从 UIImagepickercontroller 选择后如何保存图像

Question

我正在使用 Swift 和 Xcode 构建一个 iOS 应用程序 6. 我已经实现了从 UIImagePickerController 选择图像并设置到 UIImageView 的功能。

这是我的代码 select 来自 UIImagePickerController 的图像：

@IBAction func loadImageButtonTapped(sender: UIButton) {
        imagePicker.allowsEditing = false
        imagePicker.sourceType = .PhotoLibrary
        // imagePicker.sourceType = .Camera
        //imagePicker.sourceType = .SavedPhotosAlbum

        presentViewController(imagePicker, animated: true, completion: nil)
    }


    // MARK: - UIImagePickerControllerDelegate Methods
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
        if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
           // imageView.contentMode = .ScaleAspectFit
            imageView.image = pickedImage

        }

        dismissViewControllerAnimated(true, completion: nil)
    }

    func imagePickerControllerDidCancel(picker: UIImagePickerController) {
        dismissViewControllerAnimated(true, completion: nil)
    }

现在我正在寻找存储此图像的最佳方式，当用户再次访问应用程序时，我可以获取图像并在 uiimageview 中显示。

有人能帮我实现这个吗？

感谢帮助！

提前致谢！

试试这个。

let imageData: NSData = UIImageJPEGRepresentation(yourImage, 0.9)
let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
let destinationPath = documentsPath.stringByAppendingPathComponent("filename.jpg")
imageData.writeToFile(destinationPath, atomically: false)

然后稍后检索图像：

let loadedImage = UIImage(contentsOfFile: destinationPath)
