Flicker in UIPageViewController's views about ios-pdf-reader HOT 5 CLOSED

Hmm, nothing initially jumps out at me. Do you have a simple example repo of a PDFPageView in a UIPageViewController? PDFPageView is an internal class and wasn't intended to be used outside of the context of the framework.

I'll create a sample project. I use a similar implementation, so I swapped classes and got the same result.

BTW, has this issue in CoreGraphics been resolved meanwhile?

class PdfTiledLayer: CATiledLayer {
    override class func fadeDuration() -> CFTimeInterval {
        return 0.001 // Workaround
    }

    override func display() {
        //contents = nil  --> Stops flickering but causes blinking instead.
        super.display()
    }
}

I could pin down the part that's responsible for the issue mentioned above. It's this line:

contentScaleFactor = 1

Commenting out …

// contentScaleFactor = 1

… solves it. What's the implication not setting this property to one? Everything renders fine and quite fast now!

But having said that, if the commenting out the above code works for you in your implementation, then go for it!
