I couldn’t believe that just a rebuild with Xcode 4.2 messed up this. This is a reasonable explanation. And now it works!

It is the fifth problem I have to solve because of iOS 5. At least it has a razonable explanation.

Just to make any one know, because I didn’t find any explication.
I had an object which I need to change width and X position bounds. When I set new bounds, it changes X to -0. Crazy! I solved it setting bounds twice, first time for new X position, and second time for new Width.

First Code:
> bounds.size.width = bounds.size.width + 40;
> bounds.origin.x = ((bounds.size.width) * index;
> pagingScrollView.bounds = bounds;

Solution code:
> bounds.size.width = bounds.size.width + 40;
> pagingScrollView.bounds = bounds;
> bounds.origin.x = ((bounds.size.width) * index;
> pagingScrollView.bounds = bounds;

I hope it can help.

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[self.nextResponder touchesBegan: touches withEvent:event];
}

iOS5 / Xcode 4.2 seems to need to register the touchesBegan before it will allow touchesEnded to exist.

So your full UIScrollView subclass .m will contain the following:

- (id)initWithFrame:(CGRect)frame {
return [super initWithFrame:frame];
}

// This fixes it for iOS 5 / Xcode 4.2
- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[self.nextResponder touchesBegan:touches withEvent:event];
}

- (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
if (!self.dragging){
[self.nextResponder touchesEnded:touches withEvent:event];
}
else
[super touchesEnded:touches withEvent:event];
}

With my best,

i have a map with a rectangular slider that indicates the current position of the scrollview on the screen. i could update the position in the super view’s gameloop if i could get the position somehow. everything i’ve tried only updates the slider after any touch is finished.

thanks!

Good Job!!
