Question

我有一本字典，其中包含地址详细信息，有时可以保留，“姓名，电子邮件，电话”，其他时间，只是'姓名，移动'

name = "Someone";
email = "Someone@somewhere.com";
telephone = "01000 000000";

或

name = "Someone Else";
mobile = "07700 000000";

我想在详细的表视图中显示这些，在我的脑海中这是有意义的（我知道下面的代码不起作用，但我不知道任何其他方式显示我想要发生的事情）：< / p>

if(selectedData objectForKey=@"name" at indexPath.row){
        cell.textLabel.text = @"Name";
        cell.detailTextLabel.text = [selectedData objectForKey:@"name"];
    } else if(selectedData objectForKey=@"email" at indexPath.row){
        cell.textLabel.text = @"Email";
        cell.detailTextLabel.text = [selectedData objectForKey:@"email"];
    } else if(selectedData objectForKey=@"telephone" at indexPath.row){
        cell.textLabel.text = @"Telephone";
        cell.detailTextLabel.text = [selectedData objectForKey:@"telephone"];
    } else if(selectedData objectForKey=@"mobile" at indexPath.row){
        cell.textLabel.text = @"Mobile";
        cell.detailTextLabel.text = [selectedData objectForKey:@"mobile"];
    }

但我似乎无法正确编码，我甚至可能会咆哮错误的树！任何有关此欢迎的帮助或指示。

我设法通过首先在viewdidload中添加所有键的数组来对其进行排序：

arrayOfKeys = [[NSMutableArray alloc]init];
    for (NSString *key in [selectedData allKeys]){
         NSLog(@"Key:%@", key);
        if(key != @"title" && key != @"name"){
            [arrayOfKeys addObject:key];
        }
    }

然后在cellForRowAtIndexPath中使用：

NSString *currentKey = [arrayOfKeys objectAtIndex:indexPath.section]; 
    if(currentKey == @"email"){
        cell.textLabel.text = @"Email";
        cell.detailTextLabel.text = [selectedData objectForKey:@"email"];
    } else if(currentKey== @"telephone"){
        cell.textLabel.text = @"Telephone";
        cell.detailTextLabel.text = [selectedData objectForKey:@"telephone"];
    } else if(currentKey == @"mobile"){
        cell.textLabel.text = @"Mobile";
        cell.detailTextLabel.text = [selectedData objectForKey:@"mobile"];
    } else if(currentKey == @"company"){
        cell.textLabel.text = @"Company";
        cell.detailTextLabel.text = [selectedData objectForKey:@"company"];
    }

PS。不要忘记在头文件中设置'arrayOfKeys'。

不同的词典和tableviews
