Question

我正在使用以下代码，我在JSON中获取响应字符串。我不知道如何解析它。如果我想在JSON输出上调用任何方法

，我该怎么办

//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];
}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    NSLog(@"Error during connection: %@", [error description]);
}
