我正在使用以下代码，并且我正在JSON中获取响应字符串。我不知道如何解析它。我应该怎么做未来，如果我想打电话JSON输出的任何方法如何处理来自json输出的responseString并解析它

//源代码

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    dataWebService = [[NSMutableData data] retain]; 

    NSMutableURLRequest *request = [[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://www.googleapis.com/customsearch/v1?key=AIzaSyDzl0Ozijg2C47iYfKgBWWkAbZE_wCJ-2U&cx=017576662512468239146:omuauf_lfve&q=lectures&callback=handleResponse"]]retain];  

    NSURLConnection *myConnection = [NSURLConnection connectionWithRequest:request delegate:self]; 

    [myConnection start];  
} 

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 
{ 
    [dataWebService setLength:0]; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 
{ 
    [dataWebService appendData:data]; 
} 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
    NSString *responseString = [[NSString alloc] initWithData:dataWebService encoding:NSUTF8StringEncoding]; 
    NSLog(@"Response: %@",responseString); 

    [responseString release]; 
    [dataWebService release]; 
}
