Question

我有NSString回复

  {"id":"44","message":"1"} , 

我想获得

的价值

"id" 

和

"message" 

分开。它是来自服务器的响应NSString。

Answer 1

试试这个。

NSData *data = [responseString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *dict = [NSDictionary dictionaryWithDictionary=:[NSJSONSerialization JSONObjectWithData:myData options:NSJSONReadingMutableLeaves error:&error]];
NSLog(@"id:%@", [dict objectForKey:@"id"]);
NSLog(@"message:%@", [dict objectForKey:@"message"]);

它会成功。

Answer 2

你可以得到像

这样的回复

NSData *data = [stringResponse dataUsingEncoding:NSUTF8StringEncoding];
id result = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
NSLog(@"%@", [result objectForKey:@"id"]);

希望这会有所帮助......

Answer 3

NSData *data = [stringResponse dataUsingEncoding:NSUTF8StringEncoding];
//instead of id use NSDictionary
NSDictionary *result = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
NSLog(@"%@", [result objectForKey:@"id"]);

Answer 4

你可以试试这个：

NSDictionary *dic=[response JSONValue];
NSDictionary *id=[dic objectForKey:@"id"];
NSString * message =[dic objectForKey:@"message"];
 NSLog(@"id :%@   Message:%@ ",id,message);

祝你好运！
