Answer 1

You do it easily as below,

-(void)aFunc {

Do Asynchronous A job...

while (A is not finished) {
// If A job is finished, a flag should be set. and the flag can be a exit condition of this while loop

// This executes another run loop.
[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];

}

Do things using the A's result.
