Description Chris Hardy [MSFT] 2011-11-09 06:37:10 UTC
Allow a user to create a IBOutletCollection (Along with IBAction and IBOutlets) and have that correspond back to a typed array of selected object.

See http://www.bobmccune.com/2011/01/31/using-ios-4s-iboutletcollection/ for an explanation of IBOutletCollection and this is what the Xcode side looks like http://screencast.com/t/c0NGOavR7Qn (Multi-select buttons, click and drag to the .h file and select the bottom item in the drop down of Outlet, Action and Outlet Collection).

Michael, would you be able to give me a rough idea of what would be involved in implementing this? Would the right approach be:

public class OutletCollectionAttribute : OutletAttribute
    public string ItemType { get; set; }

Then add handling to sync this to/from xcode correctly?

This functionality is very useful. IBOutletCollection is used in many XIB files to aggregate groups of controls into arrays. Implementing this allows more reuse across environments and eases porting other projects. In particular when a collection of controls represents exclusive choices, or when it is desirable to operate on the controls as a group, fast iteration is commonly used to operate across the collection.

I would also like to see Outlet Collections added.

Another vote for IBOutletCollection support.  Thanks.

Implemented. This will be part of Xamarin Studio 4.0.3
