I can change tint colour on UIButton but not UIImage

I am playing around with tint colours on a UIImage and a UIButton.

On the UIButton (when the button type is set to System), I am able to set the tint colour of the UIButton in Xcode by going to Attributes Inspector -> View -> Tint

On UIImageView, I have set the same image, but when I go to the Attributes Inspector -> View -> Tint, the colour of the image does not change.

Why is the behaviour like this ? and how do I fix it ?

I am using iOS 7 and Xcode 5.1.1

Solution

  • Your image's rendering mode needs to be set to template and not original. To do this, you can call the -[UIImage imageWithRenderingMode:] method on your image and pass in UIImageRenderingModeAlwaysTemplate, then set your image view's image to the resulting image:

    yourImageView.image = [yourImage imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];

    Or, in Swift:

    yourImageView.image = yourImage.imageWithRenderingMode(.AlwaysTemplate)
