How to use AFNetwowrking2.0 code for this Example url? - ios

Question

Hi I have one example url Which returns JSON Format. but when i use AFNetWorking2.0 to get the response from that URL, i am not getting correct Response. Here i am sending my code also.
- (void)testHTTPS {
AFSecurityPolicy *securityPolicy = [[AFSecurityPolicy alloc] init];
[securityPolicy setAllowInvalidCertificates:YES];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
//manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager setSecurityPolicy:securityPolicy];
[manager GET:#"xxxxx"
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
NSString* newStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
I am getting JSON Dic always nil. and if i print "newstr" i am getting html format response. can anyone please find correct way?
I have done as you said John but i am getting the below result

Answer 1

The problem is that you're using the AFHTTPResponseSerializer rather than AFNetworking's AFJSONResponseSerializer. Therefore, when the response comes in, it is parsing it as a HTTP response rather than a JSON response. This is easily fixed by assigning your manager.responseSerializer to AFJSONResponseSerializer instead:
manager.responseSerializer = [AFJSONResponseSerializer serializer];
You'll find that you won't need to create an NSDictionary from the response - upon success it should come through as an NSDictionary object already.
Check out the AFNetworking 2.0 migration guide. It's a very handy read and will make you aware of what to look out for in the future.
