Facebook Feed Dialog in Native Facebook App Browser Missing Share/Post Button - ios

I am using the Facebook Javascript SDK to bring up a feed dialog, which allows the user to post to their wall. This is working perfectly in iOS Safari but not so well when inside the Facebook app's browser. Inside of Facebook's in-app browser, the feed dialog is missing the Share button that normally appears at the top right corner of the overlay. I have attached a screenshot to illustrate. I have been grinding my gears on Google trying to find people with similar issues but have not been successful. Have you had any similar experiences? Does this look like a bug with Facebook or something that I am doing wrong. If it is the latter, can you shed some light on how I might go about fixing? Thanks!

"Add to Homescreen" for Chrome iOS

Add to Homescreen works just fine on Safari for iOS and Chrome for Android.
Saw this answer while searching before posting the question. I was wondering if anyone knows if there's been any update to this?
If it's not as simple as adding another meta tag, can someone point me in the direction of forcing this or completely removing the Url and Nav bars on Chrome?
I'd prefer to be able to save the Web App to the homescreen, of course, but am open to suggestion.
Thanks in advance!

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.

Polymer Web apps Home screen for IOS

I have a polymer web app that can be easily added to the Home Screen of an Android device.But I am not getting any way to add home screen for ios.
In google developer blog I find one post where they told it's not possible for ios.This post is now backdated.I believe there have some way to add home screen for ios/iPhone in 2017 :)

Any suggestion or help will be really appreciated.
This feature I am looking for ios
Apple does not support Progressive Web Application features yet....
They have supported an Add to Home Screen Experience since the iPhone was first released. You need the touch icons referenced in the previous answer.
You still need to manually prompt the user to add to the home screen. I have used Spinnelli's library to help, http://cubiq.org/add-to-home-screen

What embedded browser is showing ad websites?

I have banner ads (mopub with AdMob and iAds) implemented in my app. When I click "Visit Site" on some ads I get a seemingly very nicely embedded UIWebView or browser experience with site navigation and a "Done" button in the lower right hand corner. Tapping "Done" takes me back into my app.
What exactly is providing the embedded browser experience here and how do I replicate it in my app? Is this a UIWebView buried somewhere in AdMob/iAds/etc SDK? I have already embedded a UIWebview, but I would like to leverage whatever framework and code the Aads are using if possible and provide a consistent experience.
Looks like SVWebViewController is exactly what I am looking for.

Facebook like button in iPhone native application

This question seem duplicate but problem is that other question are old or not giving answer as my need.
What I have done:
I have integrated facebook for iOS 5 and iOS 6 both and it is sharing on wall properly.
Problem
My application have a UIButton "LIKE" to like my application page on facebook.
I want that if user click on this button he should be able to like that page.
I have search for hours but not able to get any proper solution.
For iOS 6 I get following link of apple iOS 6 site
iOS 6 with facebook
Here in third segment it show an image where app page is open in UIViewController with facebook like button.
and it said that we can open it without leaving our app.
I search but don't find how to open this page in UIViewController as we open dialog for share.
Ask me if you need more information.
Happy to get any kind of help or information.
As far as I know, the app shown by Apple with the Like button integrated (i.e. the App Store) is using a webview to display its content. This button is not something you get from a native code. The reason is that Facebook don't wan't to get Like actions without a user action to trigger it (I heard that from a Facebook guy at the App Day 2012 conference in Paris). And the only way to ensure that is to encapsulate and hide that in an HTML component.
What I would suggest is to instantiate a small webview displaying a page containing only the Like button of the desired page. Let us know if it work! ;-)
Mathieu is right, there is no way you can do that with a normal UIButton.
You have to use an iFrame (loaded in a UIWebView) if you want the button to like the page immediately. I did not like this approach as it takes some time for the iFrame to load.

I ended up having a UIButton that opens the Facebook page in Facebook.app or Safari.app. The user has to press the like button manually.
It's just allowed for testing purposes and iOS only.
