ios - iOS 上的 Dropbox API 无法链接

Question

我无法让我的应用链接到 iOS 上的保管箱。

我创建 session 并询问它是否已链接...如果没有，它会打开 Dropbox 以获得授权。我说是，然后它返回到我的应用程序并发送通知以开始上传。

但是 isLinked 仍然是 NO，所以如果我尝试上传文件失败。任何建议表示赞赏。

有趣的是，从未调用 -sessionDidReceiveAuthorizationFailure: userId: 委托(delegate)方法。

-(void)connectToDropbox{
    if (!dbSession) {
        dbSession    = [[DBSession alloc] initWithAppKey:@"key"
                                                   appSecret:@"secret"
                                                      root:kDBRootDropbox];

        dbSession.delegate = self;    
        [DBSession setSharedSession:dbSession];
    }


    if ([[DBSession sharedSession] isLinked]) {
        [self beginUpload:nil];
    } else {
        [[DBSession sharedSession] linkFromController:self.currentViewController];
    }
}

- (void)beginUpload:(NSNotification *)note {

    if (![[DBSession sharedSession] isLinked]) {
        NSError * error = [NSError errorWithDomain:@"myApp"
                                              code:0
                                          userInfo:@{NSLocalizedDescriptionKey : @"Could not link to Dropbox"}];

        [[NSNotificationCenter defaultCenter] postNotificationName:kErrorDidOccurNotification object:error];
        NSLog(@"File upload failed with error: %@", error);
        return;
    }

   ///do the upload if we make it here.
}


- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation NS_AVAILABLE_IOS(4_2){


    if ([sourceApplication isEqualToString:@"com.getdropbox.Dropbox"]) {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"beginDropboxUpload" object:nil];
    }
/// more code
}

您在应用委托(delegate)中的代码不正确。你需要这样的东西:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation NS_AVAILABLE_IOS(4_2) {
    if ([[DBSession sharedSession] handleOpenURL:url]) {
        NSString *query = url.query;
        if ([[url absoluteString] rangeOfString:@"cancel"].location == NSNotFound) { // NO_I18N
            [[NSNotificationCenter defaultCenter] postNotificationName:@"beginDropboxUpload" object:nil];
        } else {
            // Link cancelled
        }
    } else {
        // Something other than Dropbox
    }
}
