iOS - 如何在故事板中将视图预加载到内存中？

Question

在XIB中它对我来说很好。

ThirdViewController *thirdVC = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];

// preload views to the memory
[thirdVC view];

// setup fromviews array and toviews array
NSArray *fromViews = [NSArray arrayWithObjects:self.imageView1, self.imageView2, self.label1, nil];
NSArray *toViews = [NSArray arrayWithObjects:thirdVC.imageView1, thirdVC.imageView2, thirdVC.label1, nil];

[self pushViewController:thirdVC fromViews:fromViews toViews:toViews duration:1.0];

但是当我在故事板中将视图预加载到内存中时，我不知道如何使用它。

UIStoryboard *sb = [UIStoryboard storyboardWithName:@"FourthVC" bundle:nil];
FourthVC *vc = [sb instantiateViewControllerWithIdentifier:@"FourthVC"];

NSArray *fromViews = [NSArray arrayWithObjects:self.imageView1, self.imageView2, self.label1, nil];

NSArray *toViews = [NSArray arrayWithObjects:vc.imageView1, vc.imageView2, vc.label1, nil];

[self pushViewController:vc fromViews:fromViews toViews:toViews duration:1.0];

任何人都可以建议我如何在故事板中预加载视图？

我得到了答案感谢@ Tj3n

 UIStoryboard *sb = [UIStoryboard storyboardWithName:@"FourthVC" bundle:nil];
 FourthVC *vc = [sb instantiateViewControllerWithIdentifier:@"FourthVC"];   

// preload views to the memory
 [vc view];

 NSArray *fromViews = [NSArray arrayWithObjects:self.imageView1, self.imageView2, self.label1, nil];

 NSArray *toViews = [NSArray arrayWithObjects:vc.imageView1, vc.imageView2, vc.label1, nil];

 [self pushViewController:vc fromViews:fromViews toViews:toViews duration:1.0];
