pushviewcontroller animation is slow/choppy

Question

I push a ViewController which contains not too many views, UIScrollView which contains 10 views inside, I have a singleton ViewController

Answer 1

Swift: If you are applying shadow on any view etc then you can also try below code for this.

view.layer.shouldRasterize = true
view.layer.rasterizationScale = UIScreen.main.scale

Answer 2

I had this problem, and it was because of old code in the pushed view controller, which caused the view to "fade in", setting the alpha to 0 on viewWillAppear and setting the alpha to 1 on viewDidAppear.

I removed the old code that did this, and the push worked fine.

-(void)viewWillAppear {
    self.view.alpha = 0; //REMOVE THIS LINE
}
