向没有导航控制器的视图添加导航栏

问题描述

我有一个侧边菜单，可以滑出以显示表格视图，并且从那里我有使用显示视图控制器的 segues.segue 必须直接连接到视图控制器；我不能使用导航控制器.

如何在没有导航控制器的情况下添加带有条形按钮项的导航栏?

解决方案

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它并在我的 viewWillAppear 中编写了以下代码(注意 - viewDidLoad 也可以，但不建议) -

-(无效)viewWillAppear:(BOOL)动画{UINavigationBar *myNav = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];[UINavigationBar 外观].barTintColor = [UIColor lightGrayColor];[self.view addSubview:myNav];UIBarButtonItem *cancelItem = [[UIBarButtonItem alloc] initWithTitle:@"Cancel"样式:UIBarButtonItemStyleBordered目标:自己行动:无]；UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:@"Done"样式:UIBarButtonItemStyleBordered目标:自我行动:无]；UINavigationItem *navigItem = [[UINavigationItem alloc] initWithTitle:@"导航标题"];navigItem.rightBarButtonItem = doneItem;navigItem.leftBarButtonItem = 取消项目；myNav.items = [NSArray arrayWithObjects: navigItem,nil];[UIBarButtonItem 外观].tintColor = [UIColor blueColor];}

因此，您有一个白色导航栏，其中包含蓝色栏按钮项，但没有导航控制器.同样，在您的情况下还有其他方法可以实现它.希望，这对您有所帮助.

添加图片 -

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];

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.

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

解决方案

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];
}

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.

To add images -

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];
