iphone - How to pass arguments when calling function with timer in objective c

Question

-(void)setX:(int)x andY:(int)y andObject:(Sprite*)obj
{
    [obj setPosition:CGPointMake(x,y)];
}

Now, I want to call above method, using following timer.

[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector() userInfo:nil repeats:NO];

What to set Here?

How to Pass arguments? (as per my knowledge - selector specifies only the method to invoke)

Answer 1

You'll need to used +[NSTimer scheduledTimerWithTimeInterval:invocation:repeats:] instead. By default, the selector used to fire a timer takes one parameter. If you need something other than that, you have to create an NSInvocation object, which the timer will use instead.
