[英]iOS Swift 3 UIImagePickerController crash
我将项目升级到Swift 3,并且在行中崩溃(在项目中的各个点/ viewControllers处):
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

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>$(PRODUCT_NAME) microphone use</string>
我环顾四周,确实发现info.plist中包含NSPhotoLibraryUsageDescription和NSCameraUsageDescription解决了该问题( Swift 3中的 UIImagePickerController和UIImagePickerController使app | Swift3,Xcode8崩溃 ),但这并不适合我。 我做了清理和构建,重新启动了xCode,重新启动了Mac等。
可能值得指出的是,我的控制台在启动时说:
objc[11204]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x11a0d8910) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x119f02210). One of the two will be used. Which one is undefined.
但是根据这个线程没关系https://forums.developer.apple.com/thread/63254
我班有代表:
class PersonalSettingsVC: UIViewController, UITextFieldDelegate, UITextViewDelegate, UINavigationControllerDelegate, UIImagePickerControllerDelegate
任何帮助深表感谢
好的,我知道了。 (生命中的3天)即使我将隐私密钥放在了info.plist中,该应用程序实际上也并未对其进行访问/识别。 因此,我必须转到顶级应用程序->目标->“ MY_APP”->信息,并将其放置在该位置。 之后,它运行了。 (来自Jecky,Seggy和KAR的解决方案很棒,因此我投票赞成)。 显然是一个错误,希望它能对某人有所帮助。
对我来说,在我在info.plist中添加以下内容后,它起作用了-相机使用说明$(PRODUCT_NAME)相机使用
试试我的代码
用相机拍照或从图库中选择。
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)
}
试试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
}
}
尝试此操作以获取快速的3.0代码,
@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 })
}
它将在您的应用中显示选择器,并且可以完美运行。
希望它能解决您的问题。
尝试使用一些文本说明将NSCameraUsageDescription
键添加到PrettyApp-Info.plist文件中。
