UpdateTouchesOnIOS updates the touch state on iOS . This should be called with touch handlers of UIViewController like this : - ( GLKView * ) glkView { return ( GLKView * ) [ self . view viewWithTag : 100 ] ; } - ( void ) updateTouches : ( NSSet * ) touches { for ( UITouch * touch in touches ) { if ( touch . view ! = [ self glkView ] ) { continue ; } CGPoint location = [ touch locationInView : [ self glkView ]] ; // Exported function for UpdateTouchesOnIOS YourGameUpdateTouchesOnIOS ( touch . phase ( int64_t ) touch location . x location . y ) ; } } - ( void ) touchesBegan : ( NSSet * ) touches withEvent : ( UIEvent * ) event { [ self updateTouches : touches ] ; } - ( void ) touchesMoved : ( NSSet * ) touches withEvent : ( UIEvent * ) event { [ self updateTouches : touches ] ; } - ( void ) touchesEnded : ( NSSet * ) touches withEvent : ( UIEvent * ) event { [ self updateTouches : touches ] ; } - ( void ) touchesCancelled : ( NSSet * ) touches withEvent : ( UIEvent * ) event { [ self updateTouches : touches ] ; } The coodinate x / y is in point . UpdateTouchesOnIOS can be called even before Start is called . UpdateTouchesOnIOS is concurrent - safe . For more details see https : // github . com / hajimehoshi / ebiten / wiki / iOS .
