ios – 查看角半径问题

我有一个UIView,在UIView我有UI ImageView&我所做的是将cornerRadius设置为该UIView并设置borderWidth但是在UIView之后我得到了近1个像素空间所以我该如何解决这个问题？

view1.clipsToBounds = YES;
view1.layer.cornerRadius = 150;
view1.layer.masksToBounds = YES;
view1.layer.borderColor = [UIColor whiteColor].CGColor;
view1.layer.borderWidth = 50;
view1.layer.opaque = NO;

您可以查看下面显示1像素间距的图像.

解决方法

尝试使用它,它将在我的项目中正常工作

self.view1.layer.cornerRadius=_slider1.value;//Value as per your requirement

CALayer *borderLayer = [CALayer layer];
CGRect borderFrame = CGRectInset(CGRectZero,-1,-1);
[borderLayer setBackgroundColor:[[UIColor clearColor] CGColor]];
[borderLayer setFrame:borderFrame];
[borderLayer setCornerRadius:_slider1.value];//Value as per your requirement
[borderLayer setBorderWidth:_slider2.value];//Value as per your requirement
[borderLayer setBorderColor:[[UIColor whiteColor] CGColor]];
[self.view1.layer addSublayer:borderLayer];

self.view1.clipsToBounds=YES;
