Question

I am working on a universal app, I used UISplitViewController in doing iPad application. I followed the Universal app guidelines i.e, i keep base SDK as 3.2, iPhone Target OS ad iPhone OS 3.1.3, Taget device as iPhone/iPad. And i used “Adding Runtime Checks for Newer Symbols” for UISplitViewController and UIPopOverController.

Class splitVCClass = NSClassFromString(@"UISplitViewController");

if (splitVC)

{

   UISplitViewController* mySplitViewController = [[splitVCClass alloc] init];

   // Configure the split view controller.

}

I used this in .m files I declared UIPopOverController in .h files also

“dyld: Symbol not found:
_OBJC_CLASS_$_UIPopoverController Referenced from:
/var/mobile/Applications/9E0CE75F-D2A9-4132-AE56-1780928BCF21/UniversalTasks.app/UniversalTasks
Expected in:
/System/Library/Frameworks/UIKit.framework/UIKit
in
/var/mobile/Applications/9E0CE75F-D2A9-4132-AE56-1780928BCF21/UniversalTasks.app/UniversalTasks”

What i have to do can any one help me out

The correct answer is here: Symbol not found: _OBJC_CLASS_$_UIPopoverController

First you must take the original poster’s implicit instructions: move all your iPad-only code (popovers etc) into iPad subclasses etc. Then follow the final answer.
