UIButton不会变灰 [英] UIButton won't gray out

问题描述

当启用= NO时，UIButton不应该变成灰色/灰色吗？

Isn't UIButton supposed to become grayish/grayer when enabled=NO ?

我在黑背上有一个简单的UIButton（没有自定义图像，没有自定义，只需用IB拖动它并改变大小和标题）。

I have a simple UIButton on a blackbackground (no custom images, no custom nothing, just dragged it with IB and changed size and title).

当我以编程方式设置它以使其变为禁用时它会保持白色地狱！

And when I set it programatically to become disabled it stays white as hell!

现在我正在使用一个小的愚蠢的解决方法：隐藏的blackbg 0,5 alpha UIView在按钮的顶部变得隐藏=当我需要禁用按钮时没有...但我想正确设置按钮...

For now I'm using a small stupid workaround: hidden blackbg 0,5 alpha UIView on top of the button that becomes hidden=NO when I need to disable the button... but I would like to set the button properly...

有什么想法吗？

推荐答案

没有办法使UIButton变灰。但你可以使用这个技巧：

There is no way to make a UIButton "grayer". But you can use that trick :

UIButton *myButton;
myButton.alpha = 0.4;
myButton.enabled = NO;

所以你的UIButton看起来像无法使用;）

So your UIButton looks like unusable ;)
