i am trying to place the image below the text i add
class SolicitudViewController: BaseViewController {
lazy var imagePrincipal : UIImageView = {
let imageView = UIImageView()
imageView.image = UIImage(named: "diseño")
imageView.contentMode = .scaleAspectFit
imageView.translatesAutoresizingMaskIntoConstraints = false
//imageView.heightAnchor.constraint(equalToConstant: 50).isActive = true
//imageView.bottomAnchor.constraint(equalToConstant: 100).isActive = true
return imageView
}()
lazy var stackView : UIStackView = {
let stack = UIStackView()
stack.axis = .vertical
stack.distribution = .fill
stack.translatesAutoresizingMaskIntoConstraints = false
stack.addArrangedSubview(imagePrincipal)
//stack.addArrangedSubview(lblsubTitulo)
//stack.addArrangedSubview(lineView)
stack.addArrangedSubview(imageEvaluando2)
stack.addArrangedSubview(imageEvaluando3)
return stack
}()
lazy var scrollView : UIScrollView = {
let scrollView = UIScrollView()
scrollView.translatesAutoresizingMaskIntoConstraints = false
scrollView.addSubview(stackView)
return scrollView
}()
override func viewDidLoad() {
super.viewDidLoad()
setSubtitle(subtitle: "test View")
}
I have tried to use this: stack.setCustomSpacing(30, after: imagePrincipal) but it positions the image on top, I want the image to be below the text
I have Stackview inside a custom UICollectionViewCell, which has an image and label.
private lazy var imageView: UIImageView = {
let imageView: UIImageView = UIImageView()
imageView.clipsToBounds = true
imageView.contentMode = .scaleAspectFill
return imageView
}()
private lazy var textLabel: UILabel = {
let label: UILabel = UILabel()
label.font = MUIFont.tiny
label.numberOfLines = 3
return label
}()
init() {
let stackView: UIStackView = UIStackview(arrangedSubViews:[imageView, textLabel])
stackView.axis = .vertical
contentview.addSubView(stackView)
// add all four side constraints.
}
struct Model: Codable {
let text: String?
let imageURL: String
}
func setData(model: Model) {
if let text: String = model.text {
label.isHideen = false
label.text = text
}
else {
label.isHidden = true
}
imageView.setImageWithString(model.imageURL)
Now the problem is I have 1000's of data so for reusable cells which has only image is not coming full still label space left.It is happening only for re-usable cells.
Can someone explain how can we solve it.
I've spent almost a couple of hours to figure it out. However, it did not happen and finally, I had to come here. Two things are required to be achieved:
Firstly I'd like to have a spontaneous corner radius at the top (which is basically TopRight & TopLeft) of UITabbar.
Secondly, I'd like to have a shadow above those corner radius(shown in below image).
Please have a look at below image
Let me know if anything further required from my side, I'll surely provide that.
Any help will be appreciated.

One more little question arose here along, suppose, Even if, However, we were able to accomplish this, Would Apple review team accept the application?
I'm being little nervous and curious about it.

You can achieve this with some custom view with a custom tab bar controller. You can customize the colors and shadows by editing only the custom views.
