给控件设置圆角平时大家用的最多应该是layer.cornerRadius这个属性吧但是这个属性设置成功后是4个角都是圆角类型的;

现在控制器里创建一个imageVIew

 UIImageView *imageView=[[UIImageView alloc]initWithFrame:CGRectMake(100, 100, 100, 50)];    imageView.backgroundColor=[UIColor redColor];    [self.view addSubview:imageView];

在Healp.h 中根据你的控件决定

/* 适用于label imageView view  */+(void)viewBeizerRect:(CGRect)rect view:(UIView *)view  corner:(UIRectCorner)corner cornerRadii:(CGSize)radii;  /* 适用于button */+(void)ControlBeizerRect:(CGRect)rect Control:(UIControl *)Control  corner:(UIRectCorner)corner cornerRadii:(CGSize)radii;

在 Healp.m 中

/*  适用于label imageView view  */+(void)viewBeizerRect:(CGRect)rect view:(UIView *)view corner:(UIRectCorner)corner cornerRadii:(CGSize)radii{    UIBezierPath  *maskPath= [UIBezierPath bezierPathWithRoundedRect:rect byRoundingCorners:corner cornerRadii:radii];    CAShapeLayer *maskLayer = [CAShapeLayer layer];    maskLayer.frame =view.bounds;    maskLayer.path = maskPath.CGPath;    view.layer.mask = maskLayer;}  /* 适用于button  */+(void)ControlBeizerRect:(CGRect)rect Control:(UIControl *)Control  corner:(UIRectCorner)corner cornerRadii:(CGSize)radii{    UIBezierPath  *maskPath= [UIBezierPath bezierPathWithRoundedRect:rect byRoundingCorners:corner cornerRadii:radii];    CAShapeLayer *maskLayer = [CAShapeLayer layer];    maskLayer.frame =Control.bounds;    maskLayer.path = maskPath.CGPath;    Control.layer.mask = maskLayer;}

然后在控制器里调用

[Healp viewBeizerRect:imageView.bounds view:imageView corner:UIRectCornerBottomRight cornerRadii:CGSizeMake(20, 20)];

就可以了

设置圆角的属性

typedef NS_OPTIONS(NSUInteger, UIRectCorner) {

UIRectCornerTopLeft = 1 << 0, 左上

UIRectCornerTopRight = 1 << 1,右上

UIRectCornerBottomLeft = 1 << 2,左下

UIRectCornerBottomRight = 1 << 3,右下

UIRectCornerAllCorners = ~0UL 全角

};
