在appDelegate中用新的视图控制器替换现有的视图控制器作为根视图控制器时，有没有办法获得过渡/动画效果？

您可以将rootViewController的切换包装在过渡动画块中：
[UIView transitionWithView:self.window
duration:0.5
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{ self.window.rootViewController = newViewController; }
completion:nil];Stack Overflow用户

试试这个吧。对我来说很好。
BOOL oldState = [UIView areAnimationsEnabled];
[UIView setAnimationsEnabled:NO];
self.window.rootViewController = viewController;
[UIView transitionWithView:self.window duration:0.5 options:transition animations:^{
//
} completion:^(BOOL finished) {
[UIView setAnimationsEnabled:oldState];
}];编辑：
这个更好。
- (void)setRootViewController:(UIViewController *)viewController
withTransition:(UIViewAnimationOptions)transition
completion:(void (^)(BOOL finished))completion {
UIViewController *oldViewController = self.window.rootViewController;
[UIView transitionFromView:oldViewController.view
toView:viewController.view
duration:0.5f
options:(UIViewAnimationOptions)(transition|UIViewAnimationOptionAllowAnimatedContent|UIViewAnimationOptionLayoutSubviews)
completion:^(BOOL finished) {
self.window.rootViewController = viewController;
if (completion) {
completion(finished);
}
}];

为了避免以后在应用程序中使用过渡翻转时出现问题，最好也从堆栈中清除旧视图
UIViewController *oldController=self.window.rootViewController;
[UIView transitionWithView:self.window
duration:0.5
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^{ self.window.rootViewController = nav; }
completion:^(BOOL finished) {
if(oldController!=nil)
[oldController.view removeFromSuperview];
}];页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
