splitview控制器以纵向加载然后加载到横向

Question

我正在动态删除视图并添加splitviewcontroller。我在横向模式下遇到问题。当我在横向模式下进行相同的加载时，视图首先以纵向方式加载，然后转向横向模式。有没有办法解决这个问题。有一个暂时的闪烁，用户体验不愉快。

我今天早些时候遇到了类似的问题，我删除了之前添加到UIWindow的视图，然后添加了我解决问题的其他ViewController，就像这样;

-(void)loginWasSuccessful {

    // discard the login view controller, and nil it out
    [self.loginViewController_iPad.view removeFromSuperview];
    self.loginViewController_iPad = nil;

    self.splitViewController.view.hidden = NO;
    self.splitViewController.view.alpha = NO_ALPHA;

    // create an animation block that'll fade out the splash view, and fade in the split view controller (that houses employee search)
    [UIView animateWithDuration:LOGIN_TO_EMP_SEARCH_FADE_ANIMATION_DURATION animations:^{   

        // remove and nil the splash and login view from the window...
        self.splashView.alpha = NO_ALPHA;
        self.splitViewController.view.alpha = FULL_ALPHA;

    }];

希望这有帮助！
