iOS 获取storyboard:中的VC

//获取storyboard: 通过bundle根据storyboard的名字来获取我们的storyboard,        UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];              

  //由storyboard根据myView的storyBoardID来获取我们要切换的视图        UIViewController *myView = [story instantiateViewControllerWithIdentifier:@"myView"];              

  //由navigationController推向我们要推向的view        [self.navigationController pushViewController:myView animated:YES];
