imageView点击 滑动事件：
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(done)];
[imageView addGestureRecognizer:tap];
-(void) done
{
int clickedIndex = 0;
for (int i = 0; i < [self.buttonArray count]; i++)
{
if (touchView == [self.buttonArray objectAtIndex:i])
clickedIndex = i;
}
if (clickedIndex < centerIndex)
{
for (int i = 0; i < centerIndex - clickedIndex; i++)
{
if ([self.buttonArray objectAtIndex:[self.buttonArray count] - 1] != nil)
{
[self.buttonArray insertObject:[self.buttonArray objectAtIndex:[self.buttonArray count] - 1] atIndex:0];
[self.buttonArray removeObjectAtIndex:[self.buttonArray count] - 1 ];
[self resetButtonFrame];
}
}
}
else if(clickedIndex > centerIndex)
{
for (int i = 0; i < clickedIndex - centerIndex; i++)
{
[self.buttonArray addObject:[self.buttonArray objectAtIndex:0]];
[self.buttonArray removeObjectAtIndex:0];
[self resetButtonFrame];
}
}
else
{
int index = 0;
for (int i = 0; i < [self.saveImageArray count]; i++)
{
if (touchView.image == [self.saveImageArray objectAtIndex:i])
index = i;
}
}
}
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
touchView = (UIImageView*)[touch view];
}
-(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint previousPoint = [touch previousLocationInView:self];
CGPoint currentPoint = [touch locationInView:self];
CGFloat x = currentPoint.x - previousPoint.x;
if (currentPointCompare.x == previousPoint.x && currentPointCompare.y == previousPoint.y) {
}else
{
if (x > 10)
{
[self.buttonArray insertObject:[self.buttonArray objectAtIndex:[self.buttonArray count] - 1] atIndex:0];
[self.buttonArray removeObjectAtIndex:[self.buttonArray count] - 1 ];
}else if(x < (-10))
{
[self.buttonArray addObject:[self.buttonArray objectAtIndex:0]];

}

}

}
子类的点击，滑动事件可通过self.nextResponder转到父类执行，如下：
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.nextResponder touchesBegan:touches withEvent:event];
}
-(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.nextResponder touchesMoved:touches withEvent:event];
}
