In order send request for getting data, you have to add key in info.plist as follow :
And just update your code as below :
NSError *error;
NSDictionary *dicData = [[NSDictionary alloc] initWithObjectsAndKeys:#"user123", #"username", #"pass1234", #"password", #"pass1234", #"cpassword", #"0123456789", #"mobile", #"User", #"firstname", #"Name", #"lastname", #"register", #"action", nil];
NSLog(#"parameter=%#",dicData);
// NSURLComponents *components = [NSURLComponents componentsWithString:#"http://followerlikes.com/app_appoint/json/?action=register"];
//
// NSMutableArray *queryItems = [NSMutableArray array];
// for (NSString *key in dicData) {
// [queryItems addObject:[NSURLQueryItem queryItemWithName:key value:dicData[key]]];
// }
// components.queryItems = queryItems;
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://followerlikes.com/app_appoint/json/?action=register"]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
NSData *postData = [NSJSONSerialization dataWithJSONObject:dicData options:0 error:&error];
[request setHTTPBody:postData];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(#"Data : %#",data);
NSLog(#"RESPONSE : %#",response);
NSLog(#"ERROR : %#",error);
NSString *strRes = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"%#",strRes);
NSError *resultError;
NSDictionary *dicResult = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&resultError];
NSLog(#"RESPONSE DICT : %#", dicResult);
dispatch_async(dispatch_get_main_queue(), ^ {
if (error !=nil) {
NSLog(#"ERROR : %#",error.description);
NSLog(#"ERROR : %#",error.localizedDescription);
}
else {
// completion(dicResult);
}
});
}];
[task resume];
