如何從代碼設置動畫樣式？

Question

我用setViewControllers方法替換導航控制器中的視圖。 但我不喜歡過渡的外觀。如何在使用以下代碼時設置動畫樣式？

UIViewController *newVC = [self.storyboard instantiateViewControllerWithIdentifier:@"SuccessScreen"]; 
    NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:[[self navigationController] viewControllers]]; 
    [viewControllers removeLastObject]; 
    [viewControllers addObject:newVC]; 
    [[self navigationController] setViewControllers:viewControllers animated:YES];

CATransition *yourAnimation=...; 
[self.navigationController.view.layer addAnimation:yourAnimation forKey:nil] 
[[self navigationController] setViewControllers:viewControllers animated:NO];
