ios - 升级到 iOS 11 后 UiNavigationbar 按钮无响应

Question

升级到 iOS 11 和 XCode9 后，我的应用程序的 NavigationBar 按钮(左侧和右侧)没有响应。它在以前的版本中运行良好，但在 iOS 11 中运行不佳。任何人都可以帮助我或遇到同样的问题。我的应用程序是用 Objective c 语言编写的。

**//here is code for leftbarbutton**

UIImage *backSVG = [UIImage imageWithSVGNamed:@"backarrow32" targetSize:CGSizeMake(25, 25) fillColor:[UIColor whiteColor]];

UIBarButtonItem *notifyButton = [[UIBarButtonItem alloc] initWithImage:backSVG style:UIBarButtonItemStylePlain target:self action:@selector(handleBackButton)];

[notifyButton setStyle:UIBarButtonItemStylePlain];

self.navigationItem.leftBarButtonItem = notifyButton;

**//Rightbar buttons are**

 UIBarButtonItem *rightbar1 = [[UIBarButtonItem alloc] initWithImage:
 [UIImage imageWithSVGNamed:@"rightbar1" targetSize:CGSizeMake(21, 21) 
 fillColor:[UIColor whiteColor]] style:UIBarButtonItemStylePlain target:self 
 action:nil];

  [rightbar1 setAction:@selector(handlerightbar1Action)];

  UIBarButtonItem *rightbar2 = [[UIBarButtonItem alloc] initWithImage:
  [UIImage imageWithSVGNamed:@"rightbar2" targetSize:CGSizeMake(21, 21) 
  fillColor:[UIColor whiteColor]] style:UIBarButtonItemStylePlain 
  target:self action:nil];

  [rightbar2 setAction:@selector(handlerightbar2Action)];

   [rightbar1 setImageInsets:UIEdgeInsetsMake(0, -30, 0, -50)];

   self.navigationItem.rightBarButtonItems = [NSArray 
   arrayWithObjects:rightbar2, rightbar1, nil];

这个导航栏是您在界面构建器中添加的还是来自导航 Controller (推送或 Root View Controller )？

如果您可以附加来自界面生成器的 UI View Controller 的图像，它将提供问题的更多详细信息。
