Customise Position of UIPageControl

Question

I am using project from github as a reference.

project URL:

https://github.com/lephuocdai/iOSsample/tree/master/PageViewDemo

In this project i want to show the UIPageControl at top left position .

I tried setting the rect property of pageControl using CGRectMake() to some value ;But it shows always at bottom center

Answer 1

here s a very neat and 100% effective way to get to change the position of the pageControl

extension UIPageViewController {
  override open func viewDidLayoutSubviews() {
      super.viewDidLayoutSubviews()

      for subV in self.view.subviews {
          if type(of: subV).description() == "UIPageControl" {
              let pos = CGPoint(x: newX, y: newY)
              subV.frame = CGRect(origin: pos, size: subV.frame.size)
          }
      }
  }
}

The project uses a UIPageViewController to handle the display and movement through the content. You can supply data to that object so it displays a UIPageControl as you say. BUT you have no control over the display of that item, other than maybe some colour styling. If you want to position it, you'll need to implement you're own instance of UIPageControl and handle it's content, position and changes manually.
