Just two rounded corners? [duplicate]

Question

In my iPad app, I want a second view to appear within the main when the user clicks a button. The new view will be smaller than the first, and darken the background when it is displayed. I want the top two corners of the new view to appear rounded, but using cornerRadius sets all of them rounded. How can I make just two corners rounded?

Answer 1

In Objective C

   // Create the path (with only the top-left corner rounded)
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:imageView.bounds 
                          byRoundingCorners:UIRectCornerTopLeft| UIRectCornerTopRight
                          cornerRadii:CGSizeMake(10.0, 10.0)];
// Create the shape layer and set its path
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = imageView.bounds;
maskLayer.path = maskPath.CGPath;
// Set the newly created shape layer as the mask for the image view's layer
imageView.layer.mask = maskLayer;

This is other to use top rounded corner. Round two corners in UIView

In Swift !!!

myView.clipsToBounds = true
myView.layer.cornerRadius = 10
myView.layer.maskedCorners = [.layerMinXMinYCorner,.layerMaxXMinYCorner]
