iOS Swift 3 UIImagePickerController崩潰

Question

我將項目升級到Swift 3，並且在行中崩潰（在項目中的各個點/ viewControllers處）：

present(picker, animated: true, completion: nil)

在函數中：

@IBAction func userImage(_ sender: AnyObject){
    print("button pressed")
    let picker = UIImagePickerController()
    picker.delegate = self
    picker.allowsEditing = false
    picker.sourceType = .photoLibrary
    present(picker, animated: true, completion: nil) // -> crashes here
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let image = info[UIImagePickerControllerOriginalImage] as! UIImage
    self.imageToPost.setImage(newImage, for: UIControlState())
    self.imageToPost.imageView?.contentMode = UIViewContentMode.scaleAspectFill
    picker.dismiss(animated: true, completion: nil)
}

控制台中的崩潰消息：

libsystem_kernel.dylib`__abort_with_payload:
0x11108d138 <+0>:  movl   $0x2000209, %eax          ; imm = 0x2000209

0x11108d14e <+22>: nop    
0x11108d14f <+23>: nop    

在我的info.plist中，我有：

<key>NSPhotoLibraryUsageDescription</key>
<string>$(PRODUCT_NAME) photo gallery use</string>
<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) camera use </string>
<key>NSMicrophoneUsageDescription</key>
<string>$(PRODUCT_NAME) microphone use</string>

我環顧四周，確實發現info.plist中包含NSPhotoLibraryUsageDescription和NSCameraUsageDescription解決了該問題（ Swift 3中的 UIImagePickerController和UIImagePickerController使app | Swift3，Xcode8崩潰 ），但這並不適合我。 我做了清理和構建，重新啟動了xCode，重新啟動了Mac等。

可能值得指出的是，我的控制台在啟動時說：

objc[11204]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x11a0d8910) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x119f02210). One of the two will be used. Which one is undefined. 

但是根據這個線程沒關系https://forums.developer.apple.com/thread/63254

我班有代表：

class PersonalSettingsVC: UIViewController, UITextFieldDelegate, UITextViewDelegate, UINavigationControllerDelegate, UIImagePickerControllerDelegate 

任何幫助深表感謝

Answer 1

好的，我知道了。 （生命中的3天）即使我將隱私密鑰放在了info.plist中，該應用程序實際上也並未對其進行訪問/識別。 因此，我必須轉到頂級應用程序->目標->“ MY_APP”->信息，並將其放置在該位置。 之后，它運行了。 （來自Jecky，Seggy和KAR的解決方案很棒，因此我投票贊成）。 顯然是一個錯誤，希望它能對某人有所幫助。

Answer 2

對我來說，在我在info.plist中添加以下內容后，它起作用了-相機使用說明$（PRODUCT_NAME）相機使用

Answer 3

試試我的代碼

用相機拍照或從圖庫中選擇。

只需給UIImagePickerControllerDelegate，UINavigationControllerDelegate

在Info.plist文件中設置屬性隱私-照片庫使用說明：允許照片

@IBAction func dsfsd(_ sender: AnyObject) {

        let actionSheetController: UIAlertController = UIAlertController(title: "Action Sheet", message: "Swiftly Now! Choose an option!", preferredStyle: .actionSheet)

        //Create and add the Cancel action
        let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .cancel) { action -> Void in
            //Just dismiss the action sheet
        }
        actionSheetController.addAction(cancelAction)
        //Create and add first option action
        let takePictureAction: UIAlertAction = UIAlertAction(title: "Take Picture", style: .default) { action -> Void in
            if(  UIImagePickerController.isSourceTypeAvailable(.camera))

            {
                let myPickerController = UIImagePickerController()
                myPickerController.delegate = self
                myPickerController.sourceType = .camera
                self.present(myPickerController, animated: true, completion: nil)
            }
            else
            {
                let actionController: UIAlertController = UIAlertController(title: "Camera is not     available",message: "", preferredStyle: .alert)
                let cancelAction: UIAlertAction = UIAlertAction(title: "OK", style: .cancel) { action -> Void     in
                    //Just dismiss the action sheet
                }

                actionController.addAction(cancelAction)
                self.present(actionController, animated: true, completion: nil)

            }
        }

        actionSheetController.addAction(takePictureAction)
        //Create and add a second option action
        let choosePictureAction: UIAlertAction = UIAlertAction(title: "Choose From Camera Roll", style: .default) { action -> Void in
            let myPickerController = UIImagePickerController()
            myPickerController.delegate = self;
            myPickerController.sourceType = UIImagePickerControllerSourceType.photoLibrary
            self.present(myPickerController, animated: true, completion: nil)
        }
        actionSheetController.addAction(choosePictureAction)

        //Present the AlertController
        self.present(actionSheetController, animated: true, completion: nil)

    }


    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {


        let image = info[UIImagePickerControllerOriginalImage] as! UIImage
        self.imgview.image = image

        self.dismiss(animated: true, completion: nil)
    }

Answer 4

試試Swift 3。

@IBAction func userImage(_ sender: AnyObject){
 if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {

            self.imagePicker.delegate = self
            self.imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary;
            self.imagePicker.allowsEditing = true

            self.present(self.imagePicker, animated: true, completion: nil)
            self.imagePicked.isUserInteractionEnabled = true

        }

}

Answer 5

嘗試此操作以獲取快速的3.0代碼，

 @IBAction func takePhoto(_ sender: UIButton) {
    var picker = UIImagePickerController()
    picker.delegate = self
    picker.allowsEditing = true
    picker.sourceType = .camera
    self.present(picker, animated: true, completion: { _ in })
}

@IBAction func selectPhoto(_ sender: UIButton) {
    var picker = UIImagePickerController()
    picker.delegate = self
    picker.allowsEditing = true
    picker.sourceType = .photoLibrary
    self.present(picker, animated: true, completion: { _ in })
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [AnyHashable: Any]) {
    var chosenImage = info[UIImagePickerControllerEditedImage]
    self.imageView!.image = chosenImage
    picker.dismiss(animated: true, completion: { _ in })
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    picker.dismiss(animated: true, completion: { _ in })
}

它將在您的應用中顯示選擇器，並且可以完美運行。

希望它能解決您的問題。

嘗試使用一些文本說明將NSCameraUsageDescription鍵添加到PrettyApp-Info.plist文件中。
