WKWebview和<input type =“file”

我在iOS上遇到了WKWebView的问题。 在录制元素出现ActionSheet，其中包含三个选项： Photo Library ， iCloud ， Cancel 。

然后，当我点击照片库时 ，ActionSheet消失，WebView阻止再次打开ActionSheet。 我被卡住，通过WebView上传照片。

我在info.plist文件中添加了权限（隐私 – 照片库使用说明）。 这是我创建WebView的方法

 WKWebViewConfiguration *wkConfiguration = [[WKWebViewConfiguration alloc] init]; wkConfiguration.allowsInlineMediaPlayback = true; wkConfiguration.mediaPlaybackRequiresUserAction = false; self.webView = [[WKWebView alloc] initWithFrame:CGRectZero configuration:wkConfiguration]; self.webView.scrollView.bounces = NO; self.webView.contentScaleFactor = 2.0; self.webView.exclusiveTouch = YES; [self.webView.scrollView setDelaysContentTouches:NO]; [self.webView.scrollView setDecelerationRate:UIScrollViewDecelerationRateNormal]; self.webView.UIDelegate = self; self.webView.navigationDelegate = self; 

最糟糕的是，我无法在输入上捕捉到点击事件。 也许有人有类似的问题？ 我从Stack和Apple论坛搜索了其他主题，但都没有帮助。 我将非常感谢你的帮助。

WKWebView使用一些安全协议从OS获取文件？ 有谁知道如何处理这个？

我终于解决了。 我不得不实现UIViewController方法：

 -(void)dismissViewControllerAnimated:(BOOL)flag completion:(void (^)(void))completion { if (self.presentedViewController){ [super dismissViewControllerAnimated:flag completion:completion]; }
