Question

so, I made my app and everything, and it has a few UI buttons with background images, which worked fine when it was on the computer and i was testing in iphone sim.
now, when i test on a real iphone, the buttons just show up as standard UICustomWhiteRect or whatever it is called.
here is the code i use to make them:

filepath = [[NSBundle mainBundle]
            pathForResource:@"button-half@2x" 
            ofType:@"png"];
[sendAsOneSMSButton setBackgroundImage:[UIImage imageWithContentsOfFile:filepath] forState:UIControlStateNormal];

i also have one for when it is pressed, which i set just like that. and just so no one asks me, the images for the buttons are both in my main folder the same folder my .xcodeproj file is in.
what could i be doing wrong?

SO:
they work in iPhone Simulator,
they show up as normal buttons without images on a real iPhone.

The first thing to check in a case like this is whether your images are really named “[e-mail]”, or if they are in fact “[e-mail]”, “[e-mail]”, or the like. The usual filesystem on OS X (and therefore on the simulator) is case-insensitive, while the filesystem on the device is case-sensitive.
