// Top of .m // ... // Imports // Implementation #pragma mark - MapViewController @implementation MapViewController // STEP 3: Synthesize the set ivars @synthesize mapView, searchBar, results, requestData // STEP 4: Now you should be able to use them :) // NOTE: If you are using ARC - if you want to allocate a set variable to memory and persist it then do: results = [NSMutableArray array]; // from memory? // NOTE: If you are not using ARC: results = [[NSMutableArray alloc] init] // I only ever use @syntesize to connect the .h and .m - as I said I might be wrong but it has worked for me so far haha // If anyone else wants to correct me somewhere please do :) I'm keen to learn!
