How to use UIApplication handleOpenURL Notifications
提问by Omer Abbas
I am trying to handle UIApplication Notifications to get URL Schemes in current open view. I have tried several notifications but i don't know which object contains the URL Schemes.
我正在尝试处理 UIApplication Notifications 以在当前打开的视图中获取 URL Schemes。我尝试了几个通知，但我不知道哪个对象包含 URL Schemes。
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
//[nc addObserver:self selector:@selector(DocumentToDropboxDelegate) name:UIApplicationWillResignActiveNotification object:nil];
[nc addObserver:self selector:@selector(DocumentToDropboxDelegate) name:UIApplicationDidFinishLaunchingNotification object:nil];
Can someone pelase help me with this issue.

As @Mike K mentioned you'll have to implement one (or both) of the following methods:
正如@Mike K 提到的，您必须实现以下一种（或两种）方法：
- application:handleOpenURL:
- application:openURL:sourceApplication:annotation:
on your UIApplicationDelegate. There is no matching notification for them.
在您的 UIApplicationDelegate 上。他们没有匹配的通知。
Example below:
下面的例子：
-(BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
if (url != nil && [url isFileURL]) {
[self.viewController handleOpenURL:url];
}
return YES;
}
//Deprecated
-(BOOL) application:(UIApplication *)application handleOpenURL:(NSURL *)url {
if (url != nil && [url isFileURL]) {
[self.viewController handleOpenURL:url];
}
return YES;
}

application:handleOpenURL:is called on your application delegate - not via a NSNotification. the preferred delegate method to implement is: application:openURL:sourceApplication:annotation:.
application:handleOpenURL:在您的应用程序委托上调用 - 而不是通过 NSNotification。实现优选的代表方法是：application:openURL:sourceApplication:annotation:。
