Ios 导航栏右侧按钮未正确放置

我用4个项目实现了一个UITabBarController

我从AppDelegate设置初始ViewController

以下是HomeTabBarViewController ViewDidLoad代码：

在HomePagingViewController ViewDidLoad中，我设置了导航，如代码中所示

-(void)navigationSetUp{
 self.navigationController.navigationBar.translucent=NO;

    UIBarButtonItem * settingBtn=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"settings.png"] style:UIBarButtonItemStylePlain target:self action:@selector(menuHandler:)];
    UIBarButtonItem * searchBtn=[[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"settings.png"] style:UIBarButtonItemStylePlain target:self action:@selector(menuHandler:)];
    self.navigationItem.leftBarButtonItem = settingBtn;
    self.navigationItem.rightBarButtonItem = searchBtn;
    self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"ie_New_logo.png"]];
}

此后，当我更改HomePagingViewController的选项卡时，导航右侧按钮未正确放置，右侧没有边距

请帮助。

我解决了问题，代码没有问题。实际上，对于Epaper，我们使用第三方SDK，所以出现了这个问题。我删除了SDK&代码现在工作正常

您应该考虑UIBarbuttonSystemFixedSpace效果

如： UIBarButtonItem*space=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace目标：nil操作：nil]； -

为什么要使用系统导航栏？自定义导航栏很不错！例如：

我使用了相同的代码，但无法获得填充问题。请尝试设置右按钮的背景色并找到问题。嗨@vinodh，我解决了问题。你是对的，代码没有问题。实际上，对于Epaper，我们使用第三方SDK来解决这个问题。
