How to keep the screen on an iPhone with Phonegap 2.7

问题

I do an ios application (ios6) with cordova 2.7 which use the GPS and I need that the screen of the Iphone is always on. I want to avoid the phone from sleep.

I tried to install this plugin https://github.com/phonegap/phonegap-plugins/tree/master/iOS/PowerManagement but apparently it is too old.

How do that?

If you're willing to get your hands dirty, this can be quite easy to fix, by making a Cordova Plugin.

If you haven't made a Cordova plugin, it is definitely a skill that you should master, as not all functionality is available through PhoneGap plugins yet, and it can frequently be quite easy to make it work. The full details are available in the PhoneGap Plugin Development Guide.

For this, your JavaScript side of the plugin would be something like

cordova.exec(function(winParam) {}, function(error) {}, "myPlugin", "preventSleep", []);

In this case, your PhoneGap would look for a method named preventSleep in the myPlugin class.

Next, your preventSleep method would look something like

- (void)preventSleep:(CDVInvokedUrlCommand*)command
{
    [UIApplication sharedApplication].idleTimerDisabled = YES;

    CDVPluginResult* pluginResult = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK];
    [self.commandDelegate sendPluginResult:pluginResult callbackId:command.callbackId];
}

Now you could make a corresponding method like allowSleep that set [UIApplication sharedApplication].idleTimerDisabled = NO;

Here's an up-to-date plugin also supported by PhoneGap Build: https://github.com/EddyVerbruggen/Insomnia-PhoneGap-Plugin

I've updated this plugin for more recent versions of Phonegap (2.5 to 2.9) - you can find the source code and my XCode test project in my answer to this question.

Are you sure you want to keep the screen on all the time? Apple are fairly strict on when this is allowed and may reject your app if it's not for a good reason. If you just need to allow you app to keep running and receive position updates in the background, this can be done without a plugin by adding the following to your project .plist:

<key>UIBackgroundModes</key>
<array>
  <string>location</string>
</array>

Or in XCode, open the .plist and add the key "Required Background Modes" and value "App registers for location updates"

I'm not sure if you've already seen this but it looks like there's a plugin available for iOS on phonegap build, apparently an android version is coming out soon.
