iOS Question How to share a pdf file to social media functionality?

[PierPaduan]

Hi All,

I tried the code of this post:
https://www.b4x.com/android/forum/t...elp-with-inline-objc.52849/page-6#post-336177

It works fine with local images, but the app crashes if I try to share a local pdf file.

'strImagePath = File.DirAssets & "/image.png"
strImagePath = File.DirAssets & "/5.pdf"

"5.pdf" has been loaded in Files subdirectory of the project and has been added in Files Manager tab.

The error is:

Application_Start
Application_Active
Error occurred on line: 114 (modShare)

Thanks Erel, but may be I don't apply correctly what you are suggesting.

I've changed:

'strImagePath = File.DirAssets & "/image.png"
'strImagePath = File.DirAssets & "/5.pdf"
strImagePath = File.Combine(File.DirAssets, "5.pdf")

and changed:

//image = [UIImage imageNamed:theimg];
image = [UIImage imageWithContentsOfFile:theimg];

But the error is still the same.

What ca I do?

You are trying to share a PDF file as an image... you have to share it as a binary i think...

Thanks a Lot Erel.

Do you have an example where I can start from?
