Background turns light grey instead of blurred?

[JulesMoorhouse]

Hi,

I have exactly the same issue that I have with MZFormSheetController.

https://github.com/m1entus/MZFormSheetController/issues/182

I've adding my viewcontroller to my navigation controller programmatically, rather than with my storyboard, although I don't know why that should make a difference.

I now have.

Any ideas?

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];

nav.navigationBarHidden = YES;

MZFormSheetPresentationController *formSheetController = 
    [[MZFormSheetPresentationController alloc] 
     initWithContentViewController:nav];
formSheetController.shouldApplyBackgroundBlurEffect = YES;
formSheetController.blurEffectStyle = UIBlurEffectStyleExtraLight;
// To set blur effect color, but uglty animation
//    formSheetController.backgroundColor = [[UIColor redColor] colorWithAlphaComponent:0.8];

[self presentViewController:formSheetController animated:YES completion:nil];

I fixed this problem with MZFormSheetController maybe the same applies here.

I'd like to re-open this as it doesn't matter what I do I have the same problem.

If I set shouldApplyBackgroundBlurEffect = YES I get a light grey color, if I don't set it, it respects the blurEffectStyle value. I'm using iOS 8.

Please help me.

:(

Thanks in advance.

Since MZFormSheetPresentationController relies on UIVisualEffectView to show blurred background, you're getting that grey background because your device (real or emulated) does not support blurring (see http://stackoverflow.com/questions/26411227/detect-if-device-properly-displays-uivisualeffectview).

Thanks for explanation. I am closing it.

it's still the case for me. my Base SDK is 9.2 and targeting 8.0, but still only have a dimming light instead of blurry effect

[m1entus]

You will never get blur using UIVisualEffect on ipad 2 and iphone 4, ios version does,t matter because this devices don't support blur...

I used marypopin instead, think it may provide its own blur effect for those devices, can't recall

[m1entus]

Yes it is possible using snapshot and blurry it but i don't wont implement it only for those devices

[JosephZZ]

i just found out it was a problem else where in my own code. sorry for the trouble and thanks for trying to help!

@JosephZZ what was the problem?

[JosephZZ]

@natanrolnik I missed a line of code that the document specifies. It was setting some value to true I think.

When you turn on option in iPhone Settings called: Reduce Transparency for better contrast and readability you're gonna loose the blur effects.
