I have an app with two dw. One is the source of data for Drag and Drop. I activate the Drag when user DoubleTap on the Source data dw. It works perfect in any android device but it does not worked in any IoS device.

Is it any settings I have to change in the IoS Device? 

I added the  leon_mobile_device.of_setassistivetouchbtnvisible (1) but users complain because it is not so easy to used. instead of just DoubleTapping. 

Any Advice will be greatly appreciated.

Appeon PowerServer 2019 Build 2151.00


I-Phone - Appeon Workspace Build 1988.00 (Downloaded from Apple Store)

Android - Build 2080.00  (Downloaded from PowerServer AWS)

Hi Clarence;

The issue is most likely because your iOS based AWS is way too out-of-date for the version of PS that you are using. I see that you mention AWS build 1988 but you are using PowerServer build 2151. Normally, the build of PS matches the AWS build as well.

I just tried my test Apps on my iOS 13.5.1 based iPad tablet. I am using PS2020 build 2328 with AWS build 2328 and the double-tap fires the DoubleClicked event and the code behind works 100%.

Note that Appeon no longer publishes updates for the AWS App on the iStore. That is why you are getting the old AWS build 1880 version. You now have two choices though to run the proper AWS build ...

1) Create your own AWS IPA from the PB IDE's PS Toolkit toolbar's "Package" icon and choose the "Custom Appeon WorkSpace" or "Standalone Mobile" option. After that, you can apply to the iStore to have that hosted for you.

2) If you upgrade to PS 2020 however, you can easily run the latest AWS for development testing by using the "TestFlight" iStore App. Once istalled, you can request TestFlight to download & install and the latest AWS App. Here are some details for that: https://demo.appeon.com/powerserver/test_appeonworkspace There is more about this also in the PS 2020 Help file.

If your PS2020 based AWS works OK and then you want to head into production - you will still need to follow alternative #1 (listed above)

FWIW: I would strongly encourage you to upgrade to PS2020 though as it contains better mobile templates for AWS code generation and packaging options for the recent iStore and PlayStore.
