Storyboard - How to segue to a SplitViewController from a Viewcontroller in navigation based application

问题

I have a navigation controller based iPad application. I am using storyboards for the app design. From one of the ViewControllers in the Navigation stack, I need to segue to a screen showing splitviewcontroller. how to I go about that ?

Thanks in advance for any help on this.

回答1:

A UISplitViewController must always be the first/main view controller you use. You can't use it from a UINavigationController or a UITabBarController or similar.

I had the exact same problem and I solved it by implementing a custom segue.

@implementation LoginSegue
- (void) perform {
    NSLog(@"Do the segue you way");
    UIViewController *src = self.sourceViewController;
    UIWindow *window = src.view.window;
    [window addSubview:[self.destinationViewController view]];
    window.rootViewController = self.destinationViewController;
}
@end

This seems to have worked for me. I hope this is an acceptable solution when I submit the code to apple.
