So here I have a loop that creates a bunch of different squares on the screen, using an array, and I've added a gesture recognizer to detect for a pan. The thing is, I want to be able to smoothly slide over one object to the next, without lifting my finger. But, with my current code I have to lift my finger and slide over each object individually. Does anyone know how to make it so that I can smoothly slide my finger over each object, and have them perform their functions when they've been slid over? Here's my code:
int numby = [squareLocations count];
for (int i = 0; i < numby; i++)
{
NSValue *pointLocation = [squareLocations objectAtIndex:i];
CGPoint tmpPoint = [pointLocation CGPointValue];
UIImage *theSquare = [UIImage imageNamed:@"square.png"];
UIButton *squareButton = [[UIButton alloc] init];
squareButton = [UIButton buttonWithType:UIButtonTypeCustom];
squareButton.frame = CGRectMake(tmpPoint.x, tmpPoint.y, theSquare.size.width, theSquare.size.height);
squareButton.tag = *(&i);
[squareButton setImage:theSquare forState:UIControlStateNormal];
UIPanGestureRecognizer *slide = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
[squareButton addGestureRecognizer:slide];
[whereStuffActuallyHappens addSubview:squareButton];
}
}
- (void) handlePan:(UIPanGestureRecognizer *)slide {
[slide setTranslation:CGPointZero inView:slide.view];
NSInteger tag = slide.view.tag;
NSLog(@"Tag is: %i", tag);
[slide.view removeFromSuperview];
}
