Hi guys! I want to try developing an app like Trapster, where users can report police control easy. I'm very new at iOs programming. I want the app to be like a map, and uses the Gps. When the user presses "report" a pin shows up at the spot where the person is. The "pin" will be valid for 2 hours and then disappear. I also want a push notification system. I want the user to have the opportunity to decide how many meters before they reaches the "pin" nearby before they get a notification. like " Police control "x" meters. Take it easy " Where should I start? I need some tutorials about how to make an app like this. Thank you!
