设置圆角

myView.layer.cornerRadius= 6;

myView.layer.masksToBounds= YES;

 

设置圆角和阴影：(必须分两层)

CALayer *shadowLayer = [CALayerlayer];

shadowLayer.shadowColor = [UIColorblackColor].CGColor;

shadowLayer.shadowOffset =CGSizeMake(0,0);

shadowLayer.shadowRadius =5;

shadowLayer.shadowOpacity =1;

shadowLayer.frame =self.bounds;

shadowLayer.backgroundColor = [UIColorclearColor ].CGColor;

shadowLayer.cornerRadius =5;

shadowLayer.borderColor = [UIColorwhiteColor].CGColor;

shadowLayer.borderWidth =2.0;

[self.layeraddSublayer:shadowLayer];

 

CALayer *borderLayer = [CALayerlayer];

borderLayer.cornerRadius =5;

borderLayer.masksToBounds =YES;

borderLayer.frame = shadowLayer.bounds;

[shadowLayer addSublayer:borderLayer];
