如何以编程方式在导航栏中设置图片？

我有一个带有导航栏的详细视图，其中带有后退按钮和视图名称。 导航栏以编程方式设置。 呈现的名称是这样设置的。

self.title = NSLocalizedString(name, @"");

该名称取决于所呈现的视图。

现在我还想在导航栏上显示一个小图标，这也取决于视图。

我怎么做？

You can 将背景图像设置为导航栏使用这个

Put in didFinishLaunchingWithOptions

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"title_bar.png"] forBarMetrics:UIBarMetricsDefault];  

或者你可以设置导航栏图像在任何视图中使用

UINavigationBar *navBar = [[self navigationController] navigationBar];
    UIImage *image = [UIImage imageNamed:@"TopBar.png"];
    [navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];

或者你可以在导航栏上设置视图 Link https://stackoverflow.com/questions/13890062/set-titleview-for-all-navigationcontroller-and-navigationitem/13890354#13890354

[[UINavigationBar appearance] addSubview:yourView]; 

or

self.navigationItem.titleView = YourView;  

And 设置标题 using h

self.navigationItem.title = @"Your Title"; 

你可以使用这个来获取navigationBarButton

-(void)getRightBarBtn
{
    UIButton *Btn =[UIButton buttonWithType:UIButtonTypeCustom];

    [Btn setFrame:CGRectMake(0.0f,0.0f,68.0f,30.0f)];
    [Btn setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"yourImage.png"]]  forState:UIControlStateNormal];
    //[Btn setTitle:@"OK" forState:UIControlStateNormal];
    //Btn.titleLabel.font = [UIFont fontWithName:@"Georgia" size:14];
    [Btn addTarget:self action:@selector(yourBtnPress:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithCustomView:Btn];
    [self.navigationItem setRightBarButtonItem:addButton];
}

并在导航栏上设置简单的imageView

UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"star.png"]];
UIBarButtonItem *backBarButton = [[UIBarButtonItem alloc] initWithCustomView:image];
self.navigationItem.rightBarButtonItem = backBarButton;
