整个应用程序的 iPhone 工具栏 [英] iPhone toolbar for entire app

问题描述

我的应用程序基于 navigationController.因此，我将工具栏设置为对某些视图可见，而对于其他视图，我没有调用 setToolbarHidden:NO 或 YES.第一个问题，这在 viewWillAppear 方法中?

I have my app base on navigationController. So i set the toolbar visible for some views and for others i didnt calling setToolbarHidden:NO or YES. first question, this goes in viewWillAppear method ?

然后在我的 appDelegate 中，我在工具栏上放了一个项目但没有显示.有人可以告诉我如何在此处使用委托协议，以便每个视图都知道按下某个项目时要做什么吗?

Then in my appDelegate, I put one item on the toolbar but is not being show. can someone show me how can I use delegate protocol here so each view know what to do when a item is pressed??

我的代码:

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

    //create itemViewcontroller
    EventosViewController *itemsViewController = [[EventosViewController alloc] init];

    //create UINavigationcontroller, stack only contains itemviewcontroller
    navController=[[UINavigationController alloc] initWithRootViewController:itemsViewController];
    //navController will retain itemviewcontroller, we can release it
    [itemsViewController release];

    UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc] 
                                    initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
                                    target:self
                                    action:@selector(pressButton1:)];
    //Use this to put space in between your toolbox buttons
    UIBarButtonItem *flexItem = [[UIBarButtonItem alloc] 
                                 initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
                                 target:nil
                                 action:nil];
    //Add buttons to the array
    NSArray *items = [NSArray arrayWithObjects: systemItem1, flexItem,nil];

    //release buttons
    [systemItem1 release];
    [flexItem release];

    //add array of buttons to toolbar
    [navController.toolbar setItems:items animated:NO];

    //set navController's view in window hierarchy
    [[self window] setRootViewController:navController];
    [navController release];

    // Override point for customization after application launch.
    [self.window makeKeyAndVisible];

    return YES;
}

提前谢谢！

推荐答案

你可以像这样保留工具栏项

you can keep the toolbaritems like this

ThemeDetailViewController *themeDetail = [[ThemeDetailViewController alloc] init];
[self.navigationController pushViewController:themeDetail animated:YES];
themeDetail.toolbarItems = self.parentViewController.toolbarItems;
