's edge equal to your scroll view.
For example, I wanna my horizontal scroll view auto fit my horizontal contents:
Swift
let bottomConstrint = NSLayoutConstraint.init(item: (bottommost UI element),
attribute: .bottom,
relatedBy: .equal,
toItem: (your UIScrollView),
attribute: .bottom,
multiplier: 1.0,
constant: 0)
bottomConstrint.isActive = true
If you using Snapkit like me, just:
scrollView.addSubview( (bottommost element) )
(bottommost element).snp.makeConstraints { make in
/*other constraints*/
make.bottom.equalToSuperview()
}
I would create a subclass of UIScrollView with the following:
class ContentSizedScrollView: UIScrollView {
override var contentSize:CGSize {
didSet {
invalidateIntrinsicContentSize()
}
}
override var intrinsicContentSize: CGSize {
layoutIfNeeded()
return CGSize(width: UIView.noIntrinsicMetric, height: contentSize.height)
}
}
This will resize automatically based on the height of the content.
class ContentSizedScrollView: UIScrollView {
override var contentSize:CGSize {
didSet {
invalidateIntrinsicContentSize()
}
}
override var intrinsicContentSize: CGSize {
layoutIfNeeded()
return CGSize(width: UIView.noIntrinsicMetric, height: contentSize.height)
}
}
// In UIViewController
import SnapKit
...
var scrollView: ContentSizedScrollView!
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
scrollView.contentSize = .init(width: view.bounds.width, height: stackView.bounds.height)
}
// Here some example of content composing inside of UIStackView
func setupContent() {
scrollView = ContentSizedScrollView()
blockView.addSubview(scrollView)
scrollView.snp.makeConstraints { make in
make.top.equalTo(19)
make.left.equalToSuperview()
make.right.equalToSuperview()
make.bottom.equalTo(-20)
}
scrollView.contentInset = .init(top: 0, left: 0, bottom: 26, right: 0)
scrollView.showsVerticalScrollIndicator = false
scrollView.clipsToBounds = true
scrollView.layer.cornerRadius = blockView.layer.cornerRadius / 2
stackView = UIStackView()
scrollView.addSubview(stackView)
stackView.snp.makeConstraints { make in
make.top.equalToSuperview()
make.centerX.equalToSuperview()
make.width.equalToSuperview().offset(-10)
}
stackView.axis = .vertical
stackView.alignment = .center
textTitleLabel = Label()
stackView.addArrangedSubview(textTitleLabel)
textTitleLabel.snp.makeConstraints { make in
make.width.equalToSuperview().offset(-30)
}
textTitleLabel.font = UIFont.systemFont(ofSize: 20, weight: .bold)
textTitleLabel.textColor = Color.Blue.oxfordBlue
textTitleLabel.textAlignment = .center
textTitleLabel.numberOfLines = 0
stackView.setCustomSpacing(10, after: textTitleLabel)
}
