如何圆角的按钮 [英] How to round the corners of a button

问题描述

我有一个矩形图像（jpg），并希望使用它来填充圆角的按钮的背景在xcode。

I have a rectangle image (jpg) and want to use it to fill the background of a button with rounded corner in xcode.

我写了以下内容： / p>

I wrote the following:

UIButton *button = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
CGRect frame = CGRectMake(x, y, cardWidth, cardHeight);
button.frame = frame;
[button setBackgroundImage:backImage forState:UIControlStateNormal];

但是，我得到的按钮没有它的四边角：它是一个看起来像我的原始图像的纯矩形。

However, the button I get with that approach doesn't have its corners rounded: it is instead a plain rectangle that looks exactly like my original image. How can I get instead an image with rounded corner to represent my button?

谢谢！

推荐答案

我想我有你的问题，我试图与UITextArea的以下解决方案，我想这将与UIButton一起工作。

I think I got your problem, I tried the following solution with the UITextArea and I suppose this will work with UIButton as well.

所有导入到您的.m文件中 -

first of all import this in your .m file -

#import <QuartzCore/QuartzCore.h>

，然后在 loadView

    yourButton.layer.cornerRadius = 10; // this value vary as per your desire
    yourButton.clipsToBounds = YES;

希望这适合你，如果是的话，沟通。

Hope this works for you and if yes do communicate.
