在iOS 9中隐藏UIWebView的快捷键盘

我正在为iOS开发PhoneGap应用程序,我需要摆脱新的iOS 9快捷键.现在我在 – (void)viewDidLoad方法中执行以下操作

if ([self.webView respondsToSelector:@selector(inputAssistantItem)]) {
    UITextInputAssistantItem *inputAssistantItem = [self.webView inputAssistantItem];
    inputAssistantItem.leadingBarButtonGroups = @[];
    inputAssistantItem.trailingBarButtonGroups = @[];
}

这隐藏了撤消/重做和复制/粘贴按钮,但快捷栏仍然显示在键盘上并且上面有导航按钮.

我怎样才能完全摆脱快捷栏.

谢谢你的帮助！

我的完整工作代码如下.希望这可以帮到某人(感谢@Clement的回复)

#import <objc/runtime.h>

- (void) hideKeyboardShortcutBar: (UIView *)view
{
    for (UIView *sub in view.subviews) {
        [self hideKeyboardShortcutBar:sub];
        if ([NSStringFromClass([sub class]) isEqualToString:@"UIWebBrowserView"]) {

            Method method = class_getInstanceMethod(sub.class,@selector(inputAccessoryView));
            IMP newImp = imp_implementationWithBlock(^(id _s) {
                if ([sub respondsToSelector:@selector(inputAssistantItem)]) {
                    UITextInputAssistantItem *inputAssistantItem = [sub inputAssistantItem];
                    inputAssistantItem.leadingBarButtonGroups = @[];
                    inputAssistantItem.trailingBarButtonGroups = @[];
                }
                return nil;
            });
            method_setImplementation(method,newImp);

        }
    }
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self hideKeyboardShortcutBar:self.webView];
}

这个技巧将隐藏撤消/重做和导航按钮.但自动预测文本仍将显示在键盘上.要隐藏快捷方式栏,请将html属性添加到输入元素中

<input autocomplete="off" autocorrect="off" autocapitalize="off" spellcheck="false" />

P.S我的应用程序现在正在审核中.仍然不知道Apple是否会批准这一点.

我的应用程序已获Apple批准

解决方法

使用方法swiziling我们可以删除键盘快捷键(仅适用于ObjC).

- (void)hideKeyboardShortcutBar
    {
        Class webBrowserClass = NSClassFromString(@"UIWebBrowserView");
        Method method = class_getInstanceMethod(webBrowserClass,@selector(inputAccessoryView));

        IMP newImp = imp_implementationWithBlock(^(id _s) {
            if ([self.webView respondsToSelector:@selector(inputAssistantItem)]) {
                UITextInputAssistantItem *inputAssistantItem = [self.webView inputAssistantItem];
                inputAssistantItem.leadingBarButtonGroups = @[];
                inputAssistantItem.trailingBarButtonGroups = @[];
            }
            return nil;
        });

        method_setImplementation(method,newImp);
    }

inputAccessoryView
: This property is typically used to attach an accessory view to the
system-supplied keyboard that is presented for UITextField and
UITextView objects.

因此,每次键盘弹出时都会触发新的实现块.

UPDATE

要从WKWebView中删除附件视图,请使用WKContentView而不是UIWebBrowserView
