是的，这里有很多问题的副本。首先研究json.org上的JSON语法（它将花费所有10分钟的时间来学习），然后理解该语法完全转换为NSDictionarys和NSArrays。只需选择你喜欢的解析器。 – 2013-05-13 01:34:04

JSON结果你找回本质上是一个NSDictionary。在您的

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

拉出所需的个人字典条目，并设置单元格文本是从字典返回的NSString。您特定行的indexPath可能会映射到字典的关键字，以使您的生活更轻松。

由于您的回复包含字典数组，因此在解析您的json之后，您将获得字典的NSArry。

// handle it 
NSError *e = nil; 
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: &e]; 

if (!jsonArray) { 
    NSLog(@"Error parsing JSON: %@", e); 
} else { 
    NSLog(@"parsing done and array contains data"); 
}

里面你cellForRowAtIndexPath的tableview委托方法取决于indexpath拿出字典。

[jsonArray objectAtIndex:indexpath.row];
