EnableLabels on feature layer crashes iOS 9.3

Anonymous User — Mon, 11 Jul 2016 02:15:42 GMT

Hi.

Am wondering if anyone else can replicate this crash? From what I can see, it seems to have appeared since the AppStudio upgrade to 1.2. The code below works on a desktop PC, and used to work on iPads (running up to 9.3 that I'm aware of), but new builds from AppStudio 1.2 crash.

The problem appears to the 'enableLabels' line in the featurelayer which, if set to true, crashes the app when running on iOS 9.3.2 (tested on iPad and iPhone 6).

If you can replicate, please let me know, and if you can think of a workaround - this could be a major problem if labeling if suddenly not usable on iOS devices!

import QtQuick 2.3

import ArcGIS.AppFramework 1.0

import ArcGIS.AppFramework.Runtime 1.0

App {

id: app

width: 800

height: 532

GeodatabaseFeatureServiceTable {

id: featureServiceTable

url: "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/FeatureServer/2"

}

Map {

id: map

anchors.fill: parent

focus: true

ArcGISTiledMapServiceLayer { url: "http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" }

FeatureLayer {

enableLabels: true;

featureTable: featureServiceTable

}

Hi Paul,

I tested the following code on iPad with iOS 9.3.2 and I was not able to reproduce the issue.

import QtQuick.Controls 1.2

import QtQuick 2.3

import ArcGIS.AppFramework 1.0

import ArcGIS.AppFramework.Runtime 1.0

App {

id: app

width: 800

height: 532

GeodatabaseFeatureServiceTable {

id: featureServiceTable

url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Wildfire/MapServer/0"

}

Map {

id: map

anchors.fill: parent

focus: true

ArcGISTiledMapServiceLayer { url: "http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" }

FeatureLayer {

enableLabels: true;

featureTable: featureServiceTable

}

Hi Nakul

Thanks for the reply. Could you please test again using the same feature service I did? e.g. you used a map service, whereas I used a featureservice with labels. I posted that code because it is a small snippet that is easy to test, however, the real issue for me was that the crash also occurs when the featuretable is pointing to an offline runtime geodatabase.

Let me know how you get on with the feature service for starters...

Thanks

In your featureservice I couldn't find any features. But I tested with this feature service and it worked fine. Can you please test with this one? This one is also feature Service layer.

Hi Nakul

Tested using that feature service and it crashed. Can send you app logs if you like. email me paul@gpsit.co.nz

Hi Paul,

Does the crash occur on both 32bit and 64bit iOS devices? It is possible that the crash occurs only on 64bit iOS devices. And, Nakul might be using a 32bit iPad.

Hi Shobana - I hadn't thought of that. I'm testing on an iPad Air 2 (model MGHY2X/A) and iPhone 6 which are both 64bit from what I've looked up. I'll ask around the office if we have any 32bit iOS devices I can test.

Nakul - can you clarify what iPad/device you are testing on?

Keen to hear from anyone else out there who can test too.

Cheers,

-Paul

Thanks Shobana you were right. I confirmed that I am using 32 bit Soc 4th gen iPad. I need to find one and test with a 64 bit iOS device and I'll let you know. Thanks for your patience.

Hi Paul,

AppStudio 1.2 uses Qt5.6.0 on the Cloud Make Build servers. Qt5.5.1 was used in AppStudio 1.1.

The crash that you are seeing(with Qt5.6.0) sounds similar to an iOS crash issue that was fixed in the Runtime API and included in AppStudio 1.2.

ArcGIS Runtime team is now aware of this issue. Would you please open a Tech Support incident for this so that it can tracked.

Regards

Shobana

Hi Shobana

I have sent a support request through to our NZ Esri distributor and asked them to prioritize it (we have critical app updates pending to deploy that we can't until this is resolved.)

If there's anything further I can do to help please let me know, else I'll wait to hear...

Cheers,

HI Paul,

Yes I was able to reproduce the issue in 64 bit iphone 6. I am going to log this as a defect and send you the bug id.

Thank you.

Thanks Nakul

Any idea if this is likely to be able to be fixed at the build end of things or will it require a change to the AppStudio application itself? i.e. I'm guessing that a fix at the build server end could happen anytime, but a patch/update for the application would be much slower to be made available. Obviously I'm anxious to get a resolution asap

Cheers,

Hi Paul,

Yes, this issue can be fixed at the build end as the fix is required only in ArcGIS Runtime libraries. No change is required in AppStudio application. We will do our best to resolve this issue soon. Sorry for the inconvenience.
