AFJSONRequestOperation returns null response in iOS - json

Question

I am facing 1 problem while using AFJSONRequestOperation. My API Client is as follows
#import <Foundation/Foundation.h>
#import "AFHTTPClient.h"
#import "AFJSONRequestOperation.h"
#interface MyAPIClient : AFHTTPClient
+ (MyAPIClient *)sharedAPIClient;
#end
// .m file
#import "MyAPIClient.h"
#implementation MyAPIClient
+ (MyAPIClient *)sharedAPIClient {
static MyAPIClient *sharedClient = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedClient = [[MyAPIClient alloc] initWithBaseURL:[NSURL URLWithString:kBASE_URL]];
});
return sharedClient;
}
- (id)initWithBaseURL:(NSURL *)url {
self = [super initWithBaseURL:url];
if (!self) {
return nil;
}
[self registerHTTPOperationClass:[AFJSONRequestOperation class]];
[self setDefaultHeader:CONTENT_TYPE_FIELD value:CONTENT_TYPE_JSON_VALUE];
self.parameterEncoding = AFJSONParameterEncoding;
return self;
}
#end
Now when I request with following code it returns me "null" response
NSDictionary *params = [[NSDictionary alloc]initWithObjectsAndKeys:userName,#"email",password,#"password",nil];
NSMutableURLRequest *request = [[MyAPIClient sharedAPIClient] requestWithMethod:#"POST" path:#"login" parameters:params];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
{
NSDictionary *dictResponse = (NSDictionary*)JSON;
DLog(#"Login Success JSON: %#",JSON);
if (block) {
block(YES,nil);
}
}failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
DLog(#"Login Error:- %#",error);
if (block) {
block(NO,error);
}
}];
[operation start];
But when I use AFHTTPRequestOperation it reurns me correct output with logged in used info
NSURL *loginUrl = [NSURL URLWithString:kBASE_URL];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:loginUrl];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
userName,#"email",password,#"password",nil];
NSMutableURLRequest *request = [httpClient requestWithMethod:#"POST" path:#"login" parameters:params];
//Notice the different method here!
AFHTTPRequestOperation *operation = [httpClient HTTPRequestOperationWithRequest:request
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"Raw data Response: %#", responseObject);
NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
NSLog(#"Converted JSON : %#", jsonArray);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error){
NSLog(#"Error: %#", error);
}];
//Enqueue it instead of just starting it.
[httpClient enqueueHTTPRequestOperation:operation];
My server returns JSON response.
What is the problem in above code? Why AFJSONRequestOperation returns null response while
AFHTTPRequestOperation returns me correct response ? Any kind of help is appreciated. Thanks in advance
