WKWebview 和 <input type="file"

Question

我在 iOS 上遇到 WKWebView 的问题。点击元素 <input type="file" accept="image/*"> 后出现带有三个选项的 ActionSheet：Photo Library、iCloud、Cancel .

然后，当我点击 图片库 时，ActionSheet 消失，并且 WebView 阻止再次打开 ActionSheet。我卡住了，无法通过 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）。下面是我如何创建 WebView

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 input 上捕获点击事件。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。我会很感激你的帮助。

WKWebView 使用一些安全协议从 OS 获取文件？有人知道如何处理吗？

Answer 1

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]; 
}
