Xamarin Studio iOS程序集错误

Question

After I updated my Xamarin Studio (iOS) it gives me this error when trying to build/debug.

I ain't got no clue how to fix this, would appreciate some help

Error:

The type 'MonoTouch.UIKit.UIView' is defined in an assembly that is not referenced. 
Consider adding a reference to assembly 'monotouch, Version=0.0.0.0, 
Culture=neutral, PublicKeyToken=null'

I am using "AlexTouch.MBProgressHUD.dll" and I have added it to my usings.

Answer 1

The public key token of monotouch.dll changed in Xamarin.iOS 6.2 (it's not null anymore).

You'll need to recompile bindings (or assemblies) that refers to monotouch.dll or use the tool ( from this thread ) to update them.
