ios4 - How to make a universal app (iPad and iphone 4.1) runs on iPod 3.1.3 -

-

i building universal iphone/ipad , set deployment target 3.0. can run on ipad 3.2 , iphone 4.1. however, when build , run on ipod 3.1.3, runtime automatically picks ipad code path , tell me cannot find uipopovercontroller , uimenuitem. in iphone path code, don't use that.

it builds , when trying run, says error , cannot find:

dyld: symbol not found: _objc_class_$_uipopovercontroller   referenced from: /var/mobile/applications/my_app   expected in: /system/library/frameworks/uikit.framework/uikit

editted :

if remove of ipad classes , set app.info main nib bundle iphone only. then, works well. think problem runs ipad code. don't know what's wrong ipod or project

you need make runtime tests classes not present on 3.1.3. cannot have code [uipopovercontroler alloc], , must weaklink frameworks.

see answers question:

how should approach building universal ios app include ios 4 features, though ipad doesn't yet run ios 4?

(the question different yours, root problem same one.)

(assuming mingw) i'm still trying handle on c++ stuff, after reading coun...
