profileImageView。image = theImageView.image!.withRenderingMode(.alwaysTemplate) profileImageView。tintColor = uiccolor .green

OR

首先在图像资产中选择特定图像，然后选择红色作为模板而不是默认，然后写行。 profileImageView。tintColor = uiccolor .green

用于着色UIButton的图像

let image1 = "ic_shopping_cart_empty"
btn_Basket.setImage(UIImage(named: image1)?.withRenderingMode(.alwaysTemplate), for: .normal)
btn_Basket.setImage(UIImage(named: image1)?.withRenderingMode(.alwaysTemplate), for: .selected)
btn_Basket.imageView?.tintColor = UIColor(UIColor.Red)

在故事板和图像资产中。你也可以改变这两个:

更新渲染模式为模板图像

更新视图中的色调颜色。

let navHeight = self.navigationController?.navigationBar.frame.height;
let menuBtn = UIButton(type: .custom)
menuBtn.frame = CGRect(x: 0, y: 0, width: 45, height: navHeight!)     
menuBtn.setImage(UIImage(named:"image_name")!.withRenderingMode(.alwaysTemplate), for: .normal)        
menuBtn.tintColor = .black

现在我使用基于Duncan Babbage response的方法:

+ (UIImageView *) tintImageView: (UIImageView *)imageView withColor: (UIColor*) color{
    imageView.image = [imageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
    [imageView setTintColor:color];
    return imageView;
}

profileImageView。image = theImageView.image!.withRenderingMode(.alwaysTemplate) profileImageView。tintColor = uiccolor .green
