本文解决iOS6系统中在横屏模式下使用UIImagePickerController时出现的闪退问题，通过在调用类中加入特定代码实现兼容性优化。

IOS6横屏时调用UIImagePickerController时会出现闪退：

*** Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES'

解决办法，在调用UIImagePickerController的类中加入下面代码：

@interface UIImagePickerController (LandScapeImagePicker)

@end

@implementation UIImagePickerController (LandScapeImagePicker)

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    if ([self isKindOfClass:[UIImagePickerController class]]) {
        return UIInterfaceOrientationPortrait;
    }
    return [self.topViewController preferredInterfaceOrientationForPresentation];
}
@end
