iOS 10.3.1中的iOS CAMImagePickerCameraViewController崩溃
在ios 10.3.1更新后,我的应用程序开始崩溃。当我尝试使用摄像头拾取视频时,崩溃发生。该应用程序在较旧的ios版本(9.3.5和10.2.1)上运行良好。 崩溃日志显示正在崩溃的是CAMImagePickerCameraViewController:iOS 10.3.1中的iOS CAMImagePickerCameraViewController崩溃,ios,crash,uiimagepickercontroller,Ios,Crash,Uiimagepickercontroller,在ios 10.3.1更新后,我的应用程序开始崩溃。当我尝试使用摄像头拾取视频时,崩溃发生。该应用程序在较旧的ios版本(9.3.5和10.2.1)上运行良好。 崩溃日志显示正在崩溃的是CAMImagePickerCameraViewController: OS Version: iPhone OS 10.3.1 (14E304) Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Except

以下是我的代码摘录:
/// Presents the video selection/capture dialog
fileprivate func presentPickerController() {
// Request authorization to access photo library if not yet granted
PHPhotoLibrary.requestAuthorization { status in
guard status == .authorized else {
self.alert(.notPermittedToSelectVideos)
return
}
// Create the custom asset picker (to get multiple at once)
let assetsPickerController = DKImagePickerController()
assetsPickerController.defaultAssetGroup = .smartAlbumVideos
assetsPickerController.showsCancelButton = true
assetsPickerController.assetType = .allVideos
assetsPickerController.didSelectAssets = self.didSelectAssets
assetsPickerController.didCancel = self.didCancel
assetsPickerController.disableCaptureWhenSelected = true
assetsPickerController.createCaptureController = self.createCaptureController
self.assetsPickerController = assetsPickerController
DispatchQueue.main.async {
self.present(assetsPickerController, animated: true) {}
}
}
}
fileprivate func createCaptureController() -> UIViewController? {
let imagePickerController = UIImagePickerController()
imagePickerController.sourceType = .camera
imagePickerController.mediaTypes = [kUTTypeMovie as String]
imagePickerController.videoQuality = .typeHigh
imagePickerController.delegate = self
guard canCaptureVideo() else {
Logger.info?.message("Attempted to capture video when cannot capture video")
alert(.cantCaptureVideo)
return nil
}
guard permittedToCaptureVideo() else {
Logger.info?.message("Attempted to capture video when cannot capture video")
alert(.notPermittedToCaptureVideo)
return nil
}
guard permittedToCaptureAudio() else {
Logger.info?.message("Attempted to capture video when cannot capture audio")
alert(.notPermittedToCaptureAudio)
return nil
}
return imagePickerController
}
崩溃的控制器不是我的应用程序的一部分,我无法触摸它。有人知道如何解决这个问题吗?
CAMImagePickerCameraViewController的用途是什么?为什么它只在ios 10.3.1上崩溃,而在以前的版本上没有崩溃?我这里有一些类似的问题,我发现这是代理的问题 我的问题是viewController保留了一个对象,我将该对象的弱委托设置为viewController,当viewController被解除且该对象仍试图使用委托执行某些操作时,发生了崩溃 所以我认为弱引用出错了…不知道为什么会发生这种情况,但是可以通过向viewController dealloc方法添加代码blow来修复
-(无效)解除锁定{
self.assetsPickerController=nil
}
我们有完全相同的问题。你找到解决办法了吗?
