问题描述

我想在我的表视图中显示一个数据在parse.com上的数据库
我可以显示数组中的第一项，但不显示其余项。

I am tying to display in my table view an array that is on a database on parse.comI can display the first item in the array, but not the rest.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell==nil){
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }
    _ListArray = [object objectForKey:@"content"];
    NSLog(@"OBJECT = %@",_ListArray);
    NSString *cellValue = [NSString stringWithFormat:@"%@", [_ListArray objectAtIndex:indexPath.row]];

    cell.textLabel.text = cellValue;

    if(refresh <counter)
    {
        NSString *br = @"<br>";
        List = [NSString stringWithFormat:@"%@%@%@", List, br, cell.textLabel.text];
        NSLog(@"%@",List);
        refresh ++;
    }
    cell.accessoryType =UITableViewCellAccessoryDisclosureIndicator;

    return cell;
}

如果我尝试使用：

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [_ListArray count];
}

表格中没有任何内容。

编辑更新：

删除了self.ListArray并使用_ListArray。

did remove the self.ListArray and going with _ListArray.

在h文件中：

NSMutableArray *ListArray;
...
@property (retain, atomic) NSMutableArray *ListArray;

然后在m档案中：

@synthesize ListArray = _ListArray;

关于：

self.ListArray = [object objectForKey:@"content"];

对象是PFObject。

the object is the PFObject.

我有queryForTable，我从解析中获取数据。

i have queryForTable where i get the data from parse.

- (PFQuery *)queryForTable {

    PFQuery *query = [PFQuery queryWithClassName:@"List"];
    [query whereKey:@"user" equalTo:[PFUser currentUser]]; // user
    [query whereKey:@"objectId" equalTo:[theListID objectId]]; // the specific list
    counter =[query countObjects];
    NSLog(@"%d",counter);

    // If Pull To Refresh is enabled, query against the network by default.
    if (self.pullToRefreshEnabled) {
        query.cachePolicy = kPFCachePolicyNetworkOnly;
    }

    // If no objects are loaded in memory, we look to the cache first to fill the table
    // and then subsequently do a query against the network.
    if ([self.objects count] == 0) {
        query.cachePolicy = kPFCachePolicyCacheThenNetwork;
    }

    [query orderByDescending:@"createdAt"];

    return query;

}

和objectForKey：@content];
content是我的类中解析
的列的名称所以我需要说出我想要的类中的哪个对象，那就是名为content的数组列

And to the objectForKey:@"content"];content is the name of the column in my class on parseso i need to say what object from the class i want to get, and that is the array column named "content"

logg，（NSLog在阵列上有效。

The logg, (when the NSLog is active on the array.
