iOS 및 WatchKit에서 이미지 tintColor를 변경하는 방법

iOS 및 WatchKit에서 이미지 tintColor를 변경하는 방법

"theImageView"라는 UIImageView가 있는데 아래 왼쪽 검은 색 하트와 같은 단일 색상 (투명한 배경)으로 UIImage를 사용합니다. iOS 7+ 탐색 막대 아이콘에 사용 된 색조 방법에 따라 iOS 7 이상에서이 이미지의 색조 색상을 프로그래밍 방식으로 변경하려면 어떻게해야합니까?

Apple Watch 앱의 WatchKit에서도이 방법을 사용할 수 있습니까?

---

iOS
iOS 앱의 경우 Swift 3 또는 4에서

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

스위프트 2 :

theImageView.image = theImageView.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
theImageView.tintColor = UIColor.redColor()

한편, 최신 Objective-C 솔루션은 다음과 같습니다.

theImageView.image = [theImageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
[theImageView setTintColor:[UIColor redColor]];

---

Watchkit
Apple Watch 앱용 WatchKit 에서 템플릿 이미지 의 색조 색상을 설정할 수 있습니다 .

1. WatchKit 앱에서 자산 카탈로그에 이미지를 추가하고 속성 관리자에서 이미지 세트가 템플릿 이미지로 렌더링되도록 설정해야합니다. iPhone 앱과 달리 현재 WatchKit Extension에서 템플릿 렌더링을 코드로 설정할 수 없습니다.
2. 앱의 인터페이스 빌더에서 WKInterfaceImage에 사용되도록 해당 이미지를 설정하십시오.
3. 'theImage'라는 WKInterfaceImage에 대해 WKInterfaceController에 IBOutlet을 작성하십시오.

그런 다음 Swift 3 또는 4에서 색조 색상을 설정하려면

theImage.setTintColor(UIColor.red)

스위프트 2 :

theImage.setTintColor(UIColor.redColor())

그런 다음 Objective-C에서 색조 색상을 설정하려면

[self.theImage setTintColor:[UIColor redColor]];

템플릿 이미지를 사용하고 색조를 적용하지 않으면 WatchKit 앱의 전역 색조가 적용됩니다. 전역 색조를 설정하지 않으면 theImage템플릿 이미지로 사용할 때 기본적으로 밝은 파란색으로 표시됩니다.

트릭을 수행해야하는 범주는 다음과 같습니다.

@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

그래서 당신은 할 것입니다 :

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

Swift에서을 사용 하여이 작업을 수행해야했습니다 extension.

나는 내가 한 일을 나눌 것이라고 생각했다.

extension UIImage {
    func imageWithColor(color1: UIColor) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
        color1.setFill()

        let context = UIGraphicsGetCurrentContext() as CGContextRef
        CGContextTranslateCTM(context, 0, self.size.height)
        CGContextScaleCTM(context, 1.0, -1.0);
        CGContextSetBlendMode(context, CGBlendMode.Normal)

        let rect = CGRectMake(0, 0, self.size.width, self.size.height) as CGRect
        CGContextClipToMask(context, rect, self.CGImage)
        CGContextFillRect(context, rect)

        let newImage = UIGraphicsGetImageFromCurrentImageContext() as UIImage
        UIGraphicsEndImageContext()

        return newImage
    }
}

용법:

theImageView.image = theImageView.image.imageWithColor(UIColor.redColor())

스위프트 4

extension UIImage {
    func imageWithColor(color1: UIColor) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
        color1.setFill()

        let context = UIGraphicsGetCurrentContext()
        context?.translateBy(x: 0, y: self.size.height)
        context?.scaleBy(x: 1.0, y: -1.0)
        context?.setBlendMode(CGBlendMode.normal)

        let rect = CGRect(origin: .zero, size: CGSize(width: self.size.width, height: self.size.height))
        context?.clip(to: rect, mask: self.cgImage!)
        context?.fill(rect)

        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return newImage!
    }
}

용법:

theImageView.image = theImageView.image?.imageWithColor(color1: UIColor.red)

iOS

Interface Builder에서이를 수행하기위한 솔루션, keyPath에서 templateImage 매개 변수 설정 및 IB에서 색조 색상 선택

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
    }
}

}

Swift에서 확장 기능 활용 :-

extension UIImageView {
    func changeImageColor( color:UIColor) -> UIImage
    {
        image = image!.withRenderingMode(.alwaysTemplate)
        tintColor = color
        return image!
    }
}

   //Change color of logo 
   logoImage.image =  logoImage.changeImageColor(color: .red)

UIButton 이미지 틴팅

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)

iOS 13 이상에서는 간단하게 사용할 수 있습니다

let image = UIImage(named: "Heart")?.withRenderingMode(.alwaysTemplate)
if #available(iOS 13.0, *) {
   imageView.image = image?.withTintColor(UIColor.white)
}

이제 Duncan Babbage 응답을 기반으로 한이 방법을 사용합니다.

