ios - 来自 UIImagePicker 的图像的 NSURL

Question

我正在尝试将手机中的图片上传到我的 Amazon S3 存储桶:

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!)
{
    var uploadReq = AWSS3TransferManagerUploadRequest()
    uploadReq.bucket = "bucketname";
    uploadReq.key = "testimage.png"
    uploadReq.body = image; //This line needs an NSURL
}

如何获取用户从 UIImagePickerController 中选择的图像的 NSURL？

Answer 1

虽然正杰的回答可能有效。我找到了一种更简单的方法:

    let fileURL = NSURL(fileURLWithPath: NSTemporaryDirectory().stringByAppendingPathComponent("imagetoupload"))
    let data = UIImagePNGRepresentation(image)
    data.writeToURL(fileURL!, atomically: true)
    uploadReq.body = fileURL
