Ios Webview Crash In Safari Wkwebview On Ios12 0 1 Stack Overflow There is an stange crash which only happened on ios12.0.1, our h5 file is used in the safari and our app's webview. whenever we open it on ios12.0.1, it crashed, without any log. Use instruments to check the memory usage of your app using the memory or leaks tools. fix any leaks that you find. if your app isn't consuming the memory, then try loading your html content in mobilesafari to see if (roughly) the same issue with the system getting low on memory occurs.

Ios App Crash In Webview Stack Overflow In most cases, it occurs because the view cannot be drawn due to javascript syntax and other errors on the web side. it is necessary to capture errors that occur through safari debugging. Blank web views occur on ios when a wkwebview fails or the os kills the web view's content process. ios applications normally have one main application process. Cli 8.1.1 (ios 4.5.5) cordova plugin ionic webview 4.0.0 built with phonegap build ever since ios 12 (up to 12.2) my apps users have been reporting random crashes, either white screens or the app attempting to reload. particularly on ipa. Webview.load(urlrequest(url: url(string: " google ")!)) but when i copy this to my 2 tabbed app code under the line @super.viewdidload ()@, it crashes saying "thread 1: fatal error: unexpectedly found nil while implicitly unwrapping an optional value".

Swift Ios Webkit Crash Stack Overflow Cli 8.1.1 (ios 4.5.5) cordova plugin ionic webview 4.0.0 built with phonegap build ever since ios 12 (up to 12.2) my apps users have been reporting random crashes, either white screens or the app attempting to reload. particularly on ipa.

A couple of things you could try in order to isolate the problem: 1. use the view inspector to verify that the wkwebview is actually in the view hierarchy. 2. inspect the web view with the safari. you will need the safari technology preview, but it will connect to the simulator's web view and let you inspect the contents of the webview. We are using wkwebview for our ios app. when user scrolls the webpage, goes to another page and revisits again the page ui breaks or sometimes goes blank. but when again started scrolling, ui restores. how to fix this? following is the code. let config = wkwebviewconfiguration() let usercontentcontroller = wkusercontentcontroller(). What happens sometime when the user scrolls the webview while a textarea is selected, and then they dismiss the keyboard, it leaves the section of the webview that was covered by the keyboard unusable. 我发现了一个从ios 12.0 中出现的内存泄漏，它影响了wkwebview和uiwebview。 一旦你实例化这两个leak视图中的任何一个，泄漏就会出现。 instruments确认泄漏来自javascriptcore，我猜这就是为什么它对两个网页浏览量的影响是一样的。 当我决定尝试更老的ios版本 (11.4 12.0之前的版本)时，我正试图找出我做错了什么，我注意到泄漏已经消失了。 我每次都能重现这个。 为了重现，你需要做的就是在一个类上分配一个webview的实例。 立即，您将注意到ios 12.0 12.1上的4个泄漏，如果您在ios 11.4上运行代码，这些泄漏将不再存在。 有4个单独的泄漏；3 x 96字节和1 x 128字节。.
