setOrientation in UIDevice is depreciate for iOS 5 and upper version. If we want to change or limit the orientation of current view controller. We still need to set the device orientation. In fact we still get 3 ways to handle it:
if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) { SEL selector = NSSelectorFromString(@"setOrientation:"); NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]]; [invocation setSelector:selector]; [invocation setTarget:[UIDevice currentDevice]]; int val = UIInterfaceOrientationLandscapeRight; [invocation setArgument:&val atIndex:2]; [invocation invoke]; }
2nd:
objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationLandscapeLeft);
3rd:
UIViewController *controller = [[UIViewController alloc] init]; [self presentViewController:controller animated:NO completion:nil]; [self dismissViewControllerAnimated:NO completion:nil];
The first 2 method may have a risk to be rejected. I'm afraid Apple may think it a private API. The 3rd method, ok, I agree it's not a beautiful solution.
