I would like to use blocks, however I'm using the 10.5 SDK so as
far as I know blocks cannot be used. Is there a way to get
performSelectorOnMainThread to return a value? That would solve my
issue, because I could pass on the NSAttributedString to a method
on the main thread that figures out the size and all, then returns
the value.
Give performSelectorOnMainThread an object that has space for a
result value. In olden days this was called a parameter block.
