I have been experiencing the same issue, and have tried in the past 2 weeks numerous solutions found online for this with no success, any help appreciated :)
I am writing a simple app using Cordova for IOS and Android and building it using Phonegap build. The problem is that I cannot get the "navigator.geolocation.getCurrentPosition" (or navigator.geolocation.watchPosition) calls to return anything except a timeout error on iOS. (works perfectly on Android)
Additionally, the location services dialog never appears (requesting user permission to allow GPS for the app)
To add to this strange behavior, it seems that i have to touch the screen after the app is loaded to initiate the geolocation call, on most cases the app just sits there and does nothing until the screen is touched.
Testing this on iPhone 5 with iOS 9
Things I tried:
Changing timeout settings (up to 30 seconds)
Setting enableHighAccuracy true/false
Running code with or without the geolocation plugin
Manually adding the NSLocationWhenInUseUsageDescription/NSLocationAlwaysUsageDescription settings (or both) to the plist file
Installing different plugin versions for the geolocation plugin
Changing Content Security Policy meta tag
Trying to add or remove the <plugin> declaration from root config.xml
Current plugins installed ($cordova plugin list):
cordova-plugin-dialogs 1.2.0 "Notification"
cordova-plugin-geolocation 1.0.1 "Geolocation"
cordova-plugin-whitelist 1.2.0 "Whitelist"
cordova.plugins.diagnostic 2.3.5 "Diagnostic"

Oh. that's it. I should be more dogmatic on this. This should take care of the problem.
It is not advisable to use Phonegap CLI to make your Phonegap Build build project. Phonegap build requires that index.html and config.xml both sit in the root directory. All the extra files that you are required to use with Phonegap CLI, never are created or needed with Phonegap Build.
So, I'm going to give you one of my working demos. Notice that all the files are in one (1) directory.
tutorial/blog entry - An HTML Boilerplate for Phonegap Build
source code Phonegap--Generic-Boilerplate
Notice how the compiler version is set to:
<preference name="phonegap-version" value="cli-5.2.0" />
Notice, if you change cli-5.2.0 to 3.7.0, nothing appears to change.
Basically for Phonegap Build, you need index.html and config.xml - that's it. Then for security reasons (as of Cordova Tools 5.0.0), it is advisable to create a css file and a javascript file. However, I'll show you how to get around this.
Here is my complete list of Demo Apps.
Phonegap Demo Apps
YOUR FIX
This is my working code, test with 3.5.0 and cli-5.1.1 and cli5.2.0
source code Phonegap-GPS-Test
On Your fix, notice how the version is set to: <preference name="phonegap-version" value="3.5.0" />
Okay, I trust all of this will work for you. As such, your documentation is here:
https://build.phonegap.com/docs
There are some special rules for adding plugins, but I'll give you those when your program is running.
How to add Plugins with Phonegap Build
FOR THE MOST IMMEDIATE FUTURE, get your *core* plugins from this list:
http://cordova.apache.org/docs/en/5.4.0/cordova/plugins/pluginapis.html
Get your 3rd-party plugin from this source:
http://cordova.apache.org/plugins/
When using Phonegap Build, sometimes the pluins get fixed (or updated) and this breaks Phonegap Build. This is because the "fixes" require the latest version of the compiler, and Phonegap Build is always at least one version behind.
There are two ways to deal with 3; see 4 and 5.
I have created this Worksheet. You may want to make a copy or just use it as a reference. I use this worksheet to create my demos, I so know the list is good. I am working on cli-5.2.0 right now. (Should finish by Monday or so.) However, I do not test ALL 3rd-party plugins; there are 800+ plugins.
If you fail to set the version number on a plugin, you will get the latest version. If your build fails, then set the version. If the build still fails, try the previous two or three version to find one that works. NOTE, these older plugins may have bugs that prevent you from using them. So, try an even earlier version.
Lastly, if you think you have hit a bug, then here is a page with links to the Bug respository for each plugin. Last Update is on the top left. Best of Luck.

