How do you trigger a block after a delay, like -performSelector:withObject:afterDelay:?
...eter1 = 12;
float parameter2 = 144.1;
// Delay execution of my block for 10 seconds.
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 10 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
NSLog(@"parameter1: %d parameter2: %f", parameter1, parameter2);
});
