UIImageView不能设置圆角的解决方法

self.leftPanelView.layer.cornerRadius =10;self.leftPanelView.clipsToBounds = YES;设置圆角的同时，也要设置 clipsToBounds = YES如果要设置两个圆角，而不是四个角可以使用

Create a CAShapeLayer
Set its path to be a CGPathRef based on view.bounds but with only two rounded corners (probably by using +[UIBezierPath bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:])
Set your view.layer.mask to be the CAShapeLayer

UIView*view =[[UIView alloc] initWithFrame:frame];CALayer*layer =[CALayer layer];UIBezierPath*shadowPath =[UIBezierPath bezierPathWithRoundedRect:frame byRoundingCorners:(UIRectCornerTopLeft|UIRectCornerTopRight) cornerRadii:CGSizeMake(3.0,3.0)];layer.shadowPath = shadowPath.CGPath;view.layer.mask = layer;
