Hi, I have a class (JCDataCollector) which I use to collect a large amount of data from the users machine. JCDataCollector has a publicly-accessible method named "collectData:usingFile:shouldLogOutput:". This method is very resource-intensive, and I would like to move it onto its own thread. So far, I have been able to call the method using NSThread's "detachNewThreadSelector:toTarget:withObject:" functionality. However, I cannot find a way to return the data collected in my "collectData:usingFile:shouldLogOutput:" method to the object which originally detached the thread selector. Also, my "collectData:usingFile:shouldLogOutput:" method takes multiple arguments, but NSThread's "detachNewThreadSelector:toTarget:withObject:" only allows one parameter to be passed. Short of storing all the parameters in an NSArray, is there any way to pass multiple parameters while calling "detachNewThreadSelector:toTarget:withObject:"?
Dictionaries are very useful for passing parameters, as you can name them and access them in arbitrary order.
If you make it mutable, it solves your other problem too - just place the results in the same dictionary. The originating thread can retain a reference to it so you have a shared object through which the threads are able to communicate.
