得到通知后跳转到详情

刚好上周我做了这个，UIViewController *vc = [self topVC:[UIApplication sharedApplication].keyWindow.rootViewController]; //拿到当前页面的VC

[vc.navigationController pushViewController:VC animated:YES];//跳转想去的VC

- (UIViewController *)topVC:(UIViewController *)rootViewController{

if ([rootViewController isKindOfClass:[UITabBarController class]]) {

UITabBarController *tab = (UITabBarController *)rootViewController;

return [self topVC:tab.selectedViewController];

}else if ([rootViewController isKindOfClass:[UINavigationController class]]){

UINavigationController *navc = (UINavigationController *)rootViewController;

return [self topVC:navc.visibleViewController];

}else if (rootViewController.presentedViewController){

UIViewController *pre = (UIViewController *)rootViewController.presentedViewController;

return [self topVC:pre];

}else{

return rootViewController;

}

}
