objective-c - 如何从虚拟键盘 IOS 中删除上一个下一个按钮

Question

我在 IOS 5 中使用了 UIWebview。我尝试设置 contenteditable="true" 以使 uiwebview 可编辑。

我的应用程序的屏幕截图类似于此链接中的图片 How do you remove the Next and Prev buttons from virtual keyboard in Sencha Touch / Phonegap application ,

我的问题是我想从键盘上删除这个上一个和下一个按钮，但我不知道该怎么做。有人可以帮助我吗？

谢谢

这是一个灰色地带，但肯定有可能。

参见此处:http://ios-blog.co.uk/iphone-development-tutorials/rich-text-editing-a-simple-start-part-1/

注册键盘显示通知:

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

然后:

- (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 *possibleFormView in [keyboardWindow subviews]) {       
        // iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
        if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
            for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {
                if ([[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
                    [subviewWhichIsPossibleFormView removeFromSuperview];
                }
            }
        }
    }
}