I'm writing an app with Cordova 11.0.0, cordova-ios 6.2.0, and Xcode 13.3 that sets the background image to the user's choice. Everything works fine on Android and on the iOS simulator. However, when running on a physical iPhone SE (2022) with iOS 15.4, the background image is not displayed, though it seems to set style.backgroundImage correctly on the element, and I'm able to read the image file correctly using a standard FileReader object. It appears that any local images using a file:// URL are not displayed. I'm loading them from under cordova.file.dataDirectory, so I can't just convert to a relative http:// URL. I believe my Content-Security-Policy is permissive enough (?) (see index.html below).
I made a small demo of this; the only plugin it uses is cordova-plugin-file 6.0.2. My config.xml contains:
<content src="index.html" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />
<platform name="ios">
<preference name="allowFileAccessFromFileURLs" value="true" />
<preference name="allowUniversalAccessFromFileURLs" value="true" />
</platform>
My index.html is:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Security-Policy"
content="default-src * file: filesystem: ; img-src * file: filesystem: ; style-src * file: filesystem: 'unsafe-eval' ;">
<meta name="viewport" content="initial-scale=1, width=device-width, viewport-fit=cover">
<link rel="stylesheet" href="css/index.css">
<title>Hello World</title>
<script src="cordova.js"></script>
<script src="js/index.js"></script>
</head>
<body>
<h1>Background image should show up</h1>
</body>
</html>
My index.js is:
// Wait for the deviceready event before using any of Cordova's device APIs.
document.addEventListener('deviceready', onDeviceReady, false);
async function onDeviceReady() {
try{
// this block just copies file from under cordova.file.applicationDirectory
// to under cordova.file.dataDirectory, for this demo
// FileEntry.copyTo() throws error on ios if file already exists, so use try/catch
try {
let entry= await new Promise((resolve, reject) =>
resolveLocalFileSystemURL(cordova.file.applicationDirectory + 'www/img/home_bg.jpg',
resolve, reject) ) ;
let dest_dir= await new Promise((resolve, reject) =>
resolveLocalFileSystemURL(cordova.file.dataDirectory, resolve, reject) ) ;
await new Promise((resolve, reject) =>
entry.copyTo(dest_dir, undefined, resolve, reject) ) ;
} catch(e) {}
// set full background property
let full_url= cordova.file.dataDirectory + 'home_bg.jpg' ;
document.body.style.background= 'url(' + full_url + ') center/cover' ;
// this shows the correct 'url("file:///Users/.../Library/NoCloud/home_bg.jpg")'
alert('computed backgroundImage=[' + getComputedStyle(document.body).backgroundImage + ']') ;
} catch(e) {
alert('in odr(): '+e) ;
}
}
My index.css is simply:
body {
height:100vh;
width:100vw;
}
h1 {
font-size:24pt;
margin:3rem;
text-align:center;
}
And finally, I have a background image in img/home_bg.jpg that is copied to be under cordova.file.dataDirectory.
I've read many questions here about file:// URLs, but none of the solutions have worked and are appropriate (e.g. using data: URLs for the images is impractical and unscalable). I know that the app paths change for every install on an iPhone, but the code above should still work.
How can I get images to display on a physical iPhone using file:// URLs? Am I missing some setting in Xcode or elsewhere?
Thanks for any help!
Thanks to this answer by #jcbdrn, I managed to work around this by using blob: URLs for all displayed images:
let blob= new Blob([await read_file_binary(file_entry)]) ;
img.src= URL.createObjectURL(blob) ;
... where read_file_binary() reads a file as an arrayBuffer. Note that the Content Security Policy must include blob: in the img-src directive.
This isn't as efficient as just using file: URLs, but it's much better than using data: URLs. It does seem like a bug in either cordova-ios (?) or in WKWebView (?), but I'm set for now.
I've been using the cordova-plugin-inappbrowser plugin for a long time now and when I updated the software to 10.2.1 on my apple test devices the plugin no longs works properly. When I try to open the inappbrowser link nothings happens unless I click the home button and return to the app. This happens for the simulators as well as on real devices like ipad, iphone 5s, iphone 6 and iphone 7. it works fine on android devices just not the latest iOS.
