I need to stretch image right and left side centre half circle remain as it is. also need half circle in center
I have tried slicing concept and also tried below code
UIImage *image = self.imgBGBottom.image;
CGFloat capWidth = floorf(image.size.width / 2) - 50;
CGFloat capHeight = 0;
UIImage *capImage = [image resizableImageWithCapInsets:
UIEdgeInsetsMake(capHeight, capWidth, capHeight, capWidth)];
[self.imgBGBottom setImage:capImage];
but it is not working for me
Please help me. Thanks in advance.
You are using function, use - (UIImage *)stretchableImageWithLeftCapWidth:(NSInteger)leftCapWidth topCapHeight:(NSInteger)topCapHeight
instead - (UIImage *)resizableImageWithCapInsets:(UIEdgeInsets)capInsets
.
Set top, left cap to stretch your image as described in following code.
Objective-C
UIImage *image = [UIImage imageNamed:@"test"];
CGFloat capTop = 50; // top cap to keep half round as is
CGFloat capLeft = 5; // To repeat it or stretch equally.
UIImage *capImage = [image stretchableImageWithLeftCapWidth:capLeft topCapHeight:capTop];
Swift
let image = UIImage(named: "stretchableImage")
let capTop:Int = 50; // top cap to keep half round as is
let capLeft:Int = 5; // To repeat it or stretch equally.
let capImage = image?.stretchableImage(withLeftCapWidth: capLeft, topCapHeight: capTop)
Same result can be achieved using following function as well.
Objective-C
UIImage *stretchedImage = [image resizableImageWithCapInsets:
UIEdgeInsetsMake(50, 50, 0, 50)];
Swift
var stretchedImage = image?.resizableImage(withCapInsets: UIEdgeInsets(top: 50, left: 50, bottom: 0, right: 50), resizingMode: .stretch)
Note : Keep stretchable image as small as possible otherwise it will not stretch properly with smaller image container(ImageView, Button etc.). You can reduce height & width of your existing image.
