Description rumination.xamarin 2011-08-18 23:05:48 UTC
I'm trying to do something like this:

CATransaction.Begin();
CATransaction.CompletionBlock = delegate {
  Console.WriteLine("CATransaction completed");
};
...
CATransaction.Commit();

But I get a crash when attempting to set the CompletionBlock property:

+[CATransaction setSetCompletionBlock::]: unrecognized selector sent to class 0x3202104

Unhandled Exception: MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown.  Name: NSInvalidArgumentException Reason: +[CATransaction setSetCompletionBlock::]: unrecognized selector sent to class 0x3202104

This is in MT 4.0.4.1.

I can duplicate the issue using the lastest MonoTouch code.
Comment 2 Sebastien Pouliot 2011-08-19 09:45:08 UTC
It's a typo and/or generator errors (prefix and suffix).

	[Export ("setSetCompletionBlock::")]

should be

	[Export ("setCompletionBlock:")]