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

지우기 버튼을 교체 할 이미지가있는 경우 Swift 3에서이를 사용할 수 있습니다.

func addTextfieldRightView(){

    let rightViewWidth:CGFloat = 30

    let viewMax = self.searchTxt.frame.height
    let buttonMax = self.searchTxt.frame.height - 16

    let buttonView = UIView(frame: CGRect(
        x: self.searchTxt.frame.width - rightViewWidth,
        y: 0,
        width: viewMax,
        height: viewMax))

    let myButton = UIButton(frame: CGRect(
        x: (viewMax - buttonMax) / 2,
        y: (viewMax - buttonMax) / 2,
        width: buttonMax,
        height: buttonMax))

    myButton.setImage(UIImage(named: "BlueClear")!, for: .normal)

    buttonView.addSubview(myButton)

    let clearPressed = UITapGestureRecognizer(target: self, action: #selector(SearchVC.clearPressed(sender:)))
    buttonView.isUserInteractionEnabled = true
    buttonView.addGestureRecognizer(clearPressed)

    myButton.addTarget(self, action: #selector(SearchVC.clearPressed(sender:)), for: .touchUpInside)

    self.searchTxt.rightView = buttonView
    self.searchTxt.rightViewMode = .whileEditing
}

코드 및 인터페이스 빌더에서도 사용할 수있는 서브 클래스 :

@implementation TintedImageView

- (instancetype)initWithFrame:(CGRect)frame {
    self = [super initWithFrame:frame];
    if (self) {
        [self setup];
    }
    return self;
}

- (instancetype)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {
        [self setup];
    }
    return self;
}

-(void)setup {
    self.image = [self.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
}

@end

이것은 내 UIImage 확장이며 이미지에 changeTintColor 함수를 직접 사용할 수 있습니다.

extension UIImage {

    func changeTintColor(color: UIColor) -> UIImage {
        var newImage = self.withRenderingMode(.alwaysTemplate)
        UIGraphicsBeginImageContextWithOptions(self.size, false, newImage.scale)
        color.set()
        newImage.draw(in: CGRect(x: 0.0, y: 0.0, width: self.size.width, height: self.size.height))
        newImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return newImage
    }

    func changeColor(color: UIColor) -> UIImage {
        let backgroundSize = self.size
        UIGraphicsBeginImageContext(backgroundSize)
        guard let context = UIGraphicsGetCurrentContext() else {
            return self
        }
        var backgroundRect = CGRect()
        backgroundRect.size = backgroundSize
        backgroundRect.origin.x = 0
        backgroundRect.origin.y = 0

        var red: CGFloat = 0
        var green: CGFloat = 0
        var blue: CGFloat = 0
        var alpha: CGFloat = 0
        color.getRed(&red, green: &green, blue: &blue, alpha: &alpha)
        context.setFillColor(red: red, green: green, blue: blue, alpha: alpha)
        context.translateBy(x: 0, y: backgroundSize.height)
        context.scaleBy(x: 1.0, y: -1.0)
        context.clip(to: CGRect(x: 0.0, y: 0.0, width: self.size.width, height: self.size.height),
                 mask: self.cgImage!)
        context.fill(backgroundRect)

        var imageRect = CGRect()
        imageRect.size = self.size
        imageRect.origin.x = (backgroundSize.width - self.size.width) / 2
        imageRect.origin.y = (backgroundSize.height - self.size.height) / 2

        context.setBlendMode(.multiply)
        context.draw(self.cgImage!, in: imageRect)

        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return newImage!
    }

}

이와 같은 사용 예

let image = UIImage(named: "sample_image")
imageView.image = image.changeTintColor(color: UIColor.red)

그리고 당신은 changeColor이미지 색상을 변경하기 위해 변경 기능을 사용할 수 있습니다
