I have an app on the store which is built using Ratchet framework. It used to work fine, until iOS 8 was released. Now when I test it on iOS 8, title bars for modals won't appear. All the controls like Close, Back buttons on the bar work when I click, but the bar and the controls on it are not visible. This happens only on iOS 8, works fine on iOS 7 and older versions.
To reproduce this bug, please open this sample app http://goratchet.com/examples/app-android-notes in Safari on an iOS 8 device or simulator, and then click on New note button to open a modal.
I've noticed while debugging it in Safari's web inspector that if I move the bar <header>...</header> element of the modal to somewhere else and then bring it back to its original position, it appears. Or sometimes, changing its display property from block to none and then back to block works. Or sometimes if I scroll the page.
Any solution will be highly appreciated
Seems there is an issue with position: fixed in Safari as discussed in this SO question: Mobile safari position:fixed z-index glitch when scrolling
You can fix it by adding this rule to your CSS
header.bar.bar-nav {
-webkit-transform: translateZ(0);
}
You can track the issue on Ratchet's Github repository here - https://github.com/twbs/ratchet/issues/679
You should try position:sticky;. It's made to deal with position on Safari. fixed has been an issue with mobile devices for years. I thought it was fixed but iOs8 has weird behavior too...

I have a fully-responsive website, but after the release of iPhone 11, I have tried visiting the site, but what I get is a blank navigation menu, on Chrome and Safari. On all other devices, the menu is displaying properly. On iPhone 11, the navigation items/links are completely blank. What might cause this problem?
The site is already tested on all other Android and Apple devices, the menu works properly.

Your problem is with mobmenu-content style and element positioning.
It could be fixed with removing either position: fixed attribute or overflow: auto. Then the menu becomes visible on iOS 13 browsers.
I've looked into stackoverflow and it seems that position:fixed in an iframe for iOS mobile devices has been an issue in the past but have yet to have an answer.
Here's an example I created via jsbin: http://jsbin.com/pekeca/1/
In that example, there is a parent HTML page that uses iframe which contains another HTML page (child). Here are the things to note:
When the parent HTML is viewed on any device, the navigation bar in the child HTML stays fixed. This is the intended behavior.
However, when the parent HTML is viewed on an iPhone regardless of the browser, the navigation bar in the child HTML loses its fixed position. This is a bug that only happens in iPhones.
When the child HTML page is viewed directly (i.e., not inside an iframe) in an iPhone, the navigation bar stays in a fixed position and works fine.
Has anyone figured out a workaround for position:fixed in iPhones or iOS devices?
In Chrome and Safari on iOS it seems the issue here is not the fixed position, but with the height of the iframe. From another SO answer: "Starting in version 4.2.1 of Safari iOS, and still going as of 4.3.3, the entire content of an iFrame is forcibly shown."

We are writing a Cordova/jQuery Mobile app, and coming across an issue with iOS (both 6 and 7). The problem is that CSS is sometimes in iOS is not being applied, even though it should be. The problem is both in the emulator and device itself.
For instance:
A background-color: red is displayed as white.
An element with overflow:scroll (both with and without -webkit-overflow-scrolling: touch) cannot be scrolled.
It's not an inheritance issue - the same CSS works fine in desktop FF, Chrome, Safari, IE and in Android. It also works fine using Safari remote inspection - the style won't be displayed initially, but simply un-checking and then re-checking the property in the Safari developer tools makes it work normally !
I have not be able to isolate what causes this problem, but when it happens it happens consistently. Is there a fix for this problem ?
It should work fine for iOS6. You can try using hexadecimal code for background color and add
-webkit-overflow-scrolling: touch; for smooth scrolling.
For iOS7 the bellow link may help you.

I am building a small app using PhoneGap HTML/CSS. Now my problem is that position:fixed (used on a top bar) works on iOS 5 but not on iOS 4. Someone knows a fix for this?
Position:fixed doesn't work on iOS before version 5 and some other mobile browsers. There are a lot of solutions out there for this, but one that I can personally recommend is GloveBox written by Nitobi's own Jesse MacFadyen. It lets you define areas that are scrollable, and I believe in your case that would be the main content, while the top bar isn't scrollable.
Another advantage of this approach is that the user won't be able to "scroll out" of your app's view as if it were a normal website on Mobile Safari.
I created an iOS app last year using html, css, js, jqtouch and phonegap. The app has worked well until recently. It appears that since the iOS 5 update, there is a problem with the navigation.
If you scroll down the apps "pages" and try to select any options below the original screen horizon, the navigation doesn't work. Scroll back all the way to the top of the page and the links above the screen horizon all work. If you scroll back up the page, but not all the way to the original starting position, even the links that are above the original screen horizon won't work.
I worked with Phonegap support and they suggested the problem was with jqtouch. I updated the jqtouch files in the project, and now when I try to run the app (from Xcode) in the iPhone simulator or on a test device, the navigation doesn't work at all. Before, the "links/buttons" would change color as they were supposed to but no work. Now, the "links/buttons" won't change color or navigate to the next div or page.
Could someone tell me what I may have missed in updating the jqtouch/jquery files that could cause this?
We had the same issue and e solve it updaing to the latest jquery and jqtouch version.
Hopefully this will help you.
