Weird new IOS Issue-

[ToddFrankson 1]

So, I have been working on a multi platform project, that has worked fine on Windows Android and IOS.

IOS just updated to 17.5.1

The code works fine Prior to the update, but not after.

 

I use TNetHttpClient to do a get of a web page.  Prior to the Get, a Head returns just fine, to ensure internet access.

I made a simple sample of the code.  

tap a button to initiate the Get and load the same page in a Twebbrowser.

 

Can anyone text the attached code and tell me why the Get doesn't "get"? And why it works fine Prior to 17.5.1, and on all other platforms??

 

When the button is clicked, the Webbrowser browses the page, and the memo never gets filled.

Have you set the NSAppTransportSecurity and other Flags in the info.plist, according to your needs?
Here is a sample, for various settings:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <!-- Example for >= iOS 9  -->
    <key>NSExceptionDomains</key>
    <dict>
        <key>example.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>

I never had to set anything before.  Especially in the sandbox.

I'm unable to reach that URL at all.

Interesting.  It's a local county government page.

I can from Windows 10. I don't have an iOS device to test.

That site seems geolocked to the US, I only get an error 403.

Nope.

This link works
https://www.cravencountync.gov/263/GIS-Mapping

but clicking from there into
https://gis.cravencountync.gov/
doesn't work on Windows 11.

Ok, I'm not living in USA, so maybe some kind of IP-blocking?

 

Edit:

Yes, after VPN I can reach this from Windows.

So, I have figured out my problem.  Please alter the code with a web page you can hit.

 

It seems that IOS No longer likes Getdocumentspath....A Stringlist failed to write to it, using Assign and reset failed to open or read the file....

 

All in development mode.

 

Can anyone check this?

Your example code does not have any calls to Assign or Reset. Having said that, why are you using long deprecated file access methods? TStringList has LoadFromFile and SaveToFile methods.

 

It might help to show an example that focuses just on GetDocumentsPath and the file access parts, if that's what is failing

The failure Occurs in the code i posted with the Stringlist.SavetoFile.  No ERROR PRESENTED. I had to wrap almost everything with message Dialogs to find the failure.  

 

I tried Assign /reset just on a whim .

 

I have attached a new unit.pas.  On line 92 & 93 put a URL you know you can get too.

Using a URL I can reach, the code works fine for me

Yes, to both. Have you tried another URL?

Yes, several files. Everytime I get a cannot write..... user doesn't have sufficient rights error, only displaying when I specifically show the error in a message. When I remove the try except, the file doesn't exist to open. 

 

I just spent the day on the main project, using message dialogs to find this out. I am now using temppath.
