您不能在 AppDelegate 中创建

打开你的 ViewController.m

- (void)viewDidLoad
 {
    self.navigationItem.title=@"Title"; //Set the title
    [self CustomButton];
    [super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}

-(void) CustomButton
{
    UIButton *but=[UIButton buttonWithType:UIButtonTypeCustom];//create a button
    but.frame=CGRectMake(290, 4, 40, 40);// set the button frame size
    [but setImage:[UIImage imageNamed:@"image.png"] forState:UIControlStateNormal];
    [but addTarget:self action:@selector(call here) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *btn = [[UIBarButtonItem alloc] initWithCustomView:but];
    self.navigationItem.rightBarButtonItem = btn;
    self.navigationController.navigationBar.barStyle = UIBarStyleDefault;

}

希望它对你有用:)

barButton 不能设置为在整个应用程序中使用。

每个都ViewController提供自己的，barButtonItems因此您必须将设置徽标和按钮的代码移动到 rootViewController 类titleViewnavigationItem

您的代码有效，我得到了徽标和按钮，但进行了一次更改

  UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
 [button setImage:[UIImage imageNamed:@"menu.png"] forState:UIControlStateNormal];
  //[button addTarget:self action:@selector(parametres:) forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(0, 0, 25, 25)];

 UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.rightBarButtonItem = rightButton;

UIImageView *navigationImage=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 120, 30)];
navigationImage.image=[UIImage imageNamed:@"menu.png"];
UIImageView *workaroundImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 120, 30)];
[workaroundImageView addSubview:navigationImage];

self.navigationItem.titleView= workaroundImageView;
self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"menu.png"]];

只需将图像类型（即不是菜单）指定为 menu.png 并通过将 UINavigationControllerDelegate 设置为您的类来将其添加到您的导航项中，如上祝您好运，请分享您的结果
