Question

请告诉我使用选择器视图获取图像路径的方法。

    func addImage(sender: AnyObject){

    picController.allowsEditing = false
    picController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(picController, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
    self.dismissViewControllerAnimated(true, completion: nil)
    titleImageView.image = image
   //Get the path of the image selected
   // print(path)
}

我想打印图像的路径。谢谢

Answer 1

工作代码

    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
    self.titleImageView.image = image
    let url: NSURL = editingInfo.valueForKey("UIImagePickerControllerReferenceURL") as! NSURL
    print(url.absoluteString)
    self.dismissViewControllerAnimated(true, completion: nil)
}

您正在使用的UIImagePickerController API通过委派提供对UIImage对象的引用。使用此UIImage引用，您可以将图像写入文件并使用该路径。要获得对库中图像资源的引用，您需要使用不同的委托回调：didFinishPickingMediaWithInfo。只需从信息词典UIImagePickerControllerReferenceURL获取路径。

有关详细信息，请参阅Apple的documentation。
