iOS WKWebview 禁止长按和选择

我们可以添加些脚本到这个用户配置中，这启发了我

- (WKWebView *)webView{
    if (!_webView) {
        //创建WKWebview配置对象
        WKWebViewConfiguration*config = [[WKWebViewConfiguration alloc] init];
        config.preferences = [[WKPreferences alloc] init];
        config.preferences.minimumFontSize =10;
        config.preferences.javaScriptEnabled =YES;
        config.preferences.javaScriptCanOpenWindowsAutomatically =NO;

        NSMutableString *javascript = [NSMutableString string];
        [javascript appendString:@"document.documentElement.style.webkitTouchCallout='none';"];//禁止长按
        [javascript appendString:@"document.documentElement.style.webkitUserSelect='none';"];//禁止选择
        WKUserScript *noneSelectScript = [[WKUserScript alloc] initWithSource:javascript injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:YES];
        
        //创建webView
        WKWebView *webView = [[WKWebView alloc]initWithFrame:[UIScreen mainScreen].bounds configuration:config];
        [webView.configuration.userContentController addUserScript:noneSelectScript];
        webView.UIDelegate = self;
        webView.navigationDelegate = self;
        webView.backgroundColor = [UIColor whiteColor];
        webView.scrollView.scrollEnabled = YES;
        [webView addObserver:self forKeyPath:@"estimatedProgress" options:NSKeyValueObservingOptionNew context:nil];
        _webView = webView;

    }
    return _webView;
}

也可以直接执行JS , 这样的话要等载入完成后再执行

- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{
    [self.webView evaluateJavaScript:@"document.documentElement.style.webkitTouchCallout='none';" completionHandler:nil];
    [self.webView evaluateJavaScript:@"document.documentElement.style.webkitUserSelect='none';"completionHandler:nil];
}
