如何从appdelegate打开视图？

Question

我使用自定义网址方案打开我的应用。 我的代码用于从标签栏打开视图。但是我应该如何打开一个特定的视图。

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

if ([url.host  isEqual: @"main"]) 
{
    UITabBarController *tab = (UITabBarController *)self.window.rootViewController;
    tab.selectedIndex = 0;
}

Answer 1

您需要检查网址方案如下：

 if ([[url scheme] isEqualToString:@"main"]) {
       UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
       UITabBarController *rootViewController = [storyboard instantiateViewControllerWithIdentifier:@"tabBarcontroller"]; // if you are use storyboard .
       [self.Window setRootViewController:rootViewController];
    }

Answer 2

if ([[url scheme] isEqualToString:@"main"]) {
       UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
       UITabBarController *rootViewController = [storyboard instantiateViewControllerWithIdentifier:@"tabBarcontroller"]; // if you are use storyboard .
    tab.selectedIndex = 0;
       [self.Window setRootViewController:rootViewController];
    }
