Due to UIProgressHUD need to access private api,
so I hope to construct an UIView with round corner and white border.
I know to make the corner round is:
view.layer.cornerRadius = 5;
But how to make the uiview has round corner and white border at the same time?
Welcome any comment
Thanks
interdev
Using the same layer object:
view.layer.borderWidth = 1;
view.layer.borderColor = [[UIColor whiteColor] CGColor];
Sometimes corner radius with white border does not work properly so I use UIBezierPath and CAShapeLayer.
For make the corner radius
UIBezierPath *maskPath;
maskPath = [UIBezierPath bezierPathWithRoundedRect:self.imageView.bounds byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerTopRight | UIRectCornerBottomLeft | UIRectCornerBottomRight) cornerRadii:CGSizeMake(10.0, 10.0)];
CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = self.view.bounds;
maskLayer.path = maskPath.CGPath;
self.imageView.layer.mask = maskLayer;
For make the border white
CAShapeLayer* borderShape = [CAShapeLayer layer];
borderShape.frame = self.imageView.bounds;
borderShape.path = maskPath.CGPath;
borderShape.strokeColor = [UIColor whiteColor].CGColor;
borderShape.fillColor = nil;
borderShape.lineWidth = 3;
[self.imageView.layer addSublayer:borderShape];
It will work. Hope this help
There are border properties in the layer of the view as well: eg:
view.layer.borderWidth = 1;
view.layer.borderColor = [UIColor redColor].CGColor;
view.layer.cornerRadius = 5;
view.clipsToBounds = YES;
view.layer.borderWidth = 1;
view.layer.borderColor = [UIColor whiteColor].CGColor;
code to get rounded corners and border
#import <QuartzCore/QuartzCore.h>
view.layer.cornerRadius = 10;
view.layer.borderWidth = 1;
view.layer.borderColor = [[UIColor whiteColor] CGColor];
[view.layer setBorderWidth:2];
[view.layer setBorderColor:[[UIColor whiteColor]CGColor]];

I am trying to create glow just around the sides of the rectangle. The rest of the rectangle should be filled clear color. I create a UIView with CGRect of certain size and then -
self.backgroundColor = [UIColor clearColor];
self.layer.borderWidth = 2.0f;
self.layer.borderColor = [UIColor colorWithRed:203/255.0 green:1.0 blue:252/255.0 alpha:1.0f].CGColor;
self.layer.cornerRadius = 5.0f;
int glowSpread = 2;
CGRect glowRect = CGRectMake(self.bounds.origin.x-glowSpread, self.bounds.origin.y-glowSpread, self.bounds.size.width+2*glowSpread, self.bounds.size.height+2*glowSpread);
self.layer.shadowPath = [UIBezierPath bezierPathWithRoundedRect:glowRect cornerRadius:5.0].CGPath;
self.layer.shadowColor = [UIColor colorWithRed:203/255.0 green:1.0 blue:252/255.0 alpha:1.0f].CGColor;
self.layer.shadowOffset = CGSizeMake(0, 0);
self.layer.shadowOpacity = 0.5;
self.layer.shadowRadius = 2.0f;
With the above approach, I get the glow around the side but the whole CGRect gets filled with the shadow color, which I do not want. Any suggestion?
make a more complicated shadow path that isn't enclosed, or just add a sublayer of the color you want.
Hi guys I've creates this box, basically the corner radius isn't working & the stroke doesn't show on the top side of the shape either. Is there anyway to get this working?
UIBezierPath* conPath = [UIBezierPath bezierPath];
[conPath moveToPoint:CGPointMake(conX, conY)];
[conPath addLineToPoint:CGPointMake(conX, conY+50)];
[conPath addLineToPoint:CGPointMake(conX+220, conY+50)];
[conPath addLineToPoint:CGPointMake(conX+220, conY)];
CAShapeLayer* conLayer = [CAShapeLayer layer];
conLayer.path = conPath.CGPath;
conLayer.cornerRadius = 5.0;
UIColor *bg = [UIColor colorWithWhite:1 alpha:0.7];
[conLayer setFillColor:bg.CGColor];
[conLayer setStrokeColor:[UIColor grayColor].CGColor];
[[self layer] addSublayer:conLayer];
I want to apply two types of border on a UIImageView:
One is the border on the layer of the UIImageView.
Second is the border around the layer of the UIImageView.
How can I do this?
