This relates to viewing chat rooms from the App. I do not know if it occurs when viewing the chat rooms directly in Safari. I can get this to recur but I can't figure out what causes it.

Normally, the iOS Safari navigation controls aren't in the way... like this:

Good version

But sometimes, the header slips behind the Safari navigation controls:

Bad placement

This makes it difficult to read the room count and really hard to tap on the room selection drop down menu or the hamburger menu...

Can we figure out what is causing this and see about making it not happen any more?

Alternately, Safari generally hides the URL/Search bar at the top along with the forward/back arrows at the bottom unless you tap for them or scroll up on the page. If hiding were possible in this case, that would be great. If not, preventing it from happening would be appreciated.

  • Added note... I'm also familiar with the fact that the Facebook app keeps the "Done" button (actually an arrow) but makes it about half as tall when viewing content in a browser window... I'm not sure if this is what the app is trying to do or... ??? I can add an image of that if it seems helpful. – Catija May 30 '16 at 19:08

Update

I've reproduced this in iOS 9.3.2. The issue here is that SFSafariViewController is not properly calculating the body height in the CSS calculation height:calc(100%-88px). This is causing the middle section to be about 20pt too tall making the page scrollable. This can cause either the header or the text entry field to be partially hidden. I've filed radar 26867702 with Apple about the issue.


This appears to be a bug in Apple's SFSafariViewController. It's probably plotting space for the page based on a collapsed navigation bar, then expanding the status bar because the page can't scroll and not properly resizing the content. I've not yet been able to reproduce it in 9.3.2 so maybe it's fixed.

As to why the navigation bar doesn't collapse, it's because the web page itself isn't scrollable. It's a 100% height page with a fixed top and bottom bar and scrollable content in the middle. Not sure why it was designed this way but it could relate to some poor Safari behavior around focussing fixed position text fields on scrollable pages. It could be possible to design this in a different way, and that may fix the main issue of the top being hidden, but I'm inclined to leave well enough alone.

As far as how Facebook's app works, we'll never be able to replicate that because we're displaying the web in fundamentally different ways. Facebook has essentially built their own browser into the app, for a higher degree of customization and likely tracking. Our app hands off the browsing experience to Apple which presents a simplified version of Safari.

  • So if I update my phone it should be fixed, then? – Catija May 31 '16 at 17:48
  • @Catija No idea. The best I can say is maybe. – Brian Nickel May 31 '16 at 17:48
  • Fair enough. Thanks for looking into it. :) – Catija May 31 '16 at 17:49
  • So, I hate to poke you about something else but a while back I noticed that the ELL icon is different between the app and the full site. Is this something you can explain/address? – Catija May 31 '16 at 19:55
