Hello everyone how are you,
Guys i am working on an app and its really pisssing me out, the app is deployed in the device and runs nicely the first time when i use it but when i stop the execution of the app in the device and then try to run it the next time then the touch screen hangs up and i am left with a black screen and then i reinstall my app again.

In the viewDidLoad i am using the instance of MKMapView and showing the users current location thats all 

Please help me out
