Crash on iOS when using Keyboard / Camera together by accident

Bug Reports
1

Issue: When using keyboard and camera, the user will sometimes engage both by accident. This leads to an application crash. Encountered in Preview and Release builds on iOS.

Platform: iOS (at least)

Encountered in Fuse: Version 0.33-0.37

Package: Fuse.Camera

I’m uploading a tiny app that reproduces the issue:

Steps to reproduce

Click on the TextInput and then immediately click on the “Camera” button.

Possible Fix

I changed ImagePicker.m openImagePickerWithSourceType to this:

-(BOOL)openImagePickerWithSourceType:(UIImagePickerControllerSourceType)type then:(DictionaryAction)a or:(Action)or
{
	if([UIImagePickerController isSourceTypeAvailable:type])
	{
		self.onPicture = a;
		self.onCancel = or;
		_imagePicker = [[UIImagePickerController alloc] init];
		_imagePicker.sourceType = type;
		[_imagePicker setDelegate:self];
		dispatch_async(dispatch_get_main_queue(), ^{
			[[self VC] presentViewController:_imagePicker animated:YES completion:^{ }];
		});
		return YES;
	}else{
		return NO;
	}
}

The crash seems to go away if using async rather than presenting immediately.
