Option to blur UIViewController background

[jyounus]

Hey,

What would be the best way to implement blur? Not the blur effect on the Action Sheet, but instead a blur effect for the View Controller that's still visible behind it all. I want to lightly blur the content behind my View Controller when I show the action picker.

You mean like this?

Actually it's pretty easy to get something like that. You just have to subclass RMActionController, make the property backgroundView publicly available and overwrite the getter for this property. The getter may look like follows:

- (UIView *)backgroundView {
    if(!_backgroundView) {
        UIVisualEffect *effect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
        UIVisualEffectView *effectView = [[UIVisualEffectView alloc] initWithEffect:effect];
        self.backgroundView = effectView;

        _backgroundView.translatesAutoresizingMaskIntoConstraints = NO;

        UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(backgroundViewTapped:)];
        [_backgroundView addGestureRecognizer:tapRecognizer];
    }

    return _backgroundView;
}

If that's what you want, I'm also thinking about integrating this functionality into RMActionController. Seems to be a good idea :)...

Update: Added the option to the RMActionController git Repo

I was thinking of a blur where you have more control over the blur amount. Something more like a custom gaussian blur with a radius you can change.

I implemented something but not into your library. I just show a blurred view before showing the picker and hide it on dismiss. I use a library called "FXBlurView" for it.

Thanks for your help tho. What you've done will probably be useful for other users in the future I guess. :)
