Magnify button on iphone

Is there a way to magnify a button when you touch it? similar to the keyboard when writing a text message, the key you press gets magnified so you can see which button you a开发者_如何学Gore actually pressing.

You can also do this by this method:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;

and when the user touches your button then you can change the button's frame (buttton.frame).

I would suggest you to have two different appearers of your button and it can be achieved through the your button states : Link to state:

 UIControlStateNormal,
   UIControlStateHighlighted,

Now you need to use the following set of function

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

Hope your could magnify your button to some extend.
