通过更改委托rootViewContoller来切换视图

Question

我正在尝试将视图从UIViewController切换到SplitViewController。我目前在我的UIViewController中执行此操作：

AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

[UIView transitionWithView:delegate.window duration:0.5 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
    delegate.window.rootViewController = delegate.splitViewController;
} completion:nil];

[self.view removeFromSuperview];

切换视图是否正确？如果是，我仍然有一个问题需要用该方法解决。 它首先在纵向模式下快速显示MasterView，然后在iPad的当前方向模式下显示整个分割视图。

我希望我足够清楚。

感谢您的帮助。

我找到了一种让它从该线程起作用的方法：

RootViewController animation transition, initial orientation is wrong

AppDelegate *delegate =(AppDelegate *)[[UIApplication sharedApplication] delegate];
[UIView transitionWithView:self.window duration:0.5 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
    BOOL oldState = [UIView areAnimationsEnabled];
    [UIView setAnimationsEnabled:NO];
    delegate.window.rootViewController = self.splitViewController;
    [UIView setAnimationsEnabled:oldState];
 } 
 completion:nil];
