implicit conversion of 'NSInteger' (aka 'int') to 'UIEvent *' is disallowed with ARC

Question

Here is my relevant code:

UITouch *touch;         
NSArray *touches = [NSArray arrayWithObject:touch];
//The statement below throw the LLVM compiler error
[self touchesMoved:[NSSet setWithArray:touches] withEvent:UIEventTypeTouches];

here is the declaration of touchesMoved:withEvent: method:

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;

Seems like I need to explicitly convert UIEventTypeTouches to UIEvent, how to fix that?

What are you trying to do? You can't call `touchesMoved:withEvent:` manually. You can implement it as a delegate method or override it in a `UIGestureRecognizer` subclass. — Desdenova, Jul 12 '13 at 13:54

The compiler is complaining because UIEventTypeTouches is an NSInteger (defined in an enum) and touchesMoved:withEvent: is expecting a UIEvent object. You can probably get away with just passing nil for the event param:

[self touchesMoved:[NSSet setWithArray:touches] withEvent:nil];
