I am using code from http://osmorphis.blogspot.com/2009/05/multiple-buttons-on-navigation-bar.html to implement multiple buttons in the navigation bar.

Right now, I solve it like this: - (void)someMethod { // some code } And this: [self performSelector:@selector(someMethod) withObject:nil afterDelay:0.1]; It works, but I have to create a new method every time.
