Face Aware Fill

This category applies Aspect Fill content mode to an image and if faces are detected it centers them instead of centering the image just by its geometrical center.

Example:

Installation

FaceAwareFill is available through CocoaPods, to install it simply add the following line to your Podfile:

pod "FaceAwareFill"

Usage

Import the category to your .m file or to your "prefix" file.

#import "UIImageView+UIImageView_FaceAwareFill.h"

Then AFTER setting the image property of a UIImageView do:

[imageView faceAwareFill];

That's all.
Enjoy!

Debugging

A red rectangle can optionally be displayed on faces for debugging.
To enable, add the following value to the preprocessor macros:

DEBUGGING_FACE_AWARE_FILL

Notes:

• You can change the CIDetectorAccuracy from low to high if it fails to detect faces but it will make the rendering slower :(
• BEWARE of this bug when running face detection on 64bit devices http://stackoverflow.com/questions/19018962/core-image-face-detection-broken-on-64-bit-ios
