Description Boris Scheiman 2013-11-19 05:24:30 UTC
Using UIBarButtonItem w/ the title constructor (ie, new
UIBarButtonItem("blah", Style.Plain, etc...)) w/ a null title results in an
ArgumentNullException, when the following is valid ObjC:

[[UIBarButtonItem alloc] initWithTitle:nil style:UIBarButtonItemStylePlain
target:nil action:nil];

Why is this? Bug or feature?
Comment 1 Boris Scheiman 2013-11-19 05:27:04 UTC
Forgot to mention: using the empty constructor and setting properties allows for a null title (setting all required properties but title and titleview)
Comment 2 Sebastien Pouliot 2013-11-19 08:52:38 UTC
It's an oversight, the [NullAllowed] attribute is missing from the bindings. I'll add them (looks like `UITabBarItem` suffers from the same) for future releases. Thanks for spotting (and reporting) this!

This fix is planned to be released with Xamarin.iOS 7.0.6, which should hit the beta channel before December 23rd.
