将导航栏添加到没有导航控制器的视图中

问题描述

我有一个侧向菜单，该菜单可以滑出以显示表格视图，并且从那里可以使用显示视图控制器进行搜索。 segue必须直接连接到视图控制器。我不能使用导航控制器。

I have a side menu that slides out to display a table view and from there I have segues that use the reveal view controller. The segue has to connect directly to the view controller; I can't use a navigation controller.

如何添加不带导航按钮的带有导航栏按钮的导航栏？

How do I add a navigation bar with a bar button item without a navigation controller?

推荐答案

虽然有几种聪明的方法可以回答您的问题。我只是以编程方式解决了该问题，并在 viewWillAppear 中编写了以下代码（注意- viewDidLoad 也可以，但不建议使用）-

While there are several smart ways to answer your question. I just solved it programmatically and wrote the following code in my viewWillAppear (note - viewDidLoad is also okay, but not suggested) -

-(void) viewWillAppear:(BOOL)animated {

    UINavigationBar *myNav = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
    [UINavigationBar appearance].barTintColor = [UIColor lightGrayColor];
    [self.view addSubview:myNav];


    UIBarButtonItem *cancelItem = [[UIBarButtonItem alloc] initWithTitle:@"Cancel"
                                                                   style:UIBarButtonItemStyleBordered
                                                                  target:self
                                                                  action:nil];

    UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                                 style:UIBarButtonItemStyleBordered
                                                                target:self action:nil];


    UINavigationItem *navigItem = [[UINavigationItem alloc] initWithTitle:@"Navigation Title"];
    navigItem.rightBarButtonItem = doneItem;
    navigItem.leftBarButtonItem = cancelItem;
    myNav.items = [NSArray arrayWithObjects: navigItem,nil];

    [UIBarButtonItem appearance].tintColor = [UIColor blueColor];
}

因此，您有一个带有蓝色栏按钮项的白色导航栏，而没有Navigation控制器。同样，您还可以通过其他方法来实现它。希望对您有所帮助。

So, you have a white navigation bar with blue bar button items without a Navigation controller. Again, there are other ways to implement it in your case. Hope, this was helpful.

要添加图像-

UIImageView *myImage = [[UIImageView alloc] initWithFrame:CGRectMake(0,10,32,32)];
[myImage setImage:[UIImage imageNamed:@"image.png"]];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:myImage];
[self.view addSubview:myImage];
