[MacRuby-devel] programatic binding (undefined bind method on NSTextField)

[Alex Greif]

I am on 10.6.8
I tried with the 0.10 and the nightly build from 2011.9.27 and with both
versions I get a "false" for the following statements in the macruby irb

I have installed Xcode 3.2.4

Any Ideas why this does not work?


--------- 0.10 -------------
$ macirb
irb(main):001:0>
NSObject.alloc.init.respond_to?('bind:toObject:withKeyPath:options:')
NSObject.alloc.init.respond_to?('bind:toObject:withKeyPath:options:')
=> false


--------- installed nightly build ---------------
$ macruby --version
MacRuby 0.11 (ruby 1.9.2) [universal-darwin10.0, x86_64]
$ macirb
irb(main):001:0>
NSObject.alloc.init.respond_to?('bind:toObject:withKeyPath:options:')
NSObject.alloc.init.respond_to?('bind:toObject:withKeyPath:options:')
=> false
