Is there a way I can

Answer 1

For iOS 13.0

Obj-C:

self.yourImageView.image = [self.yourImageView.image imageWithTintColor:[UIColor.redColor]];

Swift:

yourImageView.image = yourImageView.image.withTintColor(UIColor.red);

If the image comes from the Asset Catalog, you can change the rendering in the Attribute Inspector
