iOS Apply UIColor to UIImage


Use same UIImage with multiple theme base app by just applying UIColor to UIImage instance as following.

// *** Create an UIImage instance with RenderingMode AlwaysTemplate ***
UIImage *imgMenu = [[UIImage imageNamed:@"iconMenu"] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];

// *** Now Apply `tintColor` to `UIImageView` of UIImageView or UIButton and convert image in given color ***
[btn setImage:imgMenu forState:UIControlStateNormal]; // Set UIImage in UIButton.

[button.imageView setTintColor:[UIColor blueColor]]; // It changes image color of UIButton to blue color

Now lets say you want to do same with UIImageView then use following code

[imageView setImage:imgMenu]; // Assign UIImage to UIImageView
[imageView setTintColor:[UIColor greenColor]]; // Change imageview image color to green.
[imageView setTintColor:[UIColor redColor]]; // Change imageview image color to red.
