iphone - 在编辑内容 UIWebView 时隐藏键盘

Question

我的项目包中的 UIWebView 显示了一个 html 文件。我想在 UIWebView 中编辑输入时隐藏 ios 键盘并显示我自己的虚拟键盘(用 Jquery 编写)。在 UIWebView 中编辑内容时是否可以隐藏键盘？我不能对元素使用 blur() 方法，因为我想编辑内容。我需要在没有 iOS 键盘的情况下执行此操作吗？

- (void)viewDidLoad
{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];
    [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:path]]];
    self.webView.delegate=self;

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

    [super viewDidLoad];

}
- (void)esconde {
     for (UIWindow *keyboardWindow in [[UIApplication sharedApplication]
windows])
         for (UIView *keyboard in [keyboardWindow subviews])
             if([[keyboard description] hasPrefix:@"<UIPeripheralHostView"]
== YES)                             [keyboard removeFromSuperview];
}
- (void)keyboardWillShow:(NSNotification *)aNotification {
[self performSelector:@selector(esconde) withObject:nil afterDelay:0];
}
