IOS開發之為視圖繪制單(多)個圓角實例代碼
前言：
為視圖繪制圓角，圓角可以選左上角、左下角、右下角、右上角、全部圓角
//Core RaduiasUIView *actionView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 200, 200)];UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:actionView.bounds byRoundingCorners:UIRectCornerTopRight | UIRectCornerBottomRight cornerRadii:CGSizeMake(20, 20)];CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];maskLayer.frame = actionView.bounds;maskLayer.path = maskPath.CGPath;actionView.layer.mask = maskLayer;
UIRectCorner枚舉值如下:
typedef NS_OPTIONS(NSUInteger, UIRectCorner) { UIRectCornerTopLeft = 1 << 0, UIRectCornerTopRight = 1 << 1, UIRectCornerBottomLeft = 1 << 2, UIRectCornerBottomRight = 1 << 3, UIRectCornerAllCorners = ~0UL};感謝閱讀，希望能幫助到大家，謝謝大家對本站的支持！
