【中文标题】iOS Swift 3 UIImagePickerController 崩溃【英文标题】：iOS Swift 3 UIImagePickerController crash 【发布时间】：2016-10-12 09:47:45 【问题描述】：我将项目升级到 Swift 3，但在线上发生了崩溃（在项目中的各个点/viewControllers）：
present(picker, animated: true, completion: nil)
在函数中：
@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)
控制台中的崩溃消息：
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>
我环顾四周，确实发现在 info.plist 中有 NSPhotoLibraryUsageDescription 和 NSCameraUsageDescription 可以解决问题（UIImagePickerController in Swift 3 和 UIImagePickerController crashes app | Swift3, Xcode8），但它不适合我。我做了清理和构建，重新启动了 xCode，重新启动了 Mac，等等。
值得指出的是，我的控制台在启动时显示：
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.
但根据这个无关紧要的线程https://forums.developer.apple.com/thread/63254
我的班级有代表：
class PersonalSettingsVC: UIViewController, UITextFieldDelegate, UITextViewDelegate, UINavigationControllerDelegate, UIImagePickerControllerDelegate
非常感谢任何帮助
【问题讨论】：
设置两个委托 => UIImagePickerControllerDelegate, UINavigationControllerDelegate 您好，两位代表在场。感谢您的回答。 @PeterdeVries 您的应用程序从哪个点崩溃... 您需要授予相机访问权限。 @seggy 应用程序在“按下按钮”后崩溃。我也试过： present(picker, animated: true) print("succes") ，它没有出现在控制台中。我在 info.plist 中提供了相机访问权限，我是否需要在 VC 中也这样做？ 【参考方案1】：好的，所以我想通了。 （我生命中的 3 天）即使我将隐私密钥放在我的 info.plist 中，应用程序实际上并没有访问/识别它们。所以我必须去***应用程序->目标->“MY_APP”->信息并将它们也放在那里。之后，它跑了。 （Jecky、Seggy 和 KAR 的解决方案很棒，所以我投了赞成票）。显然是一个错误，希望它可以帮助某人。

【参考方案2】：对我来说，在 info.plist 中添加以下内容后它起作用了 隐私 - 相机使用说明 $(PRODUCT_NAME) 相机使用
【讨论】：
【参考方案3】：试试我的代码 它是用相机拍照或从库中选择。只需给 UIImagePickerControllerDelegate,UINavigationControllerDelegate
在 Info.plist 文件中设置属性 隐私 - 照片库使用说明：允许照片
@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)

我非常感谢您的回答，并且确实在另一个威胁中遇到了您之前的回答。它崩溃了：'presentViewController(:animated:completion:)' 已使用 swift 3.0 重命名为'present(:animated:completion:)' 好的，我去看看 同样的崩溃，但在“从相机胶卷中选择”。很棒的实现，喜欢它！ 给我您的电子邮件 ID。我会把demo转发给你【参考方案4】：为您的 swift 3.0 代码试试这个，
@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 )
它将在您的应用程序中显示选择器，并且可以完美运行。
希望它能解决你的问题。

好的，现在这很好，因为我也在 swift 2.2 中给出了答案，这就是我评论它的原因??? @PeterdeVries 检查我更新的答案。它对我有用。 @PeterdeVries 好的。没问题。检查并提供反馈【参考方案5】：在 Swift 3 上试试这个。
@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
【讨论】：
嗨，试过了，.camera 什么都不做（模拟器中没有相机），当我将它更改为 photoLibrary 时，同样的崩溃。 目前我在我的应用程序中使用此代码，并且在 ios 10 中也支持，为什么你投反对票.. 给你任何错误的指示？ 只是让你知道，我感谢你的所有帮助，我不会在这里投票给任何人 @PeterdeVries 好的，请检查我的代码，我在 swift 3 中将其用于相机胶卷【参考方案6】：尝试将NSCameraUsageDescription 键添加到您的 PrettyApp-Info.plist 文件中并带有一些文本描述。
