Debugging sporadic app crashes with dylib in iOS13/iPadOS 13

由 空扰寡人 提交于 2019-12-23 09:27:01
问题 After updating to iOS 13.x / iPadOS 13.x we see sporadic crashes with our recent Testflight builds. We've not seen reports from users using our pre-13 released version yet, but it seems not many have updated to 13 yet, so we really don't know. The app is a cordova-app with cordova-ios 5.0.2 using WkWebView. Data protection entitlement is set to full. I have a hard time making sense of the crash, and it seems to be somewhere deep in the iOS-stack? The crash is sporadic and seems only to happen

Draw on it is fine, but erase is not possible. 回答3: First, put your UIImageView

问题 Silent notification is not working in iPadOS. But, in 12.4 OS it is working fine. { "aps": { "content-available" : "1" }, "BuildingId":13, "NotificationTypeId":214, "CustomerName":"Test", "Amount":"6778", "CustomerID":32752, "Environment":"TEST", "Title":"" } 回答1: Adding "apns-push-type" header field solved the issue.

问题 In iOS 13 apple changed the user-agent that iPad uses.

iPadOS: Network connected via NEHotspotConfiguration disconnects after a while

问题 My app uses NEHotspotConfigurationManager to connect itself to a certain device using a Wi-Fi. The device acts as an WPA2 access point. In older iOS versions (iOS 12 and lower) everything worked fine, but in iPadOS/iOS 13 the device is being disconnected after a while every single time. How to keep a connection on without storing NEHotspotConfiguration permanently? I suspect that it has something to do with a new feature - Multiple Windows (which is not supported by my app). The reason is
