Changing UIImage color

by

Since iOS 7, this is the most simple way of doing it.

Objective-C:

theImageView.image = [theImageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[theImageView setTintColor:[UIColor redColor]];

Swift 2.0:

theImageView.image = theImageView.image?.imageWithRenderingMode(.AlwaysTemplate) 
theImageView.tintColor = UIColor.magentaColor()

Swift 4.0:

theImageView.image = theImageView.image?.withRenderingMode(.alwaysTemplate) 
theImageView.tintColor = .magenta

Storyboard:

First configure the image as template ( on right bar – Render as) in your assets. Then the color of the image would be the tint color applied.
