Parse.com 查询 PFUser 当前用户

Question

我

发布的查询中的每个人问好，我正在尝试检索所有帖子和PfUserCurrent与PfUserCurrent分享友谊的人的所有帖子。

查询工作正常，但我只有一个问题，查询向我显示了当前用户之友的所有帖子，但没有显示当前用户发送的帖子......我已经尝试了几次尝试，但我无法解决这个问题......你能解释一下我错在哪里吗？

-(void)QueryForPost {
    PFQuery *QueryForFriend=[PFQuery queryWithClassName:@"Friendships"];
    [QueryForFriend whereKey:@"To_User" equalTo:[PFUser currentUser]];
    [QueryForFriend whereKey:@"STATUS"  equalTo:@"Confirmed"];

    PFQuery *QueryYES = [PFQuery queryWithClassName:@"Post"];
    [QueryYES whereKey:@"FLASH_POST" equalTo:[NSNumber numberWithBool:YES]];
    [QueryYES whereKey:@"UserSelected" equalTo:[PFUser currentUser]];

    PFQuery *QueryNO = [PFQuery queryWithClassName:@"Post"];
    [QueryNO whereKey:@"FLASH_POST" equalTo:[NSNumber numberWithBool:NO]];
    [QueryNO whereKey:@"Author" matchesKey:@"From_User" inQuery:QueryForFriend];
    PFQuery *query = [PFQuery orQueryWithSubqueries:@[QueryYES,QueryNO]];
    [query includeKey:@"Author"];
    [query orderByDescending:FF_CREATEDAT];
    [query findObjectsInBackgroundWithBlock:^(NSArray *results, NSError *error) {
        if (!error) {
            NSLog(@"%@", results);
            ArrayforPost = [[NSMutableArray alloc] init];
            for (PFObject *object in results) {
                [ArrayforPost addObject:object];
            }
            [self.FFTableView reloadData];
        }
    }];

}

经过与@rory长时间的讨论，我们得出正确的答案：

-(void)QueryForPost {
PFQuery *QueryForFriend=[PFQuery queryWithClassName:@"Amicizie"]; 
[QueryForFriend whereKey:@"A_User" equalTo:[PFUser currentUser]]; 
[QueryForFriend whereKey:@"STATO" equalTo:@"Confermato"]; 
[QueryForFriend includeKey:@"Da_User"]; 
PFQuery *QueryYES = [PFQuery queryWithClassName:@"Post"]; 
[QueryYES whereKey:@"FLASH_POST" equalTo:[NSNumber numberWithBool:YES]]; 
[QueryYES whereKey:@"Scelti" equalTo:[PFUser currentUser]]; 
PFQuery *normalPostByFriends = [PFQuery queryWithClassName: @"Post"]; 
[normalPostByFriends whereKey: @"FLASH_POST" equalTo: [NSNumber numberWithBool: NO]]; 
[normalPostByFriends whereKey: @"Utente" matchesKey:@"Da_User" inQuery:QueryForFriend]; 
PFQuery *normalPostByUser = [PFQuery queryWithClassName:@"Post"]; 
[normalPostByUser whereKey: @"FLASH_POST" equalTo: [NSNumber numberWithBool: NO]]; 
[normalPostByUser whereKey: @"Utente" equalTo: [PFUser currentUser]];
PFQuery *query = [PFQuery orQueryWithSubqueries:@[QueryYES,normalPostByFriends,normalPostByUser  ]];
[query includeKey:@"Author"];
[query orderByDescending:FF_CREATEDAT];
[query findObjectsInBackgroundWithBlock:^(NSArray *results, NSError *error) {
    if (!error) {
        NSLog(@"%@", results);
        ArrayforPost = [[NSMutableArray alloc] init];
        for (PFObject *object in results) {
            [ArrayforPost addObject:object];
        }
        [self.FFTableView reloadData];
    }
}];
}

通过进行另一个查询以显示当前用户的正常帖子并修改QueryForFriend以获得正确的查询来处理该问题
