REFrostedViewController

iOS 7 style blurred view controller that appears on top of your view controller.

Requirements

• Xcode 5 or higher
• Apple LLVM compiler
• iOS 6.0 or higher
• ARC

Demo

Build and run the REFrostedViewControllerExample project in Xcode to see REFrostedViewController in action.

Installation

CocoaPods

The recommended approach for installating REFrostedViewController is via the CocoaPods package manager, as it provides flexible dependency management and dead simple installation. For best results, it is recommended that you install via CocoaPods >= 0.23.0 using Git >= 1.8.0 installed via Homebrew.

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods
$ pod setup

Change to the directory of your Xcode project:

$ cd /path/to/MyProject
$ touch Podfile
$ edit Podfile

Edit your Podfile and add REFrostedViewController:

platform :ios, '6.0'
pod 'REFrostedViewController', '~> 1.0.1'

Install into your Xcode project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file)

$ open MyProject.xcworkspace

Please note that if your installation fails, it may be because you are installing with a version of Git lower than CocoaPods is expecting. Please ensure that you are running Git >= 1.8.0 by executing git --version. You can get a full picture of the installation details by executing pod install --verbose.

Manual Install

All you need to do is drop REFrostedViewController files into your project, and add #include "REFrostedViewController.h" to the top of classes that will use it.

Example Usage

self.menuViewController = [[REFrostedViewController alloc] init];
[self.menuViewController presentFromViewController:self animated:YES completion:nil];

Customization

You can customize the following properties of REFrostedViewController:

@property (strong, readwrite, nonatomic) UIColor *blurTintColor;
@property (assign, readwrite, nonatomic) CGFloat blurRadius;
@property (assign, readwrite, nonatomic) CGFloat blurSaturationDeltaFactor;
@property (assign, readwrite, nonatomic) CGFloat threshold;
@property (assign, readwrite, nonatomic) NSTimeInterval animationDuration;

The blur algorithm comes from WWDC 2013's session 208, "What's New in iOS User Interface Design".
