UIView上的圆角 [英] Rounded corners on UIView

问题描述

我对如何绕过角落感到困惑，我已经看到其他10个帖子，而且他们没有帮助过我。我这样做是否正确？

I am confused on how I would round corners, I've seen about 10 other posts and non of them have helped me. Am I doing this correctly?

#import "QuartzCore/QuartzCore.h" // in my ViewController.h

- (void)viewDidLoad
{
[super viewDidLoad];

     self.backgroundLayer.cornerRadius = 10.0f;
}

如果有人可以帮我解决这个问题，我将不胜感激。

If somebody could help me out on this it'd be greatly appreciated.

推荐答案

是的，你是对的，但设置 self.backgroundLayer.layer.borderWidth ，我把下面的代码对你的情况有帮助。

Yes, You are correct but set self.backgroundLayer.layer.borderWidth, I put following code might be helpful in your case.

给圆边框 UIView 。

添加 #importQuartzCore / QuartzCore.h fram work。 （你已经完成了）

Add #import "QuartzCore/QuartzCore.h" fram work. (you've already done it)

self.backgroundLayer = [UIView alloc] initWithFrame:CGRectMake(@"As You Want")];
self.backgroundLayer.backgroundColor = [UIColor redColor];
self.backgroundLayer.layer.cornerRadius = 10.0; // set cornerRadius as you want.
self.backgroundLayer.layer.borderColor = [UIColor lightGrayColor].CGColor; // set color as you want.
self.backgroundLayer.layer.borderWidth = 1.0; // set borderWidth as you want.
[self.view addSubView:self.backgroundLayer];

在你的情况下给边界 UIView 。
