ionic - Drop down list flickers in iPAD

问题

Dropdown list in my Ionic application flickers in iPAD.

[1. On Dropdown Tap]

[2. If Tap on outside dropdown list]

[3. If Tap inside dropdown list] Once again the Image 1 will be shown.

It worked fine with iPhone 5s. But not in iPAD.

Any solution or workaround ?

EDIT:

Even if I change the orientation of iPAD, it shows the previously listed dropdown contents.

Seems to be an issue with recent update of iOS 11 and Apple's UIWebView. It works well with Apple's WKWebView.

Resolved the issue by installing cordova's WKWebView.

>> cordova plugin add cordova-plugin-wkwebview-engine --save

Then adding the following in config.xml:

<feature name="CDVWKWebViewEngine">
  <param name="ios-package" value="CDVWKWebViewEngine" />
</feature>

<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />
