Reset images selected without destroying the ImagePicker ViewController

[RamonGilabert]

You access the selected stack and remove all the images. Although ImagePicker is intended to keep reference for a while, in a composer for example, when you are building a post, and not be used as a general thing that you keep reference to. You can though.

let imagePickerController = ImagePickerController()
imagePickerController.stack.assets = []

Edit: You could also extend ImageStack and build a method to remove all the assets. That's up to you.

@RamonGilabert thanks! :)

Simply calling imagePickerController.stack.assets = [] doesn't refresh the existing UI elements (the old images are still showing as selected, the count still shows as x, etc...)

@olivierlesnicki just resetting assets won't work.
There is a method intended for that purpose:

 public func resetAssets(assetsArray: [PHAsset])

so, just try:

picker.stack.resetAssets([PHAsset]())

This design is related to some lower-level issues with property observers and notifications. Using the function I've provided the notification will be posted and all UI components should update their state automatically.

@olivierlesnicki did @richardoti's suggestion work for you?

[olivierlesnicki]

@zenangst haven't tried yet
