FaceAwareFill

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
