状态栏可以旋转，但应用程序不能在iPhone上运行-在iPad上可以正常使用吗？

Question

Long time lurker, always tried very hard to search and have found many answers this way. This is the first time I have found nothing that fixes my problem. This is also my first solo app, as I am a new developer.

I have two devices- an iOS 8.1 iPhone 6, and an iOS 7 iPad Mini Retina 2.

I am building my first iOS app. It uses storyboards for a UITabBarController with three tabs, each of which contains a UINavigationController and a custom sub view controller (such as a subclass of tabbarcontroller or collectionviewcontroller).

Under Deployment Info: Deployment Target is set to 7.0 and Universal. iPhone and iPad both use the MainStoryboard main interface, with all four Device Orientations checked for both.

My AppDelegate starts with:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]];

UITabBarController *initViewController = (UITabBarController *)[storyboard instantiateViewControllerWithIdentifier:@"rootTabBarController"];

NSLog(@"%d %d",initViewController.shouldAutorotate,initViewController.shouldAutomaticallyForwardRotationMethods);

[self.window setRootViewController:initViewController];

Note the NSLog; it prints "1 0".

So from what I can see- the tab bar should auto rotate.

On my iPhone, when I turn the device sideways, the status bar on the top rotates- but the content remains upright. If I hit the Home button and switch back to the app while holding it sideways, everything goes wonky- the content rotates but doesn't rearrange the layout, so it remains vertical, and thus gets cut off and there's a big black section on the side.

On my iPad, though- everything works fine! The application rotates as expected and resizes itself.

What am I doing wrong here? Thank you tremendously for any help.

Answer 1

Why are you programmatically loading the storyboard? If there's no specific need to do that, I'd suggest just using the template app delegate code. Better yet, create a completely new, fresh project and just copy over your storyboard. It won't necessarily make sense, but... I bet it will work!
