I'm trying to add a 1px black drop shadow to a button label with no luck. I've tried this:self.setTitleShadowOffset = CGSizeMake(0, -1); but I get:

Request for member 'setTitleShadowOffset' in something not a structure or union

Any suggestions would be fantastic thanks!

解决方案

The other answers do not properly set the shadow color (I suspect they didn't notice because they were trying to set the shadow color to what it is by default, black.)

This code worked for me to add a white shadow to the text of my button:

myButton.titleLabel.shadowOffset = CGSizeMake(0, 1); [myButton setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateNormal];
