Requirements

UIImage-Helpers works on iOS 5.0+ version and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

  • Accelerate.framework
  • Foundation.framework
  • QuartzCore.framework

You will need LLVM 3.0 or later in order to build UIImage-Helpers.

Adding UIImage-Helpers to your project

Cocoapods

CocoaPods is the recommended way to add UIImage-Helpers to your project.

  • Add a pod entry for UIImage-Helpers to your Podfile:
pod 'UIImage-Helpers'
  • Install the pod(s) by running:
pod install

Source files

Alternatively you can directly add source files to your project.

  1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
  2. Open your project in Xcode, then drag and drop all files at UIImage-Helpers folder onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.

Usage

  • Make a blurred image with another image
#import "UIImage+Blur.h"
...

// jpeg quality image data
float quality = .00001f;

// intensity of blurred
float blurred = .5f;

NSData *imageData = UIImageJPEGRepresentation([self.imageViewNormal image], quality);
UIImage *blurredImage = [[UIImage imageWithData:imageData] blurredImage:blurred];
self.imageViewBlurred.image = blurredImage;
  • Take a screenshot
#import "UIImage+Screenshot.h"
...

UIImage *image = [UIImage screenshot];
self.imageView.image = image;
  • Generate a image with color
#import "UIImage+ImageWithColor.h"
...
UIColor *purpleColor = [UIColor colorWithRed:.927f green:.264f blue:.03f alpha:1];
UIImage *image = [UIImage imageWithColor:purpleColor];

[self.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
