推荐答案

在您实际触摸之前，无法检测到手指悬停在按钮上.

There is no way to detect your finger hovering over the button until you actually touch..

但是您可以使用以下方法来更改按钮的状态，当按钮被按下但尚未释放时或您要处理的任何状态.

But you can use the following methods to change button appearances when its pressed but not yet released or whatever state you like to handle..

- (void)setTitle:(NSString *)title forState:(UIControlState)state;  
- (void)setTitleColor:(UIColor *)color forState:(UIControlState)state;
- (void)setTitleShadowColor:(UIColor *)color forState:(UIControlState)state;
- (void)setImage:(UIImage *)image forState:(UIControlState)state;           
- (void)setBackgroundImage:(UIImage *)image forState:(UIControlState)state;
