如何编写objective-c函数

我使用以下代码切换视图

- (void)loading2menu{

[UIView beginAnimations:@"Loading2Menu" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

if (self.menuViewController.view.superview == nil)
{
    if (self.menuViewController == nil)
    {
        MenuViewController *menuController = 
        [[MenuViewController alloc] initWithNibName:@"MenuView" 
                                             bundle:nil];
        self.menuViewController = menuController;
        [menuController release];
    }

    [UIView setAnimationTransition:
     UIViewAnimationTransitionCurlUp
                           forView:self.view cache:YES];

    [loadingViewController viewWillAppear:YES];
    [menuViewController viewWillDisappear:YES];
    [loadingViewController.view removeFromSuperview];
    [self.view insertSubview:menuViewController.view atIndex:0];
    [menuViewController viewDidDisappear:YES];
    [loadingViewController viewDidAppear:YES];
}
else
{
    if (self.loadingViewController == nil)
    {
        LoadingViewController *loadingController = 
        [[LoadingViewController alloc] initWithNibName:@"LoadingView" 
                                                bundle:nil];
        self.loadingViewController = loadingController;
        [loadingController release];
    }

    [UIView setAnimationTransition:
     UIViewAnimationTransitionCurlDown
                           forView:self.view cache:YES];

    [menuViewController viewWillAppear:YES];
    [loadingViewController viewWillDisappear:YES];
    [menuViewController.view removeFromSuperview];
    [self.view insertSubview:loadingViewController.view atIndex:0];
    [loadingViewController viewDidDisappear:YES];
    [menuViewController viewDidAppear:YES];        
}

[UIView commitAnimations];

}

我认为代码太多了，而且如果我有更多的视图要切换，我必须编写更多这样的代码，这是浪费时间的，而且这不是最好的方法，所以我编写了一个函数来做同样的事情

- (void)switchtheviews:(UIViewController*)coming over:(UIViewController*)going {    
[UIView beginAnimations:@"frame" context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];   
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:viewController.view cache:YES];
[coming viewWillAppear:YES];
[going viewWillDisappear:YES];
[going.view removeFromSuperview];
[viewController.view insertSubview:coming.view atIndex:0];
[going viewDidDisappear:YES];
[coming viewDidAppear:YES];
[UIView commitAnimations];

  }

那么，我如何调用这个函数呢？如果我用旧的，我可以用

[[MyAppsAppDelegate App].switchViewController loading2menu];

---

但是这个新函数，调用这个新函数我应该写些什么呢？谢谢你，我认为你不需要用动画来做你正在做的事情。应该是这样的：

[objectName removeFromSuperview];
[superViewName addSubview:otherView];

要调用函数，它应该是：

[object switchTheViews:viewController over:otherViewController];

---

您可以这样编写一个C函数：

void switchtheviews(UIViewController *coming, UIViewController *going)
{
...
/* there is no self here */
...
}

并在代码中的任何位置使用它：

切换视图（v1、v2）

我认为这不是你想要的。您可以编写一个私有方法来做同样的事情，并将所有内容封装在类中。在您的
.m
文件上尝试类似的内容（这是私人内容，无需将其放在
.h
上）：

正如您在其他答案中所看到的，有更简单的方法来切换视图。我只是回答问题的语法部分。
你能澄清一下你想做什么吗？您只是想用另一个视图替换一个视图吗？是的，我只是想通过编写更少的代码来用另一个视图替换一个视图。我还想知道如何在代码中调用函数“switchtheviews”，谢谢
// MegaCoolViewController.m

@interface MegaCoolViewController ()

- (void)_switchtheviews:(UIViewController*)coming over:(UIViewController*)going;

@end


@implementation MegaCoolViewController

#pragma mark - Private

- (void)_switchtheviews:(UIViewController*)coming over:(UIViewController*)going
{
/* do your thing, use self freely */
}
