Problem in Xamarin.Forms Ios app

Hi Guys,
I'm facing problem with Xamarin.Forms Ios App.I'm getting this error.
Can any one help to get out of this issue.
System.Exception: Could not initialize an instance of the type 'MonoTouch.UIKit.UIImage': the native 'initWithContentsOfFile:' method returned nil.
It is possible to ignore this condition by setting MonoTouch.ObjCRuntime.Class.ThrowOnInitFailure to false.
