LoadData/ SaveData not working on iOS

Posted on by akl1

I am working on an offline backup for an app with SharePoint as its main data source. It's working beautifully on Android, but not at all on iOS. I can see when reviewing the local files on my iPad Mini that it *is* saving the data, but cannot figure out why it will not load there. Any suggestions are welcome & much appreciated!

Hi @akl1,

Can you please share (in Text) all of your LoadData/SaveData/ClearData code and where you are using it.

I can, although as I say, it's working perfectly fine on Android & with the Windows desktop client, so I believe the issue is unique to iOS. OnStart property includes:
Clear(colProjectInventory); LoadData( colProjectInventory, "SavedProjectInventory", true );

Gallery with Items colProjectInventory has two button controls that can change the collection (toggling a value up & down), both SaveData as part of their OnSelect:

Button 1:

Patch(
colProjectInventory,
LookUp(
colProjectInventory,
ID = ThisItem.ID
),
{'Complete On Site?': true, 'Qty Inventoried': ThisItem.'Qty Inventoried' - 1}
),
Patch(
colProjectInventory,
LookUp(
colProjectInventory,
ID = ThisItem.ID
),
{'Complete On Site?': false, 'Qty Inventoried': ThisItem.'Qty Inventoried' - 1}
)
); SaveData(colProjectInventory, "SavedProjectInventory");

Button 2:

Patch(
colProjectInventory,
LookUp(
colProjectInventory,
ID = ThisItem.ID
),
{'Complete On Site?': true, 'Qty Inventoried': ThisItem.'Qty Inventoried' + 1}
),
Patch(
colProjectInventory,
LookUp(
colProjectInventory,
ID = ThisItem.ID
),
{'Complete On Site?': false, 'Qty Inventoried': ThisItem.'Qty Inventoried' + 1}
)
); SaveData(colProjectInventory, "SavedProjectInventory");

Hi @akl1,

Yes you are correct that the code seems valid. I have used offline functions on iPads for several years without issue (I just tested one now), so cannot offer and "lessons learnt" presently. Is the issue with a number of devices or just one ? Also if you put a label on the screen with
CountRows(colProjectInventory)

directly after start, do you see any data ?

Thanks for the tip on using CountRows() on the home page. The problem seems to be isolated to PowerApps 3.25071.7 & 3.25065.7. When I update to 3.25073.3 & add the CountRows() text, it works on all platforms.
