In my project I tried to add two things:
But when I tried to test my app in a real device the app doesn't show any permission, and when I chose the camera the app exit without error message in the log console?
For the info.plist I use this two line:
<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) camera use</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>$(PRODUCT_NAME) photo use</string>
And add a photo I use this code:
@objc func addNewPerson(){
let picker = UIImagePickerController()
let ac = UIAlertController(title: "Choose image", message: nil, preferredStyle: .actionSheet)
let camera = UIAlertAction(title: "Camera", style: .default){
[weak self] _ in
if UIImagePickerController.isSourceTypeAvailable(.camera) {
picker.allowsEditing = false
picker.delegate = self
picker.sourceType = .camera
self?.present(picker,animated: true)
}else{
let alert = UIAlertController(title: "Warning", message: "You don't have camera", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self?.present(alert, animated: true, completion: nil)
}
}
ac.addAction(camera)
let galerie = UIAlertAction(title: "Photo library", style: .default){
[weak self] _ in
picker.allowsEditing = true
picker.delegate = self
self?.present(picker,animated: true)
}
ac.addAction(galerie)
ac.addAction(UIAlertAction(title: "Cancel", style: .cancel))
present(ac,animated: true)
}
Thank you.
in your addNewPerson()
method before showing the alert you should check if the user already granted access to his Camera you can do that by :
if AVCaptureDevice.AVCaptureDevice.authorizationStatus(AVMediaTypeVideo) == AVAuthorizationStatus.Authorized {
// Already Authorized
} else {
AVCaptureDevice. requestAccess(AVMediaTypeVideo, completionHandler: { (granted: Bool) -> Void in
if granted == true {
// User granted
} else {
// User rejected
}
})
}
Just to mention, in iOS 11 camera access is not required to use the UIImagePicker
Here is copy-pasted fragment from rickster's post .
in iOS 11, UIImagePickerController runs as a separate process from your app. That means:
Your app can't see the user's whole Photos library — it gets read-only access just for whichever asset(s) the user chooses in the image picker. Because of (1), your app doesn't need the standard privacy authorization for Photos library access. The user explicitly chooses a specific asset (or multiple) for use in your app, which means the user is granting your app permission to read the asset(s) in question.