Here's a list of everything i tried:
updated inappbrowser to latest version - 1.7.1
removed and reinstalled the plugin and ios platform
tried making a blank app with the inappbrowser plugin
tried changing the index.html meta tag to include gap:
<meta http-equiv="Content-Security-Policy" content="default-src * 'self' gap: ; script-src 'self' 'unsafe-inline' 'unsafe-eval' *; style-src 'self' 'unsafe-inline' *; child-src 'self' 'unsafe-inline' *;">
I can't seem to find anything else to try as most posts I do find that have a similar issue haven't been answered.
Below is the relevant code to how the inappbrowser plugin was installed and is being used:
config.xml Structure
<widget>
<content src="index.html"/>
<access origin="*"/>
<allow-navigation href="*"/>
<preference/>
...
<feature name="StatusBar">
...
</feature>
<platform name="ios">
... icons and splash ...
</platform>
<plugin name="cordova-plugin-inappbrowser" spec="~1.7.1"/>
</widget>
Using plugin in Controller
$scope.showLink = function(url){
var options = {
location: 'yes'
}
$cordovaInAppBrowser.open(url, '_blank', options)
.then(function(event){
// success
console.log('inappbrowser', event);
})
.catch (function(event) {
// error
console.log('inappbrowser error', event);
});
};
$scope.openUrl = function(url) {
window.open(url, '_blank', 'location=no');
};
I'm using ionic v1.7.14 , cordova: 6.2.0 and xcode 8
As suggested by CodeGems, in the comments, adding gap://ready to your Content-Security-Policy should fix the issue.
In a Cordova app that I am working on there is an iframe. The problem is that when testing the app (both simulator and on device) the iframe is blank. On Android the iframe works perfectly however.
The iframe is loaded dynamicly in an Angular directive.
Within the directive link function the following code is used to load and append the iframe to the directive's element:
var iframe = angular.element('<iframe class="widget" width="' + widgetWidth + '" height="' + widgetHeight + '"></iframe>');
iframe.attr('src', url);
element.append(iframe);
I have also tried using something in the following lines:
var iframe = document.createElement('iframe');
iframe.src = url;
This results in somthing like the following (using Safari web inspector):
<iframe class="widget" width="384" height="505" src="http://hostname/correct/uri"></iframe>
In my index.html file I have the following set:
<meta http-equiv="Content-Security-Policy" content="script-src * 'unsafe-eval'; connect-src * 'unsafe-eval'; object-src 'self'; style-src * 'unsafe-inline';">
I also have the following lines in my cordova config.xml:
<access origin="*" subdomains="true" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />
There is also no errors or warnings in Safari Web Inspector.
So my question is, is there some trickery to get iFrames to work in Cordova iOS apps that I am missing. Or what is wrong with my current config/code?
I am using angularjs 1.5.3 and have jquery 2.2.1 (loaded before angularjs) in case that helps.
The problem was the allow-navigation tag. So to solve it I only had to put the <allow-navigation href="*" /> tag into the project's config.xml file.
I came to the solution through the output box in xcode while the simulator was running. There was a message containing the url of the iframe in question and something about "internal navigation rejected".
Have you tried setting child-src and/or frame-ancestors in the Content-Security-Policy meta tag? These may need setting to * also or something more restrictive like just the iframe source URL(s) you are using.
There's information about this at content-security-policy.com
Example based on your content security policy:
<meta http-equiv="Content-Security-Policy" content="script-src * 'unsafe-eval'; child-src *; connect-src * 'unsafe-eval'; object-src 'self'; style-src * 'unsafe-inline';">
The deviceReady event is not fired when starting the app.
Dragging the notifications list down from the top of the screen and releasing then causes the deviceReady to fire.
Similarly, trying to display a page in the inAppBrowser doesn't display until the notifications are dragged down and released.
