iOS Swift 3 UIImagePickerController 崩溃 [英] iOS Swift 3 UIImagePickerController crash

问题描述

我将项目升级到 Swift 3 并且我在线上崩溃了(在项目中的各个点/viewControllers):

I upgraded project to Swift 3 and I am getting a crash on the line (at various points/viewControllers in the project) :

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:

in my in info.plist I have:

<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，确实看到在 info.plist 中有 NSPhotoLibraryUsageDescription 和 NSCameraUsageDescription 解决了这个问题(UIImagePickerController 在Swift 3 和 UIImagePickerController 崩溃应用程序 | 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.

I looked around and did see that having NSPhotoLibraryUsageDescription and NSCameraUsageDescription in info.plist solves the issue (UIImagePickerController in Swift 3 and UIImagePickerController crashes app | Swift3, Xcode8), but it doesn't for me. I did clean and build, restarted xCode, restarted Mac, etc.

值得指出的是，我的控制台在启动时说:

It might be worth pointing out that my console at startup says:

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. 

但根据这个线程无关紧要https://forums.developer.apple.com/thread/63254

but according to this thread that doesn't matter 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

推荐答案

好的，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，它们实际上并没有被应用程序访问/识别.所以我不得不去顶级应用程序 -> 目标 -> "MY_APP" -> 信息并将它们也放在那里.在那之后，它跑了.(来自 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，希望对某人有所帮助.

Ok, so I figured it out. (3 days of my life) Even though I put the Privacy keys in my info.plist, they were not actually accessed/ recognised by the app. so I had to go top level app -> Targets -> "MY_APP" -> info and put them there as well. after that, it ran. (Solutions from Jecky, Seggy and KAR were great, so I upvoted). obviously a bug, hope it helps someone.
