iOS Swift 3 UIImagePickerController 崩溃

Question

我将项目升级到 Swift 3，但线路崩溃(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 info.plist 中包含 NSPhotoLibraryUsageDescription 和 NSCameraUsageDescription 解决了问题( 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 xCode、重新启动 Mac 等。

可能值得指出的是，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. 

但根据这个线程，这并不重要 https://forums.developer.apple.com/thread/63254

我的类(class)有代表:

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

非常感谢任何帮助

好吧，我明白了。 (我生命中的 3 天)即使我将隐私 key 放入我的 info.plist 中，但应用程序实际上并未访问/识别它们。所以我必须去顶级应用程序 ->目标 ->“MY_APP” ->信息并将它们也放在那里。之后，它就跑了。 (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，希望它对某人有帮助。
