Sample project

I have troubles with the latest 5.0.1 build and iOS 4.3. A call to
UITableView.MoveRow method throws NSInvalidArgumentException exception. This
happens with *4.3 devices/emulators only, 5.0 works perfectly*. That's
strange since moveRowAtIndexPath method signature didn't change since iOS
SDK 2.0.

Here is an exception stack trace:

-[UITableView moveRowAtIndexPath:toIndexPath:]: unrecognized selector sent
to instance 0x8299200
MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown.
Name: NSInvalidArgumentException Reason: -[UITableView

Comment 1 Sebastien Pouliot 2011-11-01 19:38:02 UTC
So 'moveRowAtIndexPath:toIndexPath:' [1] is new in iOS5 (and will fail in iOS4.x) but easily confused with 'tableView:canMoveRowAtIndexPath:' which is available since 2.0 [2]
