查看角半径问题

Question

我有一个 UIView 那个 UIView 我有 UIImageView & 我所做的是将 cornerRadius 设置为那个 UIView 并且还设置borderWidth 但在那之后我得到了将近 1 个像素 space UIView 那么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;

Answer 1

尝试一下它的工作正常......我改变了你的项目。给我你的电子邮件 ID，我会发给你。

_view1.layer.cornerRadius = _view1.frame.size.height / 2;
_view1.layer.masksToBounds = YES;
_view1.layer.borderColor = [UIColor whiteColor].CGColor;
_view1.layer.borderWidth = 20;

_img.layer.cornerRadius = _img.frame.size.height / 2 ;
_img.clipsToBounds = YES;

Answer 2

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;
