Glossy buttons are great to have but a pain to create, especially if you are relying on images. Any new button will require you to create the button all over again. Using stretchable images is a help sometimes, but you'll still have a problem once you want to create a new button with a different color. 

This has been pondered over for quite a while and there are a good number of solutions out there. I take my inspiration from the following sources:

This was the first place I found that showed glossy buttons that really looked glossy and were programatically created. Unfortunately, I found the code to be very complex and gave the buttons a yellowish tint, which I didn't like.

This has a snippet of code, but I tightened it up and put a category class around it.

What's great about this is that adding gloss to a button is a breeze and you can set up your buttons using Interface Builder. Just set up your button in interface builder as a custom button and set the background color to the color you want the button to be. Then in your code, just add:

	#import "UIButton+Glossy.h"

and then in your -viewDidLoad:

	[whateverYourButtonIsCalled makeGlossy];
