I have a problem with objective-c code that handles openning camera to take a picture the code is injected as native code inside codename one
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
NSArray *mediaTypes = [[NSArray alloc]initWithObjects:(NSString *)kUTTypeImage, nil];
imagePicker.mediaTypes = mediaTypes;
imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
[[[[[UIApplication sharedApplication] delegate] window] rootViewController] presentViewController:imagePicker animated:YES completion:nil];
}else{
[self showAlert:@"No Camera Privilege On This Device"];
}
the problem is when the above code is executed on iOS-11 ,I get null pointer exception from codenameone without asking for camera permission unlike iOS-12 the code works perfectly
the permission are added in the codenamesettings
codename1.arg.ios.NSPhotoLibraryAddUsageDescription=The App uses the Photo Library to save Images downloaded from News
codename1.arg.ios.NSCameraUsageDescription=The App uses the Camera for Video Chat support
codename1.arg.ios.NSPhotoLibraryUsageDescription=The App uses the Photo Library to save Images downloaded from News
is there anything that can be done to handle the issue on iOS11

appreciate the help
Regards,
thanks for all of your help , the problem as stated was only on iOS11 , and the reason for that if I present any viewcontroller with animated:Yes and I changed how to call the view controller by adding the following code
dispatch_queue_t _serialQueue = dispatch_queue_create("x.y.z", DISPATCH_QUEUE_CONCURRENT);
dispatch_sync(_serialQueue, ^{
self.filePath=param;
[self showForm];
});
and the showForm : just take a copy of the old viewcontroller and present the new one like this [condition was used to wait for the camera to finish picking and saving the file to gallery] :
-(void)showForm{
condition = [[NSCondition alloc] init];
self.parentViewController = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
[self.parentViewController.view setUserInteractionEnabled:NO];
destinationViewController = [[ViewController alloc] initWithValues:self.filePath andCondition:condition andChoice:@"Camera"];
[[[[[UIApplication sharedApplication] delegate] window] rootViewController] presentViewController:destinationViewController animated:NO completion:nil];
[condition lock];
[condition wait];
self.filePath = [(ViewController*)destinationViewController getImagePath];
[self.parentViewController.view setUserInteractionEnabled:YES];
[condition unlock];
}
I hope that would help any one who needs it
Regards,
