Now the size changes is working:
dot.frame = CGRectMake(dot.frame.origin.x, dot.frame.origin.y, imgNormal.size.width, imgNormal.size.height);

A bit late I know! But I’ve just updated the original code in the post to include the fix from Steve. Thanks.

You can change the size doin’g this:
- (void)updateDots {

if (imgCurrent || imgNormal) {
NSArray *dotViews = self.subviews;
for (int i = 0; i < dotViews.count; ++i) {
UIImageView *dot = [dotViews objectAtIndex:i];
dot.image = (i == self.currentPage) ? imgCurrent : imgNormal;
dot.frame = CGRectMake(0, 0, imgNormal.size.width, imgNormal.size.height);
}
}
}

This code is very good.
Also works on iOS 4.0, but you have to use Steve’s last comment. Thanks guys!

OMG Ignore what I said above. Unless you like making hacky code. Instead your answer lies in overriding one more method.

Put this in your implementation.

- (void)endTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event {
[super endTrackingWithTouch:touch withEvent:event];
[self updateDots];
}

My solution to the problem Greg Maletic found -where the page controllers revert back to white/grey after the page control is directly clicked- is to call setImageNormal and setImageCurrent from within function that gets invoked. It’s hacky, but it works.

[pgControl addTarget:self action:@selector(pageControlDidChange) forControlEvents:UIControlEventValueChanged];

Then, inside pageControlDidChange, in addition to the normal behavior you may be looking for, call the setImageNormal and setImageCurrent again

Where do the dot images go?

This is not using any private APIs.
