Try setting mediaPlaybackRequiresUserAction to YES for the webview. I'm seeing the same issue ( UIWebView and WKWebView both) in iOS 12.2. Works fine in iOS 12.1 and earlier.

Detect and Customize UIWebView's “Unable to Read Document” error

由 最后都变了- 提交于 2020-01-02 04:12:08
问题 I'm testing a UIWebview with a number of different document types - .xlsx, .jpg, etc. - and it opens most of them just fine. From time to time, I open a local file and this message appears right in the web view: Unable to Read Document An error occurred while reading the document I'm not concerned with "why" this error occurs - it happens, for instance, when I feed the UIWebView a garbage file (intentionally). The problem is that I can't figure out how to detect "when" this happens. It doesn

UIWebView delay in loading local content

由 久未见 提交于 2020-01-02 04:02:15
问题 I'm displayed a small amount of local content in a UIWebView, roughly 3 paragraphs of text and one 100x100px image.

Here is where I'm

Why does UIWebView shrink images?

问题 I'm using a UIWebView to display images in base64 (http://www.abluestar.com/utilities/encode_base64/index.php). The UIWebView is set to "Scales Page To Fit" and Mode is "Left". The image might be 400px wide but once rendered in the UiWebView, it takes up not even half of the screen. I need to do something like style="width:800px;..." before it begins to take up most of the screen and is readable (because it isn't so small). Is this the right way? Why does the image shrink in the UIWebView and
