如何使动作表按钮转到另一页？

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        self.label.text = @"Destructive Button Clicked";
    } else if (buttonIndex == 1) {
        self.label.text = @"Other Button 1 Clicked";
    } else if (buttonIndex == 2) {
        self.label.text = @"Other Button 2 Clicked";
    } else if (buttonIndex == 3) {
        self.label.text = @"Cancel Button Clicked";
    }

    /**
     * OR use the following switch statement
     * Suggested by Colin =)
     */

    /*
    switch (buttonIndex) {
        case 0:
            self.label.text = @"Destructive Button Clicked";
            break;
        case 1:
            self.label.text = @"Other Button 1 Clicked";            
            break;
        case 2:
            //???????????
            self.label.text = @"Other Button 2 Clicked";   <<<<<< WHAT DO I PUT HERE???***
            //???????????
            break;
        case 3:
            self.label.text = @"Cancel Button Clicked";
            break;
     }
     */
}
