是否甚至可以更改UIButtons背景颜色？ [英] Is it even possible to change a UIButtons background color?

问题描述

这一个让我失望。

这是可能的改变iPhone的Cocoa的UIButton的背景颜色。
我已经尝试设置背景颜色，但它只是改变了角落。 setBackgroundColor：似乎是唯一可用的方法。

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

解决方案

这可以通过编写一个副本： / p>

  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; 
  

编辑：ofcourse，你必须 #import< QuartzCore / QuartzCore.h>

编辑：对于所有新读者，您还应该考虑将几个选项添加为另一种可能性。

由于这是一个旧的答案，我强烈建议您阅读有关疑难解答的评论

This one has me stumped.

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]];

解决方案

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;

edit: ofcourse, you'd have to #import <QuartzCore/QuartzCore.h>

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

As this is an old answer, I strongly recommend reading comments for troubleshooting
