ios - WKWebview和<input type =“file”

我在iOS上的 WKWebView 遇到问题。点按元素<input type="file" accept="image/*">后，将显示带有三个选项的ActionSheet:图片库，iCloud，取消。
然后，当我点击照片库时，ActionSheet消失了，并且WebView阻止再次打开ActionSheet。我很困惑，无法通过WebView上传照片。
我已经在info.plist文件中添加了权限(隐私-图片库使用说明)。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，我无法在输入中捕获轻击事件。也许有人有类似的问题？我在Stack和Apple论坛中搜索了其他主题，但都没有帮助。感谢您的帮助。

WKWebView使用某种安全协议从OS提取文件吗？有人知道如何处理吗？

最佳答案

我终于解决了。我必须实现UIViewController方法:

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

关于ios - WKWebview和<input type =“file”，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/44848761/