Custom Tab Bar Controller
import UIKit
class MainTabBarController: UITabBarController{
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
tabBar.backgroundImage = UIImage.from(color: .clear)
tabBar.shadowImage = UIImage()
let tabbarBackgroundView = RoundShadowView(frame: tabBar.frame)
tabbarBackgroundView.cornerRadius = 25
tabbarBackgroundView.backgroundColor = .white
tabbarBackgroundView.frame = tabBar.frame
view.addSubview(tabbarBackgroundView)
let fillerView = UIView()
fillerView.frame = tabBar.frame
fillerView.roundCorners([.topLeft, .topRight], radius: 25)
fillerView.backgroundColor = .white
view.addSubview(fillerView)
view.bringSubviewToFront(tabBar)
}
Rounded Shadow View
import UIKit
class RoundShadowView: UIView {
let containerView = UIView()
override init(frame: CGRect) {
super.init(frame: frame)
layoutView()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func layoutView() {
// set the shadow of the view's layer
layer.backgroundColor = UIColor.clear.cgColor
layer.shadowColor = UIColor.black.cgColor
layer.shadowOffset = CGSize(width: 0, height: -8.0)
layer.shadowOpacity = 0.12
layer.shadowRadius = 10.0
containerView.layer.cornerRadius = cornerRadius
containerView.layer.masksToBounds = true
addSubview(containerView)
containerView.translatesAutoresizingMaskIntoConstraints = false
// pin the containerView to the edges to the view
containerView.leadingAnchor.constraint(equalTo: leadingAnchor).isActive = true
containerView.trailingAnchor.constraint(equalTo: trailingAnchor).isActive = true
containerView.topAnchor.constraint(equalTo: topAnchor).isActive = true
containerView.bottomAnchor.constraint(equalTo: bottomAnchor).isActive = true
}
}
UIImage extension
import UIKit
extension UIImage {
static func from(color: UIColor) -> UIImage {
let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
UIGraphicsBeginImageContext(rect.size)
let context = UIGraphicsGetCurrentContext()
context!.setFillColor(color.cgColor)
context!.fill(rect)
let img = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return img!
}
}
To add any radius or shape you can use a UIBezierPath. The example that I put has left and right corners with a radius and you can use more designable personalizations if you want.
#IBDesignable class TabBarWithCorners: UITabBar {
#IBInspectable var color: UIColor?
#IBInspectable var radii: CGFLoat = 15.0
private var shapeLayer: CALayer?
override func draw(_ rect: CGRect) {
addShape()
}
private func addShape() {
let shapeLayer = CAShapeLayer()
shapeLayer.path = createPath()
shapeLayer.strokeColor = UIColor.gray.withAlphaComponent(0.1).cgColor
shapeLayer.fillColor = color?.cgColor ?? UIColor.white.cgColor
shapeLayer.lineWidth = 1
if let oldShapeLayer = self.shapeLayer {
layer.replaceSublayer(oldShapeLayer, with: shapeLayer)
} else {
layer.insertSublayer(shapeLayer, at: 0)
}
self.shapeLayer = shapeLayer
}
private func createPath() -> CGPath {
let path = UIBezierPath(
roundedRect: bounds,
byRoundingCorners: [.topLeft, .topRight],
cornerRadii: CGSize(width: radii, height: 0.0))
return path.cgPath
}
}
Swift 5.3.1, XCode 11+, iOS 14
For using in storyboards:
import UIKit
class CustomTabBar: UITabBar {
override func awakeFromNib() {
super.awakeFromNib()
layer.masksToBounds = true
layer.cornerRadius = 20
layer.maskedCorners = [.layerMinXMinYCorner,.layerMaxXMinYCorner]
}
}
Subclassing UITabBarController then overried viewWillLayoutSubviews()
and add this code .
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
self.tabBar.layer.masksToBounds = true
self.tabBar.layer.cornerRadius = 12 // whatever you want
self.tabBar.layer.maskedCorners = [.layerMinXMinYCorner,.layerMaxXMinYCorner] // only the top right and left corners
}
This will be the result
I'm trying to implement nested stack views in which one stack view is inside another stack view. I've based my code here. My current code is here below.
#IBOutlet weak var verticalStackView: UIStackView!
let blueImageView = UIImageView()
blueImageView.backgroundColor = UIColor.blueColor()
blueImageView.image = UIImage(named: "just some image")
blueImageView.snp_makeConstraints { (make) in
make.height.width.equalTo(34)
}
let greenImageView = UIImageView()
greenImageView.backgroundColor = UIColor.greenColor()
greenImageView.image = UIImage(named: "just some image")
// This is just from SnapKit
greenImageView.snp_makeConstraints { (make) in
make.height.width.equalTo(34)
}
let stackView = UIStackView()
stackView.axis = UILayoutConstraintAxis.Horizontal
stackView.distribution = UIStackViewDistribution.EqualSpacing
stackView.alignment = UIStackViewAlignment.Center
stackView.spacing = 16.0
stackView.addArrangedSubview(blueImageView)
stackView.addArrangedSubview(greenImageView)
stackView.translatesAutoresizingMaskIntoConstraints = false;
// This is just from SnapKit
verticalStackView.snp_makeConstraints { (make) in
make.height.equalTo(70)
}
verticalStackView.addSubview(stackView)
When I tried running it looks this way.
