ios - 如何在 ios 7 中删除键盘的顶部栏

Question

在我的程序中，我将 UIWebView 与可编辑的 div 一起用于富文本编辑器。我需要移除键盘的顶部栏。

我使用了下面的代码 - 它只删除了下一个/上一个按钮我想删除完整的顶部栏。

- (void)removeBar {
    UIWindow *keyboardWindow = nil;
    for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
        if (![[testWindow class] isEqual:[UIWindow class]]) {
            keyboardWindow = testWindow;
            break;
        }
    }

    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];
                }
            }
        }
    }
}

我找到了适用于 iOS 8 的解决方案。您可以在这里查看:[ iOS 8 - Remove Previous/Next/Done UIKeyboard Toolbar inside a UIWebView][1]

您可以尝试改进它。尝试在您的 UIKeyboardDidShowNotification 事件处理程序中调用此函数。

希望对你有帮助...这是附件中的 View 级别:(UIWebFormAccessory) -> (UIToolbar) -> (UIImageView,UIToolbarButton,UIToolbarButton)

-(void) removeKeyboard {
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]) {

    if ([[possibleFormView description] hasPrefix : @"<UIInputSetContainerView"]) {
        for (UIView* peripheralView in possibleFormView.subviews) {

            for (UIView* peripheralView_sub in peripheralView.subviews) {


                // hides the backdrop (iOS 8)
                if ([[peripheralView_sub description] hasPrefix : @"<UIKBInputBackdropView"] && peripheralView_sub.frame.size.height == 44) {
                    [[peripheralView_sub layer] setOpacity : 0.0];

                }
                // hides the accessory bar
                if ([[peripheralView_sub description] hasPrefix : @"<UIWebFormAccessory"]) {


                    for (UIView* UIInputViewContent_sub in peripheralView_sub.subviews) {

                        CGRect frame1 = UIInputViewContent_sub.frame;
                        frame1.size.height = 0;
                        peripheralView_sub.frame = frame1;
                        UIInputViewContent_sub.frame = frame1;
                        [[peripheralView_sub layer] setOpacity : 0.0];

                    }

                    CGRect viewBounds = peripheralView_sub.frame;
                    viewBounds.size.height = 0;
                    peripheralView_sub.frame = viewBounds;

                }
            }

        }
    }