Try
#define kBorderWidth 3.0
#define kCornerRadius 8.0
CALayer *borderLayer = [CALayer layer];
CGRect borderFrame = CGRectMake(0, 0, (imageView.frame.size.width), (imageView.frame.size.height));
[borderLayer setBackgroundColor:[[UIColor clearColor] CGColor]];
[borderLayer setFrame:borderFrame];
[borderLayer setCornerRadius:kCornerRadius];
[borderLayer setBorderWidth:kBorderWidth];
[borderLayer setBorderColor:[[UIColor redColor] CGColor]];
[imageView.layer addSublayer:borderLayer];
And don't forget to import QuartzCore/QuartzCore.h
This example will draw a boarder on the layer, but change it's frame slightly to make the border around the layer.
Another way
You must import
#import <QuartzCore/QuartzCore.h>
Then add code for your UIImageView
imgView.clipsToBounds = YES;
imgView.layer.cornerRadius = 8.0;
imgView.layer.borderWidth = 2.0;
imgView.layer.borderColor = [UIColor greenColor].CGColor;
An other way is to add another layer that goes a bit outside of the UIImageView's layer like so :
CALayer * externalBorder = [CALayer layer];
externalBorder.frame = CGRectMake(-1, -1, myView.frame.size.width+2, myView.frame.size.height+2);
externalBorder.borderColor = [UIColor blackColor].CGColor;
externalBorder.borderWidth = 1.0;
[myView.layer addSublayer:externalBorder];
myView.layer.masksToBounds = NO;
Swift 5
Beware when using a UIImageView; masksToBounds = false means the image will spill over
let outsideBorder = CALayer()
outsideBorder.frame = CGRect(x: -1, y: -1, width: myView.frame.size.width+2, height: myView.frame.size.height+2)
outsideBorder.borderColor = UIColor.black.cgColor
outsideBorder.borderWidth = 1.0
myView.layer.addSublayer(outsideBorder)
myView.masksToBounds = false
How to make a half rounded (Top corner rounded) textview or tableview with the borderwidth and borderColor?
This isn't perfect, but you can work from this:
#import <QuartzCore/CoreAnimation.h>
(and also link to QuartzCore.framework in your project), then..
self.textView.layer.borderColor = [UIColor redColor].CGColor;
self.textView.layer.borderWidth = 4.0f;
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.textView.bounds
byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight
cornerRadii:CGSizeMake(7.0, 7.0)];
CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = self.textView.bounds;
maskLayer.path = maskPath.CGPath;
self.textView.layer.mask = maskLayer;
[maskLayer release];
First remove all code that would generate a border (xib or layer.borderWidth) and them use this method below that I created in a UIView Category:
#import "UIView+RoundedCorners.h"
#implementation UIView (RoundedCorners)
#pragma mark - Public
- (void)addBorderWithRoundedCorners:(UIRectCorner)roundedCorners radius:(CGFloat)radius color:(UIColor *)color
{
self.clipsToBounds = NO;
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.bounds byRoundingCorners:roundedCorners cornerRadii:CGSizeMake(radius, radius)];
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = self.bounds;
maskLayer.path = maskPath.CGPath;
maskLayer.lineWidth = 1.0;
maskLayer.strokeColor = color.CGColor;
maskLayer.fillColor = [UIColor clearColor].CGColor;
[self.layer addSublayer:maskLayer];
}
#end
i think use bellow code
[yourTextView.layer setBorderColor: [[UIColor redColor] CGColor]];
[yourTextView.layer setBorderWidth: 1.0];
[yourTextView.layer setCornerRadius:8.0f];
[yourTextView.layer setMasksToBounds:YES];
also use yourTableView insted of yourTextView
I am trying to mask an image so that I can give it only two rounded corners. With the code that I have it just adds the mask in white over the image, but doesn't seem to apply it. What do I need to do different to mask the image corners?
CAShapeLayer *maskLayer = [CAShapeLayer layer];
UIBezierPath *roundedPath = [UIBezierPath bezierPathWithRoundedRect:maskLayer.bounds byRoundingCorners:UIRectCornerTopLeft | UIRectCornerBottomRight cornerRadii:CGSizeMake(16.f, 16.f)];
maskLayer.fillColor = [[UIColor whiteColor] CGColor];
maskLayer.backgroundColor = [[UIColor clearColor] CGColor];
maskLayer.path = [roundedPath CGPath];
// Add mask
self.imageView.layer.mask = maskLayer;
Round two corners in UIView
As mentioned in the above linked question, you probably need to remove the view from the heirarchy before applying its mask.
[self.imageView removeFromSuperview];
self.imageView.layer.mask = maskLayer;
[self.view addSubview:self.imageView];
Also, your maskLayer has no bounds. You need to set it to the frame (or bounds) of the view you're trying to mask.
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = self.imageView.frame;
