UISplitViewController以编程方式没有nib / xib [英] UISplitViewController programmatically without nib/xib

问题描述

我通常创建没有IB内容的项目。我做的第一件事是剥离所有对xibs，outlet更新plist等的引用。没有问题，效果很好（在我的世界里）！

I usually create my projects without IB-stuff. The first thing I do is to strip off all references to xibs, outlets updated plist, etc and so forth. No problems, works great (in my world)!

现在，我刚刚安装了3.2并尝试开发我的第一个iPad应用程序。按照与以前相同的步骤，我创建了一个基于UISplitView的应用程序项目，并剥离了所有IB的东西。另外，我按照Apple的参考文档中的部分进行了操作：以编程方式创建拆分视图控制器，但是，从不显示主视图，只显示详细视图（无论方向是什么）。我真的试着仔细看看这个，但我无法理解我错过了什么。

Now, I just installed 3.2 and tried to develop my first iPad app. Following same procedure as before, I created a UISplitView-based application project and stripped off all IB-stuff. Also, I followed the section in Apple's reference docs: Creating a Split View Controller Programmatically, but nevertheless, the Master-view is never shown, only the Detail-view is (no matter what the orientation is). I really have tried to carefully look this through but I cannot understand what I have missed.

是否有一个UISplitViewController的工作示例，没有笔尖漂浮在某处？我用谷歌搜索但找不到任何东西。或者你知道我可能错过了什么吗？

Is there a working example of a UISplitViewController without the nibs floating around somewhere? I have googled but could not find any. Or do you know what I probably have missed?

推荐答案

在你的委托标题中声明你的splitviewcontroller，在你的didfinishlaunching中使用这样的东西

Declare your splitviewcontroller in your delegate header, use something like this in your didfinishlaunching

确保将UISplitViewControllerDelegate添加到detailedViewController头文件中，并且您还拥有委托方法。记得导入相关的头文件

ensure you add the UISplitViewControllerDelegate to the detailedViewController header file and that you have the delegate methods aswell. remember to import relevant header files

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{    

    splitViewController = [[UISplitViewController alloc] init];

    rootViewController *root = [[rootViewController alloc] init];
    detailedViewController *detail = [[detailedViewController alloc] init]; 

    UINavigationController *rootNav = [[UINavigationController alloc] initWithRootViewController:root];

    UINavigationController *detailNav = [[UINavigationController alloc] initWithRootViewController:detail];

    splitViewController.viewControllers = [NSArray arrayWithObjects:rootNav, detailNav, nil];
    splitViewController.delegate = detail;

    [window addSubview:splitViewController.view];

编辑 - 根据Scott的优秀建议，不要添加到windows子视图，而是

EDIT - as per Scott's excellent suggestion below, don't add to the windows subview, instead

    [self.window setRootViewController:(UIViewController*)splitViewController];  // that's the ticket
    [window makeKeyAndVisible];
    return YES;
}


//detailedView delegate methods
- (void)splitViewController:(UISplitViewController*)svc 
     willHideViewController:(UIViewController *)aViewController 
          withBarButtonItem:(UIBarButtonItem*)barButtonItem 
       forPopoverController:(UIPopoverController*)pc
{  
    [barButtonItem setTitle:@"your title"];



    self.navigationItem.leftBarButtonItem = barButtonItem;
}


- (void)splitViewController:(UISplitViewController*)svc 
     willShowViewController:(UIViewController *)aViewController 
  invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem
{
    self.navigationItem.leftBarButtonItem = nil;
}

我也更喜欢IB代码; - ）

I also prefer code to IB ;-)
