AFNetworking response for "key": "\u0001" Not recieved - ios

Question

For my AFNetworking request I expect such "key": "\u0001" response but i am not getting rather I get "key": "". I tried following multiple stack questions but didn't work for me.
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setTimeoutInterval:15];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"application/json"];
manager.securityPolicy.allowInvalidCertificates = true;
manager.securityPolicy.validatesDomainName = false;
[manger.requestSerializer setValue:#"Application/json" forHTTPHeaderField:#"Accept"];
manger.responseSerializer = [AFHTTPResponseSerializer serializer];
[manger GET:url parameters:nil progress:nil success:^(NSURLSessionTask *operation, id responseObject){
NSLog(#"Response REST AP loaded %#", responseObject);
NSMutableDictionary *response = responseObject;
}
It worked in String format when i wrote this line of code
NSString* newStr = [[NSString alloc] initWithData:responseObject encoding:NSASCIIStringEncoding];
But now i don't know how to make it to NSDictionary, i also tried converting this to NSDictionary
NSData *webData = [newStr dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:webData options:0 error:&error];
This did not work.
Can anyone guide me proper steps how to achieve my expected output.
Thank You

Answer 1

I suggest that you should check responseObject type, for example:
if ([[responseObject class] isSubclassOfClass:[NSDictionary class]]) {
// return responseObject because this is a dictionary
}
else {
NSError *error = nil;
NSString* newStr = [[NSString alloc] initWithData:responseObject encoding:NSASCIIStringEncoding];
NSData *webData = [newStr dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
return [NSJSONSerialization JSONObjectWithData:webData options:0 error:&error];
}

Answer 2

NSDictionary* responseDict = [self dataObject:responseData];
use this and then call this method
- (id) dataObject:(NSData*)data
{
return [ NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
}

Try another ways:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setTimeoutInterval:15];
manager.securityPolicy.allowInvalidCertificates = true;
manager.securityPolicy.validatesDomainName = false;
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager GET:requestURL parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Response REST AP loaded %#", responseObject);
}
