封装了一个
(UIViewController*)ViewController
{
return [self ViewControllerWithRootViewController:self.view.window.rootViewController];
}-
(UIViewController*)ViewControllerWithRootViewController:(UIViewController*)rootViewController
{
if ([rootViewController isKindOfClass:[UITabBarController class]]) {
UITabBarController *tabBarController = (UITabBarController *)rootViewController;return [self topViewControllerWithRootViewController:tabBarController.selectedViewController];} else if ([rootViewController isKindOfClass:[UINavigationController class]]) {
UINavigationController* navigationController = (UINavigationController*)rootViewController; return [self topViewControllerWithRootViewController:navigationController.visibleViewController];} else if (rootViewController.presentedViewController) {
UIViewController* presentedViewController = rootViewController.presentedViewController; return [self topViewControllerWithRootViewController:presentedViewController];} else {
return rootViewController;}
}
效果不怎么样，求解。
