UIView+Blur

iOS8 support!!

Apple finally gave us a neat way to implement dynamic blurs with UIVisualEffectView.

This category supports both iOS8 and iOS7 (iOS7 with UIToolbar trick)

for iOS8 only, there's now a blurVibrancyBackground property onto which you must add UIViews that you want to take advantage of the UIVibrancyEffect effect. Please look at demo project for an example on how to use it.

How To Get Started

add UIView+Blur.h/.m to your project, then import .h file

#import "UIView+Blur.h"

Create your UIView and activate the blur

UIView* view = [[UIView alloc] initWithFrame:CGRectMake(100, 160, 100, 100)];    
[view enableBlur:YES];
[view setBlurTintColor:[UIColor redColor]];
[view setBlurTintColorIntensity:0.3f];

Here's what can be customized, (check the .h file for more explanations):

/* The UIToolbar/UIVisualEffectView(ios8) that has been put on the current view, use it to do your bidding */
@property (strong,nonatomic,readonly) UIView* blurBackground;

/* The UIVisualEffectView that should be used for vibrancy element, add subviews to .contentView (ios8 only) */
@property (strong,nonatomic,readonly) UIVisualEffectView* blurVibrancyBackground NS_AVAILABLE_IOS(8_0);

/* tint color of the blurred view */
@property (strong,nonatomic) UIColor* blurTintColor;

/* intensity of blurTintColor applied on the blur 0.0-1.0, default 0.6f */
@property (assign,nonatomic) CGFloat blurTintColorIntensity;

/* returns if blurring is enabled */
@property (readonly,nonatomic) BOOL isBlurred;

/* Style of Blur, remapped to UIViewBlurStyle typedef above */
@property (assign,nonatomic) UIViewBlurStyle blurStyle;

Requirements

No requirements, I've tested this project with iOS 7.1 & iOS 8.1

Any suggestions are welcome ! as I am looking to learn good practices, to understand better behaviors and Objective-C in general ! Thank you.
