Hello all,

Could somebody help me a little bit with my issue below?

When I call the myFunction, images which I want to set to buttons appear after 2 sec simultaneously, not one by one with delay of 0.5 sec.

More info:

• generatedNumbers is array with four elements of NSNumber (4,1,3,2)
• buttons are set in UIView via IB and are tagged (1,2,3,4)

-(IBAction) myFunction:(id) sender {
int i, value;
for (i = 0; i<[generatedNumbers count]; i++) {
    value = [[generatedNumbers objectAtIndex:i] intValue];
    UIButton *button = (UIButton *)[self.view viewWithTag:i+1];
    UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:@"%d.png",value]];
    [button setImage:img forState:UIControlStateNormal];
    [img release];
    usleep(500000);
}   
}
