如何在Objective-C iOS中解析JSON [英] How to parse JSON in objective-C iOS

问题描述

我想使用AFNetworking库在iOS的Objective-C中解析JSON

I want to parse JSON in Objective-C in iOS using AFNetworking library

{
  "success": 1,
  "row": [
    {
      "amount": 2800
    }
   ]
}

代码-

 arrAmount = [responseObject valueForKey:@"row"];
 NSLog(@"%@",arrAmount);

 NSString *strAmount =[NSString stringWithFormat:@"%@", [arrAmount valueForKey:@"amount"]];

 self.lblAmount.text =[NSString stringWithFormat:@"%@",strAmount];

推荐答案

row的响应包含数组而不是字典，因此从数组的第一个对象访问的数量.

Response of rowcontain array not Dictionary, so access amount from first object of Array.

NSarray *arrAmount = [responseObject objectForKey:@"row"];
if arrAmount.count > 0 {
    NSDictionary *dic = [arrAmount objectAtIndex:0];
    NSString *strAmount = [NSString stringWithFormat:@"%d", [dic objectForKey:@"amount"]];
    self.lblAmount.text = strAmount;
}
