Answer 1

Use this -

for (UIView *v in self.pageViewController.view.subviews) {
    if ([v isKindOfClass:[UIScrollView class]]) {
        ((UIScrollView *)v).delegate = self;
    }
}

to implement this protocol : -(void)scrollViewDidScroll:(UIScrollView *)scrollView

and then use @xhist's code (modified) in this way

-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGPoint point = scrollView.contentOffset;

float percentComplete;
percentComplete = fabs(point.x - self.view.frame.size.width)/self.view.frame.size.width;
NSLog(@"percentComplete: %f", percentComplete);
}
