UIImagePickerController:didFinishPickingMediaWithInfo 未被调用 [英] UIImagePickerController: didFinishPickingMediaWithInfo not being called

问题描述

希望你们一切顺利.想知道是否有人可以帮助我理解为什么 Xcode 不能和我一起玩......

Hope you're all doing well. Wondered if anyone could help me understand why Xcode fails to play nice with me....

我已将代码分解为以下部分，以便我从 UIImagePicker 中选择个人资料照片:

I have broken the code into sections below in order to allow me to select a profile photo from UIImagePicker:

1. 作品:为 ImagePicker & 分配委托类导航控制器
2. 工作:实例化 UIImagePicker 变量
3. 作品:加载 ImagePickerViewController 并启用选择图像
4. FAILS:添加了用于使用 UIImagePicker 关闭和完成拾取的附加功能，但两者都没有被调用?我做错了什么?

提前致谢！

class ProfileVC: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
var imagePicker: UIImagePickerController!

<小时>

override func viewDidLoad() {
    super.viewDidLoad()

    imagePicker = UIImagePickerController()
    imagePicker.delegate = self
}

<小时>

@IBAction func selectPhotoPressed(sender: UITapGestureRecognizer) {
    if UIImagePickerController.isSourceTypeAvailable(.PhotoLibrary) {
        self.imagePicker.sourceType = .PhotoLibrary
    } else {
        self.imagePicker.sourceType = .Camera
    }
    imagePicker.allowsEditing = true
    imagePicker.mediaTypes = [kUTTypeImage as String]
    self.presentViewController(imagePicker, animated: true, completion: nil)
}

<小时>

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

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo image: UIImage, editingInfo: [String : AnyObject]?) {
    headerView.profilePhoto.contentMode = .ScaleAspectFill
    headerView.profilePhoto.image = image
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    uploadImage(image)
}

推荐答案

好的，我现在似乎可以运行了，感谢您帮助确定代码是古老的 ;) 以下是现在运行的内容:

OK I seem to have it working now, thanks for your help in identifying that the code was ancient ;) Here is what now runs:

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    let image = info[UIImagePickerControllerOriginalImage] as? UIImage
    headerView.profilePhoto.contentMode = .ScaleAspectFit
    headerView.profilePhoto.image = image
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    uploadImage(image!)
}
