AFNetworking 2.0 -使用responseObject作为NSDictionary
AFNetworking 2.0 -使用responseObject作为NSDictionary
提问于 2013-09-30 12:55:39
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];这是AFNetworking 2.0中用于发送GET请求的recommended way。我想要获取json中特定键的值，所以我想使用responseObject作为NSDictionary。这就是我所尝试的：
NSError *jsonError = nil;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:(NSData *)responseObject options:kNilOptions error:&jsonError];它不起作用：
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary bytes]: unrecognized selector sent to instance 0xa048120'如何在responseObject中获取特定键的值
