Share image with caption on whatsapp in ios 11 - ios

I have tried about share image/text on WhatsApp. so i am able to share image or text on WhatsApp successfully, but now i want to share the image with a caption on WhatsUpApplication, so I am unable to do this in swift4
so now i am searching for know how i can share image with caption on WhatsUpApplication in IOS application.
I have try with UIActivityViewController but it's not working with image and text and i read about UIDocumentInteractionController but there is no option for share both and i also implement Url Schema for WhatsApp but it's give only text sharing, not for both.
Please help me and don't make it duplicate because i didn't get any solution for it. maybe it's a issue of ios 11

Unfortunately, currently there is no way to share both image and text together on Whatsapp. It is a limitation of Whatsapp under iOS, it is nothing related to iOS11.
You can send an image or a text at a time, sharing both image and text together is not handled from the Whatsapp side.
Still, let's hope WhatsApp creates a proper iOS extension to fix this.

How do I get the height of the share sheet that shows the different apps an app can share to?

I am using a Share Extension in iOS. When a user shares with my app from another app, I would like for my ShareViewController to show above the share sheet. That means I need to know the height of the share sheet. I haven't found any answers so far. Anyone know how to do this?

How do I share a link to Whatsapp on Xamarin.iOS?

I'm working on a cross-platform PLC project on Xamarin.Forms. Specifically on iOS and Android.
In one of the views I have 3 sharing buttons, one for Whatsapp, one for Snapchat and one for general sharing. The idea is that when the user taps on one of these he sends an invitation (a deep link) to his friends trough social media.
I've implemented some android-specific code to share a link trough Whatsapp or Snapchat when tapping those buttons, and to show the normal sharing screen to pick an app on the other share button. For this I just used Intent.SetPackage method to share on the specific apps.
On iOS however, even tho there's a code to open the general sharing screen, I couldn't find any code to send the link to Whatsapp or Snapchat specifically.
My question would be, is there a way to achieve this on iOS?
This could maybe be a solution for WhatsApp, https://faq.whatsapp.com/en/general/26000030
Snapchat: Snapchat url scheme not working properly - camera opens but not profile
On the end we didn't find what we where looking for, but we noticed apps usually just have a common share button on iOS, so we left only the normal sharing code in iOS.

iOS extension- sharing bubble vs sharing button?

I have read the apple docs about app extensions- sharing
https://developer.apple.com/library/ios/documentation/General/Conceptual/ExtensibilityPG/ShareSheet.html
What they say is that when an host app has a sharing button , you can choose your app extension to share content .
But it seems that there is another sharing option that is not in the docs, and i cant figure out whats the different and how you enable this extension.
When you mark any text in ibooks ,or Safari , there is a little bubble opened with copy, past, select all, and share.
there if you hit the share button, you prompt with apps extensions, and you can share that highlighted text with the extension .
So, questions are :
the highlighted text sharing- is it enabled in every app that lets you to highlight any text ?
How you enable this extension, and is it the same as the regular sharing extension? (where you have a button with a rect and an arrow). Developing an app with sharing extension would be relevant to both cases ?
thanks.
Well , it seems that the sharing extension is working with the "bubble" sharing button , but with the regular sharing button(a rect and an arrow) you get as an input -a link to the page, much as Pocket do .
So software speaking its the same, functionality is different.
