iOS performSelectorOnMainThread with multiple arguments

Question

I would like to perform a selector on the main thread from another thread, but the selector has multiple arguments, similar to this:

-(void) doSomethingWith:(int)

Answer 1

You'll need to use a NSInvocation

Create the object, set the target, selector and arguments.
Then, use

[ invocationObject performSelectorOnMainThread: @selector( invoke ) withObject: nil, waitUntilDone: NO ];
