How to take photo continuously using XLabs - ios

Question

Currently I'm developing a cross-platform app using Shared Library that able to take photos. I'm using XLabs.Forms V2.0.5782 package to do this app. I successfully developed this simple app but it only allows me to take one picture at a time.
I messed around with the codes and I managed to take multiple pictures but the problem is, the camera will be closed when I clicked 'Use Photo' and reopen again to take the next photo. What I wanted is, when I clicked 'Use Photo', the camera will reopen on the spot instead of closing and reopen.
Here's the code I did to take multiple pictures but I know it is not the right way to do it. It is in button clicked event.
IDevice device = Resolver.Resolve<IDevice>();
IMediaPicker media = device.MediaPicker;
//More codes here
async void TakePicture(object sender, System.EventArgs e)
{
var options = new CameraMediaStorageOptions()
{
PercentQuality = 50,
DefaultCamera = CameraDevice.Rear,
MaxPixelDimension = 250
};
var cancel = false;
while (!cancel)
{
await media.TakePhotoAsync(options).ContinueWith(t =>
{
if (t.IsFaulted) //If there's an error when taking photos
{
DisplayAlert("Error", "An error occurred when taking photo.\nPlease try again.", "OK");
}
else if (t.IsCanceled) //When the user click 'Cancel'
{
cancel = true;
}
else //When the user click 'Use Photo' - Here's the part where the camera will close and reopen until user click 'Cancel'
{
var img = ImageSource.FromStream(() => t.Result.Source);
picList.Add(img);
}
});
}
if (picList.Count > 0)
{
scrollParent.IsVisible = true;
imageScroll.Children.Clear();
foreach (var pl in picList)
{
var image = new Image()
{
Source = pl,
HeightRequest = 150,
HorizontalOptions = LayoutOptions.Start,
Aspect = Aspect.AspectFit,
Margin = new Thickness()
{
Right = 10
}
};
imageScroll.Children.Add(image);
}
}
}
Is it possible for me to take multiple pictures with XLabs.Forms and is there a proper way? I've search everywhere but found nothing about this. Any help will be much appreciated. Thanks!
Note:
I'm using Visual Studio for Mac Version Preview 9 (7.0 build 2943)
I've only tested on iPhone running iOS 10.2. Have not tested on Android device yet
Here's a gif showing an example of my app. I think this will make you guys have a better understanding of what I want and what is happening
Please note that 3 photos are taken in this example. The camera opens up four times. After taking each photo, I clicked 'Use Photo' on the bottom right and when the camera open on the 4th time, I clicked 'Cancel' on the bottom left to stop the loop
Thank you!