As you can see, the sub stack view stackView is below the parent stack view (verticalStackView) in the hierarchy. But the positioning is off.
I'm quite new with Swift, AutoLayout and StackViews. Anyone that can help point out what I'm missing here?
Thanks!
So I've figured out the solution after some reading..
#IBOutlet weak var verticalStackView: UIStackView!
let blueImageView = UIImageView()
blueImageView.backgroundColor = UIColor.blueColor()
blueImageView.image = UIImage(named: "buttonFollowCheckGreen")
blueImageView.snp_makeConstraints { (make) in
make.height.width.equalTo(34)
}
let greenImageView = UIImageView()
greenImageView.backgroundColor = UIColor.greenColor()
greenImageView.image = UIImage(named: "buttonFollowCheckGreen")
greenImageView.snp_makeConstraints { (make) in
make.height.width.equalTo(34)
}
let firstLineStackView = UIStackView()
firstLineStackView.axis = UILayoutConstraintAxis.Horizontal
firstLineStackView.distribution = UIStackViewDistribution.Fill
firstLineStackView.alignment = UIStackViewAlignment.Center
firstLineStackView.spacing = 8.0
firstLineStackView.addArrangedSubview(blueImageView)
firstLineStackView.addArrangedSubview(greenImageView)
firstLineStackView.translatesAutoresizingMaskIntoConstraints = false;
let redImageView = UIImageView()
redImageView.backgroundColor = UIColor.redColor()
redImageView.image = UIImage(named: "buttonFollowCheckGreen")
redImageView.snp_makeConstraints { (make) in
make.height.width.equalTo(34)
}
verticalStackView.addArrangedSubview(firstLineStackView)
I just had to use addArrangedSubview instead of addSubview and let Auto layout do the rest. Just to fix the positioning and size of the image views, I've also modified the alignment of the verticalStackView from fill to leading.
greenImageView.heightAnchor.constraint(equalToConstant: 34).isActive = true
greenImageView.widthAnchor.constraint(equalToConstant: 34).isActive = true
and it will be solved
I have a working ViewController with working UIBlurEffect. Here is my code:
#IBOutlet weak var nameLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let blurEffect = UIBlurEffect(style: .Light)
let blurView = UIVisualEffectView(effect: blurEffect)
blurView.frame = self.view.frame
blurView.setTranslatesAutoresizingMaskIntoConstraints(false)
self.view.insertSubview(blurView, atIndex: 0)
}
Now I would like to add a UIVibranyEffect to the nameLabel.
How to add UIVibrancyEffect programatically to an existing UILabel?
You need to instantiate an UIVisualEffectView and add whatever you want to be vibrant inside it. For example:
// Blur Effect
let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.Dark)
let blurEffectView = UIVisualEffectView(effect: blurEffect)
blurEffectView.frame = view.bounds
view.addSubview(blurEffectView)
// Vibrancy Effect
let vibrancyEffect = UIVibrancyEffect(forBlurEffect: blurEffect)
let vibrancyEffectView = UIVisualEffectView(effect: vibrancyEffect)
vibrancyEffectView.frame = view.bounds
// Label for vibrant text
let vibrantLabel = UILabel()
vibrantLabel.text = "Vibrant"
// Add label to the vibrancy view
vibrancyEffectView.contentView.addSubview(vibrantLabel)
// Add the vibrancy view to the blur view
blurEffectView.contentView.addSubview(vibrancyEffectView)
