使用Swift 2.0将图像保存到照片库 [英] saving an image to photos library using Swift 2.0

问题描述

我上面的红色突出显示了问题。当我拍照并按下使用照片时，我不会将我拍​​摄的照片保存到iPad上的相册中。我已经看过其他方式，但我是iOS开发的初学者，我不确定如何解决这个问题。我有时也会得到一个sigabrt错误。

I'm getting a problem highlighted in red above. When I take a picture and press use photo, it won't let me save the photo I took to the photo album on my iPad. I have looked at other ways but me being a beginner to iOS development, I'm unsure of how to fix this problem. I sometimes get a sigabrt error too.

推荐答案

您是否提供了完成选择器？

Have you provided the completion Selector?

...
UIImageWriteToSavedPhotosAlbum(imageView.image!, self, "image:didFinishSavingWithError:contextInfo:", nil) 
...



func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo:UnsafePointer<Void>) {
    if error == nil {
        let ac = UIAlertController(title: "Saved!", message: "Your altered image has been saved to your photos.", preferredStyle: .Alert)
        ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
        presentViewController(ac, animated: true, completion: nil)
    } else {
        let ac = UIAlertController(title: "Save error", message: error?.localizedDescription, preferredStyle: .Alert)
        ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
        presentViewController(ac, animated: true, completion: nil)
    }
}
