I have a registration view controller which handles all the user input and calls a function in another class (wsClass) passing to it, that data as an NSDictionary.

Answer 1

Try this . This will work well.

-(void)loadDetails
{

NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {


    _allVehicleLocationsArray = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

    [self afterCompleteDoThis];


}] resume];


}

-(void)afterCompleteDoThis{

for (NSDictionary *vehicleDict in _allVehicleLocationsArray) {

    NSLog(@" PPP %@" , [vehicleDict valueForKey:@"vehicleType"]);

}
}
