enabled和userInteractionEnabled的区别

下面两种设置都能使按钮不能被点击

   button.enabled = NO;
   button.userInteractionEnabled = NO;

区别是:

userInteractionEnabled不改变按钮状态,仅仅使得按钮不能被点击.

enabled更改会改变按钮状态.

举个例子

[button setTitleColor:[UIColor redColor] forState:UIControlStateDisabled];

button.enabled = NO; 按钮进入UIControlStateDisabled状态;
button.userInteractionEnabled = NO; 按钮不会进入UIControlStateDisabled状态.
