How to change iphone CATiledLayer fadeDuration?

Question

I am working on an iphone application that displays tiled maps. I am currently using a CATiledLayer in a UIScrollView :

     MyTiledDelegate *delegate=[[MyTi         


        

Answer 1

You should subclass the CATiledLayer and return fadeDuration of 0 to disable fade-in:

@interface FastCATiledLayer : CATiledLayer
@end

@implementation FastCATiledLayer
+(CFTimeInterval)fadeDuration {
  return 0.0;
}
@end

I also had the problem with fade in animation not completing, what helped was to set the background color of the view to [UIColor clearColor]

Answer 2

Try subclassing and overriding the +fadeDuration accessor on the layer.

Answer 3

Or in Swift 4:

class CAFastTiledLayer: CATiledLayer {
    class func fadeDuration() -> CFTimeInterval {
        return 0.0 
    }
}
