Question

我有一个以tableView开头的项目，但是当用户点击Setup按钮时，我想将更改设置为splitViewController的动画。

我可以轻松更改rootViewController，但动画并不像宣传的那样：

UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"SetupViewController"];
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];

[UIView transitionWithView:self.navigationController.view
                  duration:0.75
                   options:UIViewAnimationOptionTransitionCrossDissolve
                animations:^{
                    app.window.rootViewController = controller;

                }
                completion:nil];

我有没有办法为rootViewController的这个变化设置动画？

这是一个小hackie，但尝试在动画之前设置root并再次返回，所以当你开始动画时新的ViewController得到正确的大小：

UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"SetupViewController"];
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];

UIViewController *currentController = app.window.rootViewController;
app.window.rootViewController = controller;
app.window.rootViewController = currentController;

[UIView transitionWithView:self.navigationController.view.window
                  duration:0.75
                   options:UIViewAnimationOptionTransitionCrossDissolve
                animations:^{
                    app.window.rootViewController = controller;

                }
                completion:nil];

这个解决方案对我有用。
