Question

我是iOS编程新手，我有一个关于为标签分配值的问题，以下是我从服务中获得的信息

(
{
    EmpName = Peter;
    Relation = SouthAfrica;
},
{
    EmpName = Smith;
    Relation = WestIndies;
},
{
    EmpName = Andrew;
    Relation = England;
},
{
    EmpName = John;
    Relation = Australia;
},
{
    EmpName = Rahul;
    Relation = India;
}
)

上面我有5条记录，我的问题是如何将每个EmpName分配给5个标签，比如peter到Label1，Smith到Label2，Andrew到Label3等等。我只得到第一个empName，下面是我试过的代码。

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {

    NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
    jsonArray=nil;
    NSLog(@"responseString is%@",responseString);
    jsonArray=[NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments|NSJSONReadingMutableLeaves error:nil];
    profileArray=[jsonArray mutableCopy];
    NSLog(@"%lu",(unsigned long)[jsonArray count]);

    if ([jsonArray count]==0) {

        NSLog(@"responseString is%@",responseString);

        UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Validation" message:@"Error Connecting to server" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert show];

    }
    else
    {
        Label1.text = [[jsonArray objectAtIndex:0]objectForKey:@"EmpName"];

    }
}

Answer 1

在标签上添加标签（例如标签= 1表示label1，标签= 2表示label2 .....标签= 5表示标签5）然后在您的其他部分，您可以获得带有标签的所有标签。

    for (int i = 0; i < jsonArray.count; i++) {
        UILabel *lbl = (UILabel *)[self.view viewWithTag:i];
        lbl.text = [[jsonArray objectAtIndex:i] objectForKey:@"EmpName"];
    }

Answer 2

据知道，服务器响应中只有5名员工，但将来这些可能是100或更少。所以你应该使用UITableView。我希望你对UITableView有所了解。

将值分配给标签Objective-C
