截图 UIImageView 我只需要图像 IOS [英] Taking Screenshot of UIImageView I need only image IOS

问题描述

在我的 IOS 应用程序中，我正在截取 UIImageView 的屏幕截图.它非常完美，如附件照片所示.但是在这里，我采用了 UIImageView content mode aspect fit .我用过这个代码.

In my IOS App I am taking screenshot of UIImageView. It's very perfect as shown in attachment Photo. But here, I have taken UIImageView content mode aspect fit . I've used this code.

func captureView() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(imageView.bounds.size, false,UIScreen.mainScreen().scale)//add this line

        let context: CGContextRef = UIGraphicsGetCurrentContext()!
        self.backView.layer.renderInContext(context)
        let img: UIImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return img
    }

我只需要 Image 的快照，而不是 ImageView.帮我解决这个问题.

Simply I need the snapshot of Image, Not the ImageView. Help me into this.

推荐答案

试试这个代码:

func captureView() -> UIImage() {

    UIGraphicsBeginImageContext(YourimageView.frame.size)
    YourimageView.layer.renderInContext(UIGraphicsGetCurrentContext()!)
    let img = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    UIImageWriteToSavedPhotosAlbum(img, nil, nil, nil)
    return img
}
