swift 3的目的

theImageView.image = theImageView.image!.withRenderingMode(.alwaysTemplate)
theImageView.tintColor = UIColor.red

另外，对于以上的答案，在iOS 13及以后有一个干净的方法

let image = UIImage(named: "imageName")?.withTintColor(.white, renderingMode: .alwaysTemplate)

这里有一个类别应该可以做到这一点

@interface UIImage(Overlay)
@end

@implementation UIImage(Overlay)

- (UIImage *)imageWithColor:(UIColor *)color1
{
        UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
        CGContextRef context = UIGraphicsGetCurrentContext();
        CGContextTranslateCTM(context, 0, self.size.height);
        CGContextScaleCTM(context, 1.0, -1.0);
        CGContextSetBlendMode(context, kCGBlendModeNormal);
        CGRect rect = CGRectMake(0, 0, self.size.width, self.size.height);
        CGContextClipToMask(context, rect, self.CGImage);
        [color1 setFill];
        CGContextFillRect(context, rect);
        UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        return newImage;
}
@end

所以你会这样做:

theImageView.image = [theImageView.image imageWithColor:[UIColor redColor]];

与迅速

let commentImageView = UIImageView(frame: CGRectMake(100, 100, 100, 100))
commentImageView.image = UIImage(named: "myimage.png")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
commentImageView.tintColor = UIColor.blackColor()
addSubview(commentImageView)

iOS

解决方案从接口生成器，设置templateImage参数在keyPath和选择您的色调颜色从IB

extension UIImageView {

// make template image with tint color
var templateImage: Bool {
    set {
        if newValue, let image = self.image {
            let newImage = image.withRenderingMode(.alwaysTemplate)
            self.image = newImage
        }
    } get {
        return false
    }
}

}

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
