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.
