Swift IOS: several buttons in one view controller, control the image view display in another view controller

I just want to use 30 buttons in one view controller(#1), and when I click one of them(e.g. Button1), the screen can jump to another view controller(2), and display picture1. When I go back to view controller(#1), and click Button 2, it can jump to view controller(#2) and display picture 2...etc. I can switch two view controller using segues, but how can I control the content of image view not in the same view controller? Thanks.

You need to use prepareForSegue method to set the variables in other controllers. in your second controller your attribute needs to be a public.

Objective-C

#pragma mark - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([[segue identifier] isEqualToString:@"YOURSEGUENAME"]) {

        secondControllerViewController * secController = [[secondControllerViewController alloc] init];
        [secController setImageName:@"imagenameTeste"];
    }

 }

Swift

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "yourSegue") {
        // pass data to next view
    }
}
