Today I made my first version of my app to run on the iPhone. When I did this I see that it paints over the area where the status bar is at the top of the screen, but that the status bar is also painted so that there is a mix of both.
I did try to set the hide status bar property of the build to true, but with the same result.
What I'd really like is that my app should retain the status bar and paint up to it but not where the status bar is.
How can i do this in Codenameone?
iOS 7 and newer expects your app to draw underneath the status bar, its a design choice by Apple and as a developer you are supposed to leave space for the status bar.
The default native theme on iOS has a StatusBar UIID style that pads the top but if you chose to remove the includeNative theme constant or remove that padding this won't work as expected.

Over the past few days, I've been struggling to figure out how to disable the Android device's bottom status (navigation) bar. (As shown in the image below)
Bottom Status Bar on Android
I've looked everywhere and tried everything to find the solution. I tried every method there was to do this, but it didn't work the way I wanted it to. The system overlays, like the bottom and top status bars, can be hidden, but they cannot be entirely disabled or concealed.
I want to know if it is possible to completely disable the status bars. I'm building an app for a marketing MV Player device and the public users can touch or interact with the application but I have to prevent them from exiting the application for security reasons.
I have tried the method given in this answer. The bottom status bar, however, will be hidden; nonetheless, it will become visible if you swipe up to the position of the status bar, or occasionally when you press the bottom of the screen.
You could use the package kiosk_mode to do what you are after. Have a look at this package.
After upgrading flutter I noticed that I have a strange looking white band under my keyboard.
I have no idea how that came to be and how to get rid of it.
My app works in fullscreen mode which might have something to do with it.
From SystemChrome.setEnabledSystemUIMode documentation:
The settings here can be overridden by the platform when System UI
becomes necessary for functionality.
For example, on Android, when the keyboard becomes visible, it will
enable the navigation bar and status bar system UI overlays. When the
keyboard is closed, Android will not restore the previous UI
visibility settings, and the UI visibility cannot be changed until 1
second after the keyboard is closed to prevent malware locking users
from navigation buttons.
You can hover over in your code and read more, but apparently it is for safety issues regarding malware lockouts.
As to why it appears white, I think it's a bug. I managed to get it working only while using manual like this, and assigning either bottom or top:
SystemChrome.setEnabledSystemUIMode(SystemUiMode.manual, overlays: [SystemUiOverlay.bottom]);
This for example while using bottom, will keep the upper status bar hidden, but shows the navigation keys. If the keyboard is needed, it appears normally, and not as a white issue. If you don't need the status bar, but you're okay with the bottom, use the SystemUiOverlay.bottom perhaps, until it's fixed.
Notice the hidden status bar on top.
Is it possible to hide (completely remove, not change the styling) the iOS Safari status bar in a homescreen web app?
When you browse a webpage in Safari in a landscape mode the status bar disappears together with the rest of the browser chrome after starting to scroll.
The web app that I'm adding to the homescreen if fitted to the size of the display so is no scrollable.
After setting:
<meta content='initial-scale=1, maximum-scale=1, user-scalable=no' name='viewport'>
<meta content='yes' name='apple-mobile-web-app-capable'>
<meta content='white-translucent' name='apple-mobile-web-app-status-bar-style'>
All the browser chrome is gone, but the status bar information is still overlaid over the top of the page regardles of the screen orientation. Is it possible to hide it?
There is no direct method for this (see: similar question) but... this link seems promising:
Everything Hybrid Web Apps Need to Know About the Status Bar in iOS7
The summary of the link is as below:
Key Comments (at link):
When viewing sites in Safari you do not have the ability to customize
the status bar in any way. Previous versions of iOS offered the
ability to view sites in full screen mode, but that was removed in
iOS7, see
http://www.mobilexweb.com/blog/safari-ios7-html5-problems-apis-review.
Key Notes (in link):
StatusBar Cordova Plugin
With iOS7 Apple introduced some native Objective C APIs to control the
status bar. Because of Cordova, we have the ability to bridge these
native APIs directly into JavaScript APIs.
Luckily for us #shazron has already done this with the StatusBar plugin.
After adding the plugin to your application, you are given a StatusBar
object with a number of methods to manipulate the status bar in
JavaScript directly.
...
You can hide the status bar using StatusBar.hide(), or even change its
background color with StatusBar.backgroundColorByName() or
StatusBar.backgroundColorByHexString().
For example, the following sets the status bar to green.
<script>
document.addEventListener('deviceready', function() {
StatusBar.overlaysWebView(false);
StatusBar.backgroundColorByName('green');
}, false);
</script>
...
Outstanding Issues
While the web has come up with workarounds for most of the iOS7 status
bar issues, there are still a few that remain unresolved.
The status bar still overlays content displayed in a cordova InAppBrowser.
There is no known workaround, but a fix is slated for cordova 3.2.
The StatusBar plugin does not work in apps that lock the device into landscape mode.
Key Critic Comment (at link):
These solutions seem to be working only for Phonegap applications, for
us who don't use this and simply wrap our apps in a webview it seems
the only easy solution is to set the webview's top property to 20
instead of zero and that takes care of the issue at hand.
I am customizing the tab bar in iOS, how to disable the blue color glow at the highlighted tab bar item ?
Will apple reject the app which disables the default blue color glow at the selected item ?
Thanks.
Pre IOS5, you can only do this with a "hack" to over-ride drawrect.
I would recommend against it, even though I have done it and had an app accepted with it (that was over a year ago though).
In IOS5 this will likely be possible with the new customisation api's.
What does
<meta name="apple-mobile-web-app-status-bar-style" content="black">
do -- can someone explain with an example?
I found this line in the official Safari Developer Library
This meta tag has no effect unless you
first specify full-screen mode as
described in “url.”
But which url?
What is the benefit of this meta tag?
First, the apple-mobile-web-app-capable hint has to be set for that to even work. This hint causes a web application to run in full-screen mode: it removes the address bar and navigation buttons you get by default in Mobile Safari. The removed areas are highlighted in red here:
So, once an app is in full-screen mode (i.e. the user has added the website to their home page), you can also control the colour of the remaining thin status bar at the top of the page with apple-mobile-web-app-status-bar-style, highlighted in red here:
Per the docs:
If content is set to default, the status bar appears normal. If set to black, the status bar has a black background. If set to black-translucent, the status bar is black and translucent. If set to default or black, the web content is displayed below the status bar. If set to black-translucent, the web content is displayed on the entire screen, partially obscured by the status bar.
A couple of caveats:
This only works on the first page you load; any navigation away to another page will make the address bar and navigation buttons reappear. So if you want this to work, you have to build a single page website (for multiple 'pages' consider an Ajax page loading approach such as that used in the jQuery Mobile framework).
This only works when you arrive at the web page via an application shortcut icon; if you navigate to the website directly from within Mobile Safari it has no effect.
It changes the top bar w/ the banner and carrier on it and makes it a translucent black.
