PFRelation with CurrentUser在TableView中的帖子

Question

我正在使用Parse.com從數據庫中檢索我需要的數據。

在我的tableview中，我有一個圖像根據這個查詢調用帶有顯示的帖子的CurrentUser的報告的顏色。

-(void)QueryForUpVote { 
    PFQuery *QueryForUpVotePost = [PFQuery queryWithClassName:FF_POST_CLASS]; 
    [QueryForUpVotePost whereKey:@"UP_Vote" equalTo:[PFUser currentUser]]; 
    [QueryForUpVotePost findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { 
     if (!error) { 
      UpVoteCurrentUser = [[NSMutableArray alloc] init]; 
      for (PFObject *ObjectForUpVote in objects) { 
       [UpVoteCurrentUser addObject:ObjectForUpVote]; 
      } 
      [self.FFTableView reloadData]; 
     } 
    }]; 
} 

在泰伯維我加入這個以確保如果有具有與CurrentUser的關係（像一種社交網絡）後

if ([[PFUser currentUser] objectForKey:@"UP_Vote"]) { 
      CellaIMG.MedalCount.image = [UIImage imageNamed:@"FFIMG_Medal_Blu"]; 
      CellaIMG.AddGoPoint.tag = indexPath.row; 
      [CellaIMG.AddGoPoint addTarget:self action:@selector(AddGoPointAction:) forControlEvents:UIControlEventTouchUpInside]; 


     } else { 
      CellaIMG.MedalCount.image = [UIImage imageNamed:@"FFIMG_Medal"]; 
      CellaIMG.AddGoPoint.tag = indexPath.row; 
      [CellaIMG.AddGoPoint addTarget:self action:@selector(DecrementGoPoint:) forControlEvents:UIControlEventTouchUpInside]; 

     } 

我現在的問題是，TableView中無法識別CurrentUser與帖子顯示的關係...當用戶與帖子有特定關係時，我提供的圖片應該變成灰色到藍色......我在哪裏做錯了？

的MutableArray在使用：

- (void)AddGoPointAction:(id)sender { 

    PFObject *AddGoPointToPost = [self.UpVoteCurrentUser objectAtIndex:[sender tag]]; 
    [AddGoPointToPost incrementKey:FF_POST_GOPOINTPOST byAmount:[NSNumber numberWithInt:1]]; 
    PFRelation *RelationForVote = [AddGoPointToPost relationforKey:@"UP_Vote"]; 
    [RelationForVote addObject:[PFUser currentUser]]; 
    [AddGoPointToPost saveInBackground]; 
    [self.FFTableView reloadData]; 
} 

- (void)DecrementGoPoint:(id)sender { 


    PFObject *AddGoPointToPost = [self.UpVoteCurrentUser objectAtIndex:[sender tag]]; 
    [AddGoPointToPost incrementKey:FF_POST_GOPOINTPOST byAmount:[NSNumber numberWithInt:-1]]; 
    PFRelation *RelationForVote = [AddGoPointToPost relationforKey:@"UP_Vote"]; 
    [RelationForVote removeObject:[PFUser currentUser]]; 
    [AddGoPointToPost saveInBackground]; 
    [self.FFTableView reloadData]; 
}

的圖像是隻有一種顏色，因爲你的測試：如果當前用戶具有給予好評

if ([[PFUser currentUser] objectForKey:@"UP_Vote"]) { 

只是檢查。它無法檢查當前用戶是否與'當前'upvote（這將在您的數組中用於填充表視圖）有關係。

您需要更改邏輯以檢查關係。
