所以我想访问fullname并加载到我的tableview方法ex - user.fullname [indexpath.row] ..但是我不知道访问和加载allusers进入我的表视图的方法。

我尝试了以下方法而没有indexpath.row，所以它只将最后一个用户加载到tableview。

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return multiCombinedArray.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    //  UserTableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:@"contactUserCell" forIndexPath:indexPath];
    static NSString *cellIdentifier = @"UserTableViewCellIdentifier";
    ChatUserTableViewCell *chatUsersCell = (ChatUserTableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if(chatUsersCell == nil)
    {
        chatUsersCell = [[ChatUserTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }

  //  chatUsersCell.chatUserFullName.text = multiCombinedArray

    for(QBUUser *user in multiCombinedArray)
    {
        chatUsersCell.chatUserFullName.text = [NSString stringWithFormat:@"%@",user.fullName];

    }
  return chatUserCell;
}

请帮我快速访问全名并将所有名称加载到表格视图中。

Answer 1

您无需绕过multiCombinedArray，indexPath.row访问就足够了，所以

替换此

for(QBUUser *user in multiCombinedArray)
    {
        chatUsersCell.chatUserFullName.text = [NSString stringWithFormat:@"%@",user.fullName];

    }

通过此

   QBUUser * user = multiCombinedArray[indexPath.row];
   chatUsersCell.chatUserFullName.text = [NSString stringWithFormat:@"%@",user.fullName];

from sklearn.metrics import f1_score
y_true = [0, 1, 2, 2, 2]
y_pred = [0, 0, 2, 2, 1]
target_names = ['class 0', 'class 1', 'class 2']

print(f1_score(y_true, y_pred, average=None)

如何从基于NSArray的数据模型（NSobject）访问对象？
