Alternative without GPUImage Framework

[HeyChristian]

This is an alternative to NOT using GPUImage Framework, this function can capture a screenshot and place the blur effect.

I added a "AMSmoothAlertView.m" this function to return the image with the effect.

#import "UIImage+ImageEffects.h"

-(UIImage *)blurredSnapshot
{
    // Create the image context
    UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, self.window.screen.scale);

    // There he is! The new API method
    [self drawViewHierarchyInRect:self.frame afterScreenUpdates:NO];

    // Get the snapshot
    UIImage *snapshotImage = UIGraphicsGetImageFromCurrentImageContext();

    // Now apply the blur effect using Apple's UIImageEffect category
    UIImage *blurredSnapshotImage = [snapshotImage applyDarkEffect];
    //applyLightEffect
    // Or apply any other effects available in "UIImage+ImageEffects.h"
    // UIImage *blurredSnapshotImage = [snapshotImage applyDarkEffect];
    // UIImage *blurredSnapshotImage = [snapshotImage applyExtraLightEffect];

    // Be nice and clean your mess up
    UIGraphicsEndImageContext();

    return blurredSnapshotImage;
}

i'll try it and integrate it if it works great ! (interested about performances, could be a solution) thank you for contributing !

It appears it's not a blur effect but a dark effect.

[HeyChristian]

has several highlights in the background, does not look bad with your alerviews
