Question

Is there a simple way to apply a CoreImage filter to the content of a view? For example make a view look blurry?

Answer 1

you can convert the UIView to UIImage and then apply CoreImage filters on it..

you can use the following code to convert it..

+ (UIImage *) imageWithView:(UIView *)view
{
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);
    [view.layer renderInContext:UIGraphicsGetCurrentContext()];

    UIImage * img = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return img;
}
