webview中的iOS键盘样式？

Question

我是Web开发的新手,我的项目是使用Jquery-mobile,Phonegap和指南针(scss).

默认情况下,输入字段获得焦点时显示的键盘是一个键盘,其中包含一种带字段导航功能的顶栏.我想摆脱这个导航栏,并显示iOS中最简单的键盘.我尝试将表单中的对象封装在表单中或没有表单标记,但没有成功.我没有任何线索如何实现这一点,如果可能的话,不知道:/

感谢任何建议!

要删除栏,您应该深入了解objective-c代码.

这是我使用的代码:(在包含UIWebview的控制器内添加以下代码)

首先添加一个观察者来接收键盘的通知:

-(void)viewWillAppear:(BOOL)animated{
   [[NSNotificationCenter defaultCenter] addObserver:self
                                            selector:@selector(keyboardWillShow:)
                                                name:UIKeyboardWillShowNotification
                                              object:nil];
}

- (void)keyboardWillShow:(NSNotification *)note {
    [self performSelector:@selector(removeBar) withObject:nil afterDelay:0];
}
- (void)removeBar {
  // Locate non-UIWindow.
  UIWindow *keyboardWindow = nil;
  for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
    if (![[testWindow class] isEqual:[UIWindow class]]) {
        keyboardWindow = testWindow;
        break;
    }
  }

  // Locate UIWebFormView.
  for (UIView *formView in [keyboardWindow subviews]) {
    // iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
    if ([[formView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
        for (UIView *subView in [formView subviews]) {
            if ([[subView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
                // remove the input accessory view
                [subView removeFromSuperview];
            }
            else if([[subView description] rangeOfString:@"UIImageView"].location != NSNotFound){
                // remove the line above the input accessory view (changing the frame)
                [subView setFrame:CGRectZero];
            }
        }
      }
    }
}
