Xamarin iOS Image Tint Color

Question

I want to use an template image which is black and use the tintColor of this image to set the color and to have only one image.

Then I put template image in asset And I try to change the color by :

object.TintColor = UIColor.Blue;

But it doesn't work, it still black

Can someone help me please ?

Thanks

Are you updating it on the UIThread? – Brandon Minnick Nov 22 '17 at 20:50 — Brandon Minnick, Nov 22 '17 at 20:50

You must set the image rendering mode to AlwaysTemplate in order to have the TintColor affect your UIImage, otherwise it will display image as is. It helps control the color of Image to any color you wish to set, with having a single image in Resources or xcassets.

Following Code should Help you.

imgViewObject.Image = imgViewObject.Image.ImageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate);
imgViewObject.TintColor = UIColor.Blue;

We can also set Rendering Mode from xcassets as shown in following image:

Oh my god, it works ! But why I need to put ImageWithRenderingMode in code while I put it in assets ? – Nov 22 '17 at 22:45

Can this be set in AppDelegate.cs for system wide iOS usage? – juicebyjustin Jul 23 '22 at 15:04
