I have to pass number (int) to my next method and I amd trying with next code but with no success:

int myNumber = 45;
[self performSelector:@selector(startNewThing) withObject:myNumber afterDelay:0.5f];

How can I pass number through performSelector?

    Here are the changes I’d make to your snippet:

    NSNumber *myNumber = [NSNumber numberWithInteger:45];
[self performSelector:@selector(startNewThing:) withObject:myNumber afterDelay:0.5f];

    Note that I placed a colon after -startNewThing. That is so the method can accept myNumber as an argument. (This is assuming that -startNewThing: really does take an argument.) And since we’ve changed myNumber from a scalar to an object, you’d need to make the appropriate changes to -startNewThing:.
