Question

i was making an application is ios6 but i have to make it compatible for ios5 too. i made weak link to the libraries and they are working fine but one issue arises and i still not solve it. the problem is regarding iphone 5 and iphone 4 sizes. i had some questions:

1. in view under xib what i should pick view size iphone 3.5 or iphone 4?
2. if i place in buttons and other controls according to 4 size than they goes out when i run it on iphone 4 and vice versa?
3. should i need to make two xibs to overcome it?
4. or is there any other method which will resize my view and make it compatible for iphone 4 and 5?

EDIT
iam making application on ios6 and i want my application to run on both iphone 4 and 5.

thanks .

Generally you don’t have to worry about this because iOS can move your controls around for you using either:

• Auto sizing: If supporting iOS versions prior to 6, use the auto sizing masks (sometimes affectionately called "springs and struts", and when accessing programmatically, it’s called the autoresizingMask) so that everything moves arounds appropriately. So select the "size inspector" and adjust the "autosizing" masks:

  

• Autolayout: If you’re developing an iOS 6 and above app, you can also use the new the "autolayout". See Cocoa Auto Layout Guide which has tons of relevant links. Also see the Xcode 4 Users Guide.

• Turn autolayout on and off: If you want to develop an iOS 4/5 compatible app, you may need to turn off "autolayout". If so, go to Interface Builder, click somewhere on the background, select the "file inspector" in the right panel, and examine/change the "Use Autolayout" flag.

  

I’d suggest designing for the 3.5" screen. And let it resize or move your controls for the 4" screen.
