Are you using Splash screen properly?

Are you using Splash screen properly?

@adeelcap15 As far as I'm concerned, Cordova6.1.0 has cancelled CDVSplashScreen, In file "CDVViewController.m", it launched The LaunchView by itself. I tried to block the code: [self createLaunchView]; the display time of blank screen reduced to 1 second

[adeelcap15]

IMHO you should use the newer CDVLaunchScreen. It's working fine on Cordova IOS 6.1.1 on iOS 14

@lynntangyuan Did you manage to solve the issue? We are having the same issue, but I cant figure out what is triggering the white screen.

@adeelcap15 Does the CDVLaunchScreen support the legacy splash screen? If possible we would rather not use the story board in order to keep the same resolution when running the app on the iPad Pro (iPad Pro scale issue).

Support for legacy launch screens was removed in 6.0.0 via https://github.com/apache/cordova-ios/pull/790

I think the main reason for this is Apple will reject any apps still using legacy splash screens, as of April 2020.

After that, when app tried to load CDVViewController based on WKWebview, the blank screen appeared. @asa47 are U under the same circumstances as I described above? Sorry to info that I haven't solve this issue yet.

@lynntangyuan Yes I sorted the issue on our side, however I am still using the legacy launch screen.

Regarding the white screen, it looks like it is caused by the JS code not being loaded quickly enough in the WebView after displaying the splash/launch screen. In order to fix the issue, I manually hide the splash screen in the javascript side with navigator.splashscreen.hide(). Just remember to add the following in your config.xml: <preference name="AutoHideSplashScreen" value="false" />
