ios8 blur effect disappear

Question

Thanks for reading my question I had some trouble stabilizing the intensity of blur effect

I had a UIImageView with blur effect (Extralight) which covered the whole view as a background The intensity of the blur effect looked just fine But after I added items onto the storyboard the blur effect dimmed so much almost disappear

sorry i don't have enough reputation to upload pictures

anyone know what caused it, and how to solve?

Thank you very much!

override func viewDidLayoutSubviews() {                  
    // set bg image and blur         
    bg.image = UIImage(named: "my portrait")         
    var blurEffect = UIBlurEffect(style:      UIBlurEffectStyle.ExtraLight)         
    var blurView = UIVisualEffectView(effect:     blurEffect)         
    blurView.frame = bg.bounds                  
    bg.addSubview(blurView) 
}

Posting some code samples would be helpful. – bgilham May 23 '15 at 16:10 — bgilham, May 23 '15 at 16:10

I think I found the reason It is because the blur view is added under function ViewDidLayoutSubview So the blur is added multiple times That's the reason it's looks dimmer and dimmer
