Round two corners in UIView
ios, iphone, objective-c, rounded-corners
Solution
CACornerMask introduced in iOS 11, which help to define topleft, topright, bottomleft, bottom right in view layer. Below is example to use.
Here I try to rounded only two top corner:
myView.clipsToBounds = true
myView.layer.cornerRadius = 10
myView.layer.maskedCorners = [.layerMinXMinYCorner,.layerMaxXMinYCorner]

Problem
A little while ago I posted a question about rounding just two corners of a view, and got a great response, but am having problems implementing it. Here is my drawRect: method: ``` - (void)drawRect:(CGRect)rect { //[super drawRect:rect]; <------Should I uncomment this? int radius = 5; CGContextRef context = UIGraphicsGetCurrentContext(); CGContextBeginPath(context); CGContextAddArc(context, rect.origin.x + radius, rect.origin.y + rect.size.height - radius, radius, M_PI, M_PI / 2, 1); CGContextAddArc(context, rect.origin.x + rect.size.width - radius, rect.origin.y + rect.size.height - radius, radius, M_PI / 2, 0.0f, 1); CGContextClosePath(context); CGContextClip(context); } ``` The method is being called, but doesn't seem to affect the outcome of the view. Any ideas why?
