如何使用UIApplication handleOpenURL通知

Question

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];

有人pelase可以帮助我解决这个问题.

正如@Mike K所提到的,你必须实现以下一种方法(或两种方法):

- application:handleOpenURL:
- application:openURL:sourceApplication:annotation:

在您的UIApplicationDelegate上.没有匹配的通知.

示例如下:

-(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;
}
