一、问题布景

1、工单反应，线上用户原生输入框修改结束点击“完结”无反响
2、经复现，仅在14Pro机型生产包上现该问题
3、查询记载，此前工单已反应过类似问题且已标记修正，猜想为非release环境验收
4、经过排查TextView相关环境，确定问题出现在键盘ToolBar，原生ToolBar由 IQKeyBoardManager库供给，H5键盘ToolBar由系统供给。

二、原生侧问题

原生侧IQKeyBoradManager供给键盘ToolBar的相关躲藏，修改事情操作。

1、移除键盘ToolBar

处理该问题最简略最快速的办法，将键盘ToolBar移除。

单个ViewController禁用键盘ToolBar:

在viewWillAppear中：
objectivec [[IQKeyboardManager sharedManager] setEnableAutoToolbar:NO];

全局禁用键盘ToolBar:

在didFinishLaunchingWithOptions中：
objectivec [[IQKeyboardManager sharedManager] setEnableAutoToolbar:NO];

2、重写键盘ToolBar”完结”按钮点击事情

在需求保留键盘ToolBar的情况，能够重写键盘ToolBar的事情来确保其正常功用。
在需求重写的ViewController中：
引进头文件：
objectivec #import <IQUIView+IQKeyboardToolbar.h>
设置Selector:
[self.view.keyboardToolbar.doneBarButton setTarget:self action:@selector(xxx)];
在xxx实现中经过setEditing或resignFirstResponder结束修改并收起键盘

三、H5侧问题

H5侧键盘ToolBar由系统供给，并没有供给相关API，所以会麻烦一些。主要经过监听系统供给的键盘告诉UIKeyboardWillShowNotification和UIKeyboardDidShowNotification,从window遍历子视图找到键盘ToolBar并做躲藏或重写事情等处理。

1、移除键盘ToolBar

增加监听：

[[NSNotificationCenter defaultCenter]  addObserver:self selector:@selector(removeKeyboardTopBar:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter]  addObserver:self selector:@selector(removeKeyboardTopBar:) name:UIKeyboardDidShowNotification object:nil];

监听事情，寻觅并躲藏ToolBar:

- (void) removeKeyboardTopBar:(NSNotification*)notify{
    UIWindow *keyboardWindow = nil;
    __block UIView* toolBarContainer = nil;
    NSArray* windows = [[UIApplication sharedApplication] windows];
    for (UIWindow *possibleWindow in windows) {
        if (![[possibleWindow class] isEqual:[UIWindow class]]) {
            keyboardWindow = possibleWindow;
            break;
        }
    }
        for (UIView *possibleFormView in [keyboardWindow subviews])
        {
            if([[[UIDevice currentDevice] systemVersion] floatValue]>8){
                if([[possibleFormView description] hasPrefix:@"<UIInputSetContainerView"])
                {
                    for(int i = 0 ; i < [possibleFormView.subviews count] ; i++)
                    {
                        UIView* hostkeyboard = [possibleFormView.subviews objectAtIndex:i];
                        if([[hostkeyboard description] hasPrefix:@"<UIInputSetHostView"])
                        {
                            for (id temp in hostkeyboard.subviews)
                            {
                                if ([[temp description] hasPrefix:@"<UIWebFormAccessory"])
                                {
                                    UIView* currentToolBar = (UIView*)temp;
                                    currentToolBar.hidden = true;
                                    toolBarContainer = hostkeyboard;
                                }
                            }
                        }
                    }
                }
            }else{
            // 兼容ios 8
                if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
                    for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {
                        if ([[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
                            [subviewWhichIsPossibleFormView removeFromSuperview];
                        }
                    }
                }
            }
        }
    if(toolBarContainer){
        if([notify.name isEqualToString:@"UIKeyboardWillShowNotification"]){
            [toolBarContainer setHidden:YES];
        }else if([notify.name isEqualToString:@"UIKeyboardDidShowNotification"]){
            [toolBarContainer setHidden:NO];
        }
        dispatch_async(dispatch_get_main_queue(), ^(){
            toolBarContainer.frame = CGRectMake(toolBarContainer.frame.origin.x,toolBarContainer.frame.origin.y+44,toolBarContainer.frame.size.width,toolBarContainer.frame.size.height);
        });
    }
    keyboardWindow = nil;
}

2、重写键盘ToolBar”完结”按钮事情:

增加监听：

[[NSNotificationCenter defaultCenter]  addObserver:self selector:@selector(dealWithKeyboardTopBar:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter]  addObserver:self selector:@selector(dealWithKeyboardTopBar:) name:UIKeyboardDidShowNotification object:nil];

监听事情，寻觅ToolBar并重写”完结”BarItem事情:

- (void) dealWithKeyboardTopBar:(NSNotification*)notify{
  UIWindow *keyboardWindow = nil;
  __block UIView* toolBarContainer = nil;
  NSArray* windows = [[UIApplication sharedApplication] windows];
  for (UIWindow *possibleWindow in windows) {
    if (![[possibleWindow class] isEqual:[UIWindow class]]) {
      keyboardWindow = possibleWindow;
      break;
    }
  }
    for (UIView *possibleFormView in [keyboardWindow subviews])
    {
      if([[[UIDevice currentDevice] systemVersion] floatValue]>8){
        if([[possibleFormView description] hasPrefix:@"<UIInputSetContainerView"])
        {
          for(int i = 0 ; i < [possibleFormView.subviews count] ; i++)
          {
            UIView* hostkeyboard = [possibleFormView.subviews objectAtIndex:i];
            if([[hostkeyboard description] hasPrefix:@"<UIInputSetHostView"])
            {
              for (id temp in hostkeyboard.subviews)
              {
                if ([[temp description] hasPrefix:@"<UIWebFormAccessory"])
                {
                  for (UIView *view in [temp subviews]) {
                    for (UIView *t in view.subviews) {
                      if ([[t description] hasPrefix:@"<UIToolbar"]) {
                        UIToolbar *barTool = (UIToolbar *)t;
                        for (UIBarButtonItem *barItem in barTool.items) {
                          if ([[barItem description] containsString:@"action=done"]) {
                        [barItem setTarget:self];                           [barItem setAction:@selector(didClickDone)];
                          }
                        }
                      }
                    }
                  }
                }
              }
            }
          }
        }
      }
    }
  if(toolBarContainer){
    if([notify.name isEqualToString:@"UIKeyboardWillShowNotification"]){
      [toolBarContainer setHidden:YES];
    }else if([notify.name isEqualToString:@"UIKeyboardDidShowNotification"]){
      [toolBarContainer setHidden:NO];
    }
    dispatch_async(dispatch_get_main_queue(), ^(){
      toolBarContainer.frame = CGRectMake(toolBarContainer.frame.origin.x,toolBarContainer.frame.origin.y+44,toolBarContainer.frame.size.width,toolBarContainer.frame.size.height);
    });
  }
  keyboardWindow = nil;
}
// 结束修改并封闭键盘
- (void)didClickDone {
  [self.view endEditing:YES];
}

至于该问题的根本原因暂未可知，欢迎各位大佬讨论
