为不同的类数据浏览器检索图像 Parse.com [英] Retrieve Image for different Class Data browser Parse.com

问题描述

大家好，我正在尝试显示在该应用中注册的用户的个人资料图片.

Hello everyone I'm trying to display the profile picture of a user registered with the app.

在此查询中，我从照片数据浏览器中的任何位置获取来自不同类的数据.我尝试使用 MatchesQuery 但我找不到正确的组合......可能我的代码是错误的......

In this query I am getting data from a different class from wherever it is in the photo databrowser. I tried with MatchesQuery but I can not find the right combination ... Probably my code is wrong ...

- (void)QueryForTableView {


    PFQuery *QueryForFriend=[PFQuery queryWithClassName:@"Amicizie"];
    [QueryForFriend whereKey:@"A_User" equalTo:[PFUser currentUser]];
    [QueryForFriend includeKey:@"Da_User"];

    PFQuery *RetrievePhoto_User = [PFUser query];
[RetrievePhoto_User whereKey:@"photo" matchesQuery:QueryForFriend];

    [QueryForFriend findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {
            NSLog(@"nome:%@", objects);
            self.UtentiInAttesa = objects ;
            [self.FFTableView reloadData];
        }
    }];


}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"CellaAmici";
    FFCustomCellFriendInAttesa  *cell = [self.FFTableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    if (!cell) {
        cell = [[FFCustomCellFriendInAttesa alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"CellaAmici"];
    }

    PFUser *FriendUser = [self.UtentiInAttesa objectAtIndex:indexPath.row];

    NSString *ValueNomeCognome = [[FriendUser objectForKey:@"Da_User"] valueForKey:FF_USER_NOMECOGNOME];
    cell.FFNomeFriendLabel.text = ValueNomeCognome;


    cell.FFFotoProfiloInAttesa.file = [FriendUser objectForKey:@"photo"];
    cell.FFFotoProfiloInAttesa.image = [UIImage imageNamed:@"FFNoFotoUSer"];

    [cell.FFFotoProfiloInAttesa.layer setMasksToBounds:YES];
    [cell.FFFotoProfiloInAttesa.layer setCornerRadius:22.5f];
    [cell.FFFotoProfiloInAttesa loadInBackground];

    return cell;
}

推荐答案

和你聊了几句.以下代码是不必要的和错误的.如此简单的删除它，你就设置好了:

After a little chat with you. The following code is unnecessary and wrong. So simple remove it and you are set:

PFQuery *RetrievePhoto_User = [PFUser query];
[RetrievePhoto_User whereKey:@"photo" matchesQuery:QueryForFriend];
