iOS Question [Solved] Social Share

[Descartex]

Hi everybody!
I'm trying to enable the social share feature for my app.
I need to share an image and some text on Whatsapp, Facebook, Email, etc.
I tried the code of this post:
https://www.b4x.com/android/forum/t...elp-with-inline-objc.52849/page-6#post-336177
but it only works when I choose an online file. If I try to send a local file, it raises an error i can not debug (I have no idea about ObjectiveC, sorry)

Spoiler: Error log:

Can anyone help me to enable this feature?
Thank you so much.

Have you used the code from this post: https://www.b4x.com/android/forum/t...elp-with-inline-objc.52849/page-6#post-336177 ?

Can you upload the project?

 

[Descartex]

Yes, I used the code.
Here you have my project.
Thank you.

 

[Erel]

Your project as-is works fine here. I've tested it with SMS and Email.

Try to uninstall the existing app and install it again.

 

[Descartex]

Sorry, but I uninstalled and installed this with no changes it still crashing when I choose local file...
I've tried on Debug and Release Mode and both crash...
As i said, with online file it works perfectly.
If you look on the Error Log of my first post... it raises inside the objective C code... but I have no idea about objective C.

Thank you.

Are you testing it on a real device?

You can add log messages in the inline code to see where it crashes:

NSLog(@"1");

 

[Descartex]

Hi.
Yes, I'm testing on real device...
I was adding logs to the inline code and it crashes here:

NSLog(@"Here works");
UIActivityViewController *controller =
[[UIActivityViewController alloc]
initWithActivityItems:@[text, url, image]
applicationActivities:nil];
NSLog(@"Here crashes");

Log shows this:

One of the following values is null: text, url or image.

 

[Descartex]

For any reason, image is null...
i tried to load to an imageview and it loads...
maybe the inline code is wrong?

 

[Erel]

This is a mistake:

strImagePath = File.DirAssets & "/image.png"

It should be:

strImagePath = File.Combine(File.DirAssets, "image.png")

 

[Descartex]

I've changed it and still crashing... image stills null.

 

[Descartex]

Here is the problem...

image = [UIImage imageNamed:theimg];

I've changed it to:

image = [UIImage imageWithContentsOfFile:theimg];

and worked...
For any reason, the method ImageNamed is not working with assets folder.
Thank you!!!

BTW, the inline code should have accepted an UIImage* instead of a string. The inline code (or library code) should only implement specific features and let developers use the standard methods for all other stuff.
