Iphone and iPod Touch

I have created an app that is working fine on iPod Touch but is creating problems on iPhone. Is there is any difference in iPhone and iPod Touch that can create problems in running an app. The things that 开发者_开发知识库has to be taken care while coding for both.

No, generally "Not at all". Because both iPhone And iPad Touch support the same operating system iOS.

Check out if your iPhone is compatible with the version of iOS code you have developed.
