Is it possible to change a UIButtons background color?(是否可以更改 UIButtons 背景颜色?)

问题描述

这个让我难过.

是否可以在 Cocoa for iPhone 中更改 UIButton 的背景颜色.我试过设置背景颜色，但它只会改变角落.setBackgroundColor: 似乎是处理此类事情的唯一方法.

Is it possible at all to change the background color of a UIButton in Cocoa for iPhone. I've tried setting the background color but it only changes the corners. setBackgroundColor: seems to be the only method available for such things.

[random setBackgroundColor:[UIColor blueColor]];
[random.titleLabel setBackgroundColor:[UIColor blueColor]];

推荐答案

这可以通过制作副本以编程方式完成:

This can be done programmatically by making a replica:

loginButton = [UIButton buttonWithType:UIButtonTypeCustom];
[loginButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
loginButton.backgroundColor = [UIColor whiteColor];
loginButton.layer.borderColor = [UIColor blackColor].CGColor;
loginButton.layer.borderWidth = 0.5f;
loginButton.layer.cornerRadius = 10.0f;

当然，你必须 #import <QuartzCore/QuartzCore.h>

对于所有新读者，您还应该考虑添加一些选项作为另一种可能性".供您考虑.

edit: to all new readers, you should also consider a few options added as "another possibility". for you consideration.

由于这是一个旧答案，我强烈建议您阅读评论以进行故障排除
