Is there a way to detect what platform the app is running on with Javascript in trigger.io? It looks like in the olden days there was an is.android and is.ios method that have since disappeared. We have some different behaviors we want to apply to the different browsers.
Yes, the forge.is namespace allows you to detect the platform using JavaScript.
To detect if the app is running on an Android device call forge.is.android()
To detect if the app is running on an iOS device call forge.is.ios()
See the Platform Detection docs for more information.
depending on your needs there are a few answers.
The isAndroid or isIOS can work for detecting simply the device but will not give you the version number, somtimes you need to detect versions of IOS or android.
To do that you should use the platform module

I've been working with the flutter sensors plugin and works pretty well until I lock the screen.
What I'm currently doing is listening the accelerometer events and create a post request after that.
I need to do this even with the screen locked, or even better, with the app running in background.
Do I need to create a MethodChannel and go native? or there is any way to do this with flutter?
You'll likely need to use platform channels considering you want to do this in the background. This would require operating on a separate isolate. There is an article listed in the documentation though I know others have had issues with it functioning on iOS and it's using objective c rather than swift.
I am working on an iOS app that integrates with multiple bluetooth devices (e.g. printers and barcode scanners). Each of the devices comes with it's own version of SDK and most of them just have objective-c/swift SDKs but not javascript SDKs.
Would like to find out what is the best way to reduce the app bundle size at the same time supporting multiple devices ?
Based on my investigations,
iOS doesn't allow downloading objective-c/swift code dynamically during runtime, hence the option of downloading the SDKs after the user having installed the app is ruled out.
Would like to get a feedback on the feasibility of the below solution. Also let me know if there is a better solution.
iOS version 8+ support embedded frameworks - Have separate iOS driver
apps for each of the supported devices which just installs the device
SDK as a shared embedded framework so that the parent app can
dynamically link to the shared embedded framework if one that matches
the connected device is available, otherwise force the user to
download the respective driver app.
This question has gone unanswered for a little while, so you may have already figured this out, but no, you cannot make shared embedded frameworks on iOS. Only Apple can do that. All of the frameworks you use must be either provided by Apple or embedded inside your app.
I have developed a web application using angularjs, now i want to convert ios application with iBeacons device searching functionality.
Is it possible to do this, any one please give me advice on this?
Yes this is possible, you can repurpose your Angular single page app into a Cordova/PhoneGap container, then use appropriate plugins (which bridge platform specific native code to Javascript) to add iBeacon or other beacon support. If you don't find plugins that do what you want, you can create your own if you are comfortable working in the native languages of the platforms you want to use (Java for Android, Objective C or Swift for iOS).
Example plugins that already exist to help with this would be:
cordova-plugin-ibeacon
ngCordova Cordova Beacon
There's an example of how to go about this using Angular JS / Ionic framework here.
There is no way to directly scan for beacons in JavaScript. This is true whether you are talking about a web app running in Mobile Safari on iOS or inside a UIWebView container within a native iOS Web app.
If you want to combine JavaScript-based apps with beacons, the alternative is to build Hybrid apps using technologies like Cordova or Ionic (which is built off of Cordova). You can then use Cordova plugins that let you interact with native code that does the beacon scanning, and pass it back to your JavaScript application. One such plugin that accomplishes this is here:
https://github.com/petermetz/cordova-plugin-ibeacon
There are limitations with this approach. Beacon scanning typically has to be in the foreground, and you can't really wake up the app on beacon detection.
Full disclosure: I am the lead developer on the Android Beacon Library open source project upon which the above plugin is based.

Judging by the contents here, it seems that we can specify different native stores in the related_applications
What should the pattern be for chrome browsers installed in iOS? Is that something supported currently?
The system is designed for future extension for other platforms to be able adopt it. Right now we don't support this in iOS and we don't have a timeline or plans to support it in the near future.
I'm making an app for jailbreak that lock the device when the user launch the app. I've tried GSEventLockDevice(); from GraphicsServices.framework but this does not work properly because it locks the screen but does not power off the screen. Is there another way to lock the screen without MobileSubstrate?
Just as another alternative, check out this answer, which uses SBDimScreen(). You could use that in conjunction with GSEventLockDevice().
It appears that you may now (iOS 5+) need to add an entitlement to your app to use this call successfully. If you haven't done that before, here is an example of how to do so. Obviously, in this case, the entitlement in question must be changed to com.apple.backboard.client.
You also might see if #VictorRonin has experimented with this, as he commented on the question I linked to. I tested SBDimScreen() on a jailbroken iOS 4.2.1 device, but my newer devices are currently unavailable to run this test. I'll try it later on iOS 5.x and post an update.
Note: the answer I linked to from Elias has a different call altogether for iOS 6.
Look at these several questions:
Simulating System Wide Touch Events on iOS
Simulating System Wide Touch Events in iOS without jailbreaking the device
How to send a touch event to iPhone OS?
The idea is that you can simulate system wide events. One of events is power down event. If you simulate it, it will turn off device and will lock it.
BTW. You may be interested to google more on GSEvent which is the key for even simulation.
Here are couple of useful links:

Also, this approach isn't limited to jailbroken phones. It works on jailed phone too (however, you won't be able to post it to AppStore).
