Hi
Maybe, you could write your code as following:
$ macirb --simple-prompt
>> framework 'AppKit'
=> true
>> range = Pointer.new(NSRange.type)
=> #<Pointer:0x40122e760>
>> range.assign NSMakeRange(0,1)
=> #<NSRange location=0 length=1>
>> str = NSAttributedString.alloc.initWithString("hello")
=> hello{
}
>> str.attribute(NSUnderlineStyleAttributeName, atIndex:0, effectiveRange:range)
=> nil
Cheers.
