颜色着色UIButton图像

I noticed that when I place a white or black UIImage into a UISegmentedControl it automatically color masks it to match the tint of the segmented control. I thought this was really cool, and was wondering if I could do this elsewhere as well. For example, I have a bunch of buttons that have a uniform shape but varied colors. Instead of making a PNG for each button, could I somehow use this color masking to use the same image for all of them but then set a tint color or something to change their actual color?

设置好框架后

NSArray *arr10 =[NSArray arrayWithObjects:btn1,btn2,nil];
for(UIButton *btn10 in arr10)
{
CAGradientLayer *btnGradient2 = [CAGradientLayer layer];
btnGradient2.frame = btn10.bounds;

btnGradient2.colors = [NSArray arrayWithObjects:
                       (id)[[UIColor colorWithRed:151.0/255.0f green:206.0/255.5 blue:99.0/255.0 alpha:1] CGColor],
                       (id)[[UIColor colorWithRed:126.0/255.0f green:192.0/255.5 blue:65.0/255.0 alpha:1]CGColor],
                       nil];
[btn10.layer insertSublayer:btnGradient2 atIndex:0];

}

Swift 4与customType:

let button = UIButton(frame: aRectHere)
    let buttonImage = UIImage(named: "imageName")
    button.setImage(buttonImage?.withRenderingMode(.alwaysTemplate), for: .normal)
    button.tintColor = .white

以上都不适合我，因为点击后色调被清除。我必须使用

button.setImageTintColor(Palette.darkGray(), for: UIControlState())

如果你有一个带有背景图像的自定义按钮。您可以设置您的按钮的色调颜色和覆盖以下图像。

在资产中选择你想设置色调的按钮背景。

在图像的属性检查器中设置渲染值为“Template image”

现在当你setbutton时。tintColor = UIColor。红色“您”按钮将以红色显示。

Xamarin的。iOS (c#):

UIButton messagesButton = new UIButton(UIButtonType.Custom);
UIImage icon = UIImage.FromBundle("Images/icon.png");
messagesButton.SetImage(icon.ImageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), UIControlState.Normal);
messagesButton.TintColor = UIColor.White;
messagesButton.Frame = new RectangleF(0, 0, 25, 25);
