Question

I have seen in the in-built apps for iphone that there is a red delete UIButton. My question is, how do I change the color of the button. Usually there is a ‘tint’ attribute in the attributes inspector but there is not when using a UIbutton.
Is there any way to programmatically change the color?
I appreciate any help.

You can make buttons with colors by using the layer of the button. First add the QuartzCore framework to your project. Then add #import <QuartzCore/QuartzCore.h> into your view class. To make a red button do this

UIButton *myButton = [UIButton buttonWithType: UIButtonTypeCustom];
[myButton setFrame: CGRectMake(10.0f, 10.0f, 300.0f, 44.0f)];
[[myButton layer] setBackgroundColor: [[UIColor redColor] CGColor]];
[self addSubview: myButton];
[myButton release];

Hope this helps!
