Multiple Image Picker Plugin Error

[dixitsoftware]

Hi, I am trying to use wymsee image picker plugin cordova to choose multiple images in my ionic project. I am able to do it successfully in android but I am unable to use it in iOS.. The error I am getting is :

ERROR: Plugin 'ImagePicker' not found, or is not a CDVPlugin. Check your plugin mapping in config.xml.

Due to the above error when I checked config.xml file mapping of image picker plugin is there,
I tried to remove and add the iOS in my project but no luck.. Please guide me to resolve this issue..

Thanks
