Creating iOS 5 Apps Discussion > Page 198 - another option to create custom buttons
These are all good alternatives.
I'd highly recommend using stretchable images whenever possible, just to cut down on memory usage. Note, however, that the stretchableImageWithLeftCapWidth:topCapHeight: is deprecated. You should use resizableImageWithCapInsets: instead. I believe I cover this (briefly) in Chapter 8.

Great opportunity to learn about Core Animation to create a custom button. Just thought I'd mention a couple other options I've used...
// Copy this to UnitSelectorViewController.m viewDidLoad...
// Option 1: Use ButtonMaker (https://github.com/dermdaly/ButtonMaker) to create a 29 x 46 button in your choice of color and import button.png and button-highlight.png
// Option 2: Download assets from http://developer.apple.com/library/ios/samplecode/uicatalog/UICatalog.zip and import whiteButton.png and blueButton.png (change button.png to whiteButton.png, and button-highlight to blueButton.png)
UIImage *buttonImageNormal = [UIImage imageNamed:@"button.png"];
UIImage *stretchableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[self.doneButton setBackgroundImage:stretchableButtonImageNormal forState:UIControlStateNormal];
UIImage *buttonImagePressed = [UIImage imageNamed:@"button-highlight.png"];
UIImage *stretchableButtonImagePressed = [buttonImagePressed stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[self.doneButton setBackgroundImage:stretchableButtonImagePressed forState:UIControlStateHighlighted];
You'll also need to set the background color of the button to Default in the storyboard.
