ios6.0，程序为横屏，出现闪退 
*** Terminating app due to uncaught exception ‘UIApplicationInvalidInterfaceOrientation‘, reason: ‘Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES‘ 
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception

 

自己找到答案了； 
是因为UIImagePickerController是竖屏的，而ipad是横屏的，在ios6.0的横竖屏的问题比较敏感，所以在会挂的。 
解决办法： 
在supported Interface Orientations选中landscapeLeft和LandscapeRight（不选中的话在iOS5.0下第一次运行会竖屏） 
在appdelegate添加 
#if __IPAD_OS_VERSION_MAX_ALLOWED >= __IPAD_6_0 

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window 
{ 

return UIInterfaceOrientationMaskAll; 


} 
#endif 
在该viewController和上一层的viewController中添加 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 

return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight ); 

} 

-(NSUInteger)supportedInterfaceOrientations{ 
return UIInterfaceOrientationMaskLandscape; 
} 

- (BOOL)shouldAutorotate 
{ 
return YES; 
}
