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

When you're using iOS >= 4, you'd do this instead:

dispatch_async(dispatch_get_main_queue(), ^{
    [self doSomething:1 b:2 c:3 d:4 e:5];
});

That's like doing waitUntilDone:NO. If you want to wait until the method is finished, use dispatch_sync instead.
