搭建直播网站iOS指定视图圆角位置

1、最常见的设置圆角的方法无非就是系统的那两句代码

centerView.layer.cornerRadius = 5;
 
centerView.layer.masksToBounds = YES;

2、那么问题来了，如何设置指定圆角位置呢？比如设置右边上下两个圆角？先图再真相

封装后的方法如下：

/*
 originalView：要修改圆角的view
 corners：要修改的圆角取或
 UIRectCornerTopLeft     = 1 << 0,
 UIRectCornerTopRight    = 1 << 1,
 UIRectCornerBottomLeft  = 1 << 2,
 UIRectCornerBottomRight = 1 << 3,
 UIRectCornerAllCorners  = ~0UL
 size：设置的圆角尺寸
 return ：返回的是蒙板层mask、CAShapeLayer对象、
 */
- (CAShapeLayer *)getCornerRoundWithSelfView:(UIView *)originalView byRoundingCorners:(UIRectCorner)corners cornerRadii:(CGSize)size{
 
//绘制左上和左下圆角
 
UIBezierPath*maskPath=[UIBezierPath bezierPathWithRoundedRect:originalView.bounds byRoundingCorners:corners cornerRadii:size];
 
CAShapeLayer *maskLayer = [[CAShapeLayeralloc]init];
maskLayer.frame = originalView.bounds;
maskLayer.path = maskPath.CGPath;
return maskLayer;
 
}

使用方法

toolLab.layer.mask = [self getCornerRoundWithSelfView:toolLab byRoundingCorners:UIRectCornerTopRight | UIRectCornerBottomRight cornerRadii:CGSizeMake(5,5)];