Key elements in the config.xml are:-
<gap:plugin name="cordova-plugin-whitelist" version="1.0.0" source="npm" />
<gap:plugin name="cordova-plugin-inappbrowser" source="npm" version="1.0.1" />
<gap:plugin name="cordova-plugin-device" source="npm" version="1.0.1" />
<preference name="permissions" value="none"/>
<preference name="fullscreen" value="true" />
<preference name="exit-on-suspend" value="true" />
Html:-
<!DOCTYPE html >
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Home</title>
<meta http-equiv="Content-Security-Policy" .... />
</head>

<div id="idSplashMessage">Starting up ...</div>
</div>
<div id="idSplashBody"></div>
<div id="idSplashFooter"><a id="idTestLink" href="javascript:null" target="_blank">Click here for google</a></div>
</div>
<!-- ************************************************************************** -->
<script src="js/jquery-2.0.3.min.js" type="text/JavaScript" ></script>
<script type="text/JavaScript">
$(document).ready(function () {
function onReady() {
$("#idSplashMessage").text("deviceReady");
alert("deviceReady");
}
document.addEventListener("deviceReady", onReady, false);
$("#idTestLink").click(function () {
var win = window.open(encodeURI("http://www.google.co.uk"), '_blank', 'location=yes');
return false;
});
});
</script>
<script src="cordova.js" type="text/JavaScript"></script>
</body>
</html>
The source of the problems was the inclusion of a content security policy in the html.
Although I believe the CSP was entirely valid, and did not cause any issues with Android, I removed it which allowed the IOS version to work.
The CSP was added in the first place due to an error log from the whitelist plug in suggesting it was required.
#Grebe,
this is a common misunderstanding with developers new to Cordova/Phonegap.
From: Top Mistakes by Developers new to Cordova/Phonegap
4. In the code, did not listen for the 'deviceready' event.
(...) the section of documentation we need.
This is a very important event that every Cordova application should use.
Cordova consists of two code bases: native and JavaScript. While the native code is loading, a custom loading image is displayed. However, JavaScript is only loaded once the DOM loads. This means your web application could, potentially, call a Cordova JavaScript function before it is loaded.
The Cordova deviceready event fires once Cordova has fully loaded. After the device has fired, you can safely make calls to Cordova function.
This means you must do this before you call any other libraries.
This also means you need to load cordova.js before jquery.
EXAMPLE
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
// _OR_ JUST
document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is loaded and it is now safe to make calls Cordova methods
//
function onDeviceReady() {
document.addEventListener("pause", onPause, false);
$(document).ready(function () {
// Call the usual stuff.
}
}
Okay I've been working on this issue for a while now and can't figure this thing out. Simple PhoneGap test app, trying to show an alert.
Using Cordova 2.9.0 for iOS. I've added some simple test code and tested it in chrome to see where it breaks, because it isn't working in the emulator
When I test in the Chrome (of course same result in emulator, but no error message is showing)
It executes the onDeviceReady as it should
It sets tb2 textbox value to 'before alert'
Then it breaks with the error: Uncaught TypeError: Cannot call method 'alert' of undefined, on this line: navigator.notification.alert(...
It should be referencing the cordova.js properly, here is the structure of my app folder:
cordova_plugins.js
cordova.js
/spec
spec.html
config.xml
/css
home.html
/img
index.html
/js
/res
Here is my config.xml code:

I have searched documentation, and haven't found any clue of why this isn't working, most answers to this question don't address version 2.9.0
Thanks in advance.
I know the question is about Phonegap 2.9, but that's the first thing Google spits when somebody looks for "phonegap alert not working". So here's what I did for it to work with Phonegap 3.0:
According to the manual, you need to add the plugin to your project. Just navigate to your project root folder and write this command:
$ phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-dialogs.git
After that, I added this to my html:
<script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
<script>
document.addEventListener("deviceready", onDeviceReady, true);
function onDeviceReady() {
navigator.notification.alert("PhoneGap is working", function(){}, "", "");
}
</script>
I'm using Phonegap 2.9.0 and the problem that i had is that I haven't add the script cordova.js to the page.
Also be aware that exist a cordova.js file specific to each platform so watch out of adding cordova.js from android on iOS.
Remember that all calls to the phonegap API should be done after deviceready has fired
try to add this feature to your config.xml file..
<feature name="Notification">
<param name="wp-package" value="Notification"/>
</feature>
..I hope that's help...
All you need is to add the plugin:
cordova-plugin-dialogs
Then use the alert function which will interrupt program flow:
alert("some problem here");
Works for iOS and Android.
