Question

我无法将字符串“handle”输入到我拥有的UITableView组中;

  for(NSDictionary * dataDict in servers) {

     NSString * handle [dataDict objectForKey:@"handle"];

}

我完全不知道如何利用this语句动态创建带句柄的新单元格。

实际的UITableView位于主视图控制器上，没有任何单元格。如何循环使用值并使用标签创建单元格？

Answer 1

您要为UITableView覆盖此数据源方法，不要忘记为表设置数据源。只需在填充服务器阵列[table reloadData];

后重新加载数据

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return servers.count; //will create cell based on your array count
}

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
     static NSString *CellIdentifier = @"Cell";

     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
     if (cell == nil) 
     {
         cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
     }

     //show handle stirng from server array
     cell.textlabel.text = [[server objectAtIndex:indexPath.row]objectForKey:@"handle"]; 

     return cell;
}

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [arrData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableCell";

    mycustomcell *cell = (mycustomcell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"mycustomcell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
        NSLog( @"NIB = %@",nib);
        NSLog( @"Cell = %@",cell);
    } 

    cell.lblName.text = [[arrData objectAtIndex:indexPath.row] objectForKey:@"Name"];
    cell.lblId.text = [[arrData objectAtIndex:indexPath.row] objectForKey:@"Id"];
    cell.lblGender.text = [[arrData objectAtIndex:indexPath.row] objectForKey:@"Gender"];
    cell.lblAddress.text = [[arrData objectAtIndex:indexPath.row] objectForKey:@"Address"];
    cell.lblPhone.text = [[arrData objectAtIndex:indexPath.row] objectForKey:@"Phone"];
    cell.lblEmail.text = [[arrData objectAtIndex:indexPath.row] objectForKey:@"Email"];

    NSLog(@"tbl %@",cell.lblName.text);


    return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 200;
}

您应该使用UITableViewDataSource协议上提供的以下方法。

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

循环通过JSON数组并将字符串输入到分组的UITableView中
