用Facebook上傳照片到Facebook的錯誤iOS SDK 3.1.1

Question

我正在開發一個應用程序，它允許用戶上傳他們的照片到Facebook的消息。 但它不能順利運行，有時它會完美運行，並且會多次返回此錯誤。

2012-10-09 21:12:41.320 TimeLapse[1724:707] Error: HTTP status code: 200 
2012-10-09 21:12:41.329 TimeLapse[1724:707] Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0xf352290 {com.facebook.sdk:ErrorInnerErrorKey=Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0xf351840 {NSErrorFailingURLStringKey=https://graph.facebook.com/me/photos?sdk=ios&access_token=.....&migration_bundle=fbsdk%3A20121003&message=Ghh&format=json, NSErrorFailingURLKey=https://graph.facebook.com/me/photos?sdk=ios&access_token=....&migration_bundle=fbsdk%3A20121003&message=Ghh&format=json, NSLocalizedDescription=The request timed out., NSUnderlyingError=0xf3518b0 "The request timed out."}, com.facebook.sdk:HTTPStatusCode=200} 

這裏是我的代碼

-(void)startPostPhotoToFacebook:(UIImage *)image withMessage:(NSString *)message { 
    NSArray *arrPermission = [NSArray arrayWithObjects:@"publish_stream", nil]; 

    if (FBSession.activeSession.state == FBSessionStateOpen) { 
     NSLog(@"Session is opened already"); 
     [self postPhotoToFacebook:image withMessage:message]; 
    } 
    else { 
     NSLog(@"Need to open session"); 

     [FBSession openActiveSessionWithPublishPermissions:arrPermission defaultAudience:FBSessionDefaultAudienceEveryone allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState state, NSError *error) { 
      if (!error) { 
       [self sessionStateChangedForPostPhotoToFacebook:session state:state error:error withImage:image andMessage:message]; 
      } 
      else { 
       NSLog(@"Open active session failed"); 
      } 
     }]; 
    } 
} 

-(void)sessionStateChangedForPostPhotoToFacebook:(FBSession *)session state:(FBSessionState)state error:(NSError *)error withImage:(UIImage *)image andMessage:(NSString *)message { 
    switch (state) { 
     case FBSessionStateOpen: { 
      [self startPostPhotoToFacebook:image withMessage:message]; 
     } 
      break; 
     case FBSessionStateClosed: 
     case FBSessionStateClosedLoginFailed: 
      [FBSession.activeSession closeAndClearTokenInformation]; 
     default: 
      break; 
    } 

    if (error) { 
     NSLog(@"error"); 
    } 
} 

-(void)postPhotoToFacebook:(UIImage *)image withMessage:(NSString *)message { 
    if (message == nil) { 
     message = @""; 
    } 
    NSMutableDictionary *params = [NSMutableDictionary dictionary]; 
    [params setObject:message forKey:@"message"]; 

    [params setObject:image forKey:@"source"]; 

    FBRequest *request = [FBRequest requestWithGraphPath:@"me/photos" parameters:params HTTPMethod:@"POST"]; 

    FBRequestConnection *fbConnection = [[FBRequestConnection alloc] initWithTimeout:10]; 
    [fbConnection addRequest:request completionHandler:^(FBRequestConnection *connection, id result, NSError *error) { 
     if (!error) { 
      NSLog(@"Result: %@", result); 
      [myMainViewController finishPostPhotoToFacebook]; 
      [fbConnection release]; 
     } 
     else { 
      NSLog(@"%@", error.description); 
      [myMainViewController errorPostPhotoToFacebook]; 
      [fbConnection release]; 
     } 
    }]; 

    [fbConnection start]; 
} 

任何一個知道如何解決這一問題？ 非常感謝你

你從Facebook上超時。請參閱說明

NSLocalizedDescription=The request timed out., 

您的超時設置很短。 Facebook SDK默認超時180. 由於您處理圖片上傳10秒可能並不總是足夠的。把它設置得更高一些，比如30秒。
