Communicating between ios apps - ios6

I hav got two ios apps..app1 and app2. Now what i want is to start app2 from app1. this can be done using openUrl method and url schemes. But i want to launch app2 only when app1 goes to background/is suspended.
I am able to launch app2 from AppDelegate's applicationWillEnterForeground...but same code is not working in AppDelegate's applicationDidEnterbackground method or applicationWillResignActive.
Can anyone tell me how to launch app2 from app1 when user leaves app1.
On checking the logs, it shows following:
: Entitlement com.apple.springboard.openurlinbackground
required to use BOOL _verifyURLEntitlement(mach_port_t, NSURL ,
SBSApplicationLaunchFromURLFlags, SBApplication *) from background
app : LaunchServices: application launch failed - received
error code 1

First of all, Iron Man gave a good link, which is applicable only for jailbroken devices.
Secondly, there is no legal and documented way to do this. Apple mantra is that users decides what should a device do. In this case, a user pressed Home button, so it shouldn't randomly go to some other app.
Potentially you can find some private API which will allow you to do something like that. However, it won't be accepted in app store.

iOS11 location update after getting killed by user

I'm implementing a non VOIP app in iOS 11. As per the nature of my App, I've implemented the startMonitoringSignificantLocationChanges(). All the implementation went well and it is working now.
while terminating the app I'm calling startOrReStartSignificantLocationUpdate()
and I'm restarting significantlocationupdate in didFinishLaunchingWithOptions
also I'm updating location in server in didUpdateLocations event
Location updates is reflected on my server when the App is in foreground or background. It is now reflects even if user kill the App manually. So it works with SLC but
the problem is;
Updates seems to get stopped after a period of time say, 3 - 4 hours. It happens if the user kills the App manually. As per the nature of my App, I need to get it re-initiated up on location change and get the location update to my server.
Is there any category of App which can get this location updates forever in iOS11? I'm thinking about how Moves App in iOS works. Not sure it works perfect with iOS11 though
If you only use “While Using” location access, as far as I understand nothing changes for you. If you use the “Always” access though, and you didn’t provide a “While Using” fallback as you should have… well, you will need to do that now
As Brad Jensen explains in the WWDC talk I mentioned, Apple has decided that forcing the user to give the app “Always” location access is a bad user experience:
Now, a second reason we think that many developers choose to require
Always authorization is they’re simply trying to give their users the
best possible experience (…) but this makes for a very poor user
experience for the users that don’t wish to grant the app Always
authorization. They are forced to choose between granting the app
Always, which is more than they would like in this example, or
granting it Never, which means they don’t get to benefit from any of
the app’s location-based features. And their final option is to grant
it Always and then revoke that authorization after they’re done using
the app. In any case, the user is not having a great time with this
app.
So, when you build your app using the iOS 11 SDK, you are now required to provide an NSLocationWhenInUseUsageDescription key in all cases (if you use location at all). For “Always” access, you can additionally provide a second key, which is now called NSLocationAlwaysAndWhenInUseUsageDescription. If you only provide NSLocationAlwaysAndWhenInUseUsageDescription but not NSLocationWhenInUseUsageDescription, asking for “Always” access will not work:
This app has attempted to access privacy-sensitive data without a
usage description. The app's Info.plist must contain both
NSLocationAlwaysAndWhenInUseUsageDescription and
NSLocationWhenInUseUsageDescription keys with string values explaining
to the user how the app uses this data
Effect on existing apps
Most SDK changes usually only take effect once you recompile your app with the latest version of the SDK & Xcode. This one is different: even if you don’t release any updates this summer, this change will affect you.
Here’s what the user sees when they run existing apps from the App Store in iOS 11 beta and they ask for location access:
The first one is from Foursquare, which has provided both access level options for a long time. In this case, iOS 11 lets you immediately choose “While Using” or “Always”, and since the description texts have not yet been updated with the new behavior in mind, it shows both texts at the same time.
The second one is from Topo Maps, an app that lets you browse hiking maps and find yourself on the map while you’re on the trail. You can imagine it has no reason to track you in the background, but still, the developer has not provided a “While Using” option. iOS 11 now lets you choose that option anyway, but since it might possibly cause some unexpected behavior in the app, it shows a warning that some parts of the app might not work.
If your app has only provided an “Always” key so far, I’d recommend that prepare a transitional update that adds the NSLocationWhenInUseUsageDescription key and makes sure the app works properly in this mode. That way, the user will get a popup like the one in Foursquare, which at least looks less scary.

Open nuke software through chrome?

How to open a desktop application(like Nuke) through browser.
for example: RV software have a url protocol. we can use that (rvlink://).
I think this is what you're looking for:
https://support.shotgunsoftware.com/hc/en-us/articles/219031308-Launching-applications-using-custom-browser-protocols
Note that this is asking your operating system to "launch the thing registered with the requested custom browser protocol". Similarly you can have a hyperlink mailto:/// which opens the email application registered on the users computer. rvlink:/// is registered by RV as one of these custom browser protocols during it's installation.
If you want more control you would need a process running on the user's machine that you interact with. For example that's the approach shotgun's competitor ftrack took leveraging a local process they call ftrack connect (http://ftrack-connect.rtd.ftrack.com/en/0.1.17/developing/tutorial/custom_applications.html)
If you want to run something completely custom you could take a look at running your own RPC. You would initiate the registered RPC command from the web application. Check out http://www.zerorpc.io/ or https://crossbar.io/ for some more information.
Good luck!
I spotted in an earlier response of yours that you're using Shotgun and it's launch in RV features. In which case - are you aware of Shotgun Toolkit?
https://support.shotgunsoftware.com/hc/en-us/articles/219039788-Toolkit-Home-Page
It provides app launching via the website, which it accomplishes via Shotgun desktop (a desktop app). It used to work via a browser method that chrome etc moved away from so now requires the desktop app hook.
There's actually a huge amount that SGTK does, though I think you might be able to disable everything except the app launching if you wanted. We've got it implemented across 4 locations here and it's pretty decent.

How to implement push notifications in React Native when the app is closed

I'm studying React Native right now, and I'm trying to figure out how to enable the reception of Push Notifications even when the app is closed, just as Facebook does.
I'm a web developer, so I'm not used to mobile apps' "Manifest" logic. Where should I start from?
Thank you!
It seems that since you are a web developer, mobile app is not yet familiar with you. Actually, setting up push notification will require a few more official steps (differently on iOS and Android), and after everything is set, the push notification will happen between Apple server (or Google server) and smartphone's OS (which is iOS or Android), so the push notifications will come to the phone no matter what (without knowing/caring your app is opened or closed ^^)
In the programming code of our app, we can do our logics when the notifications come based on 2 cases: users is using the app or app is not running (not running means users are not using your app, and it is either staying awake in the background or users have exited it completely - e.g. pressing Home button twice on iPhone, and swiping the app away)
Actually, If you want your app to stay awake in the background, you can add some settings to the "manifest"-like files (of course differently on iOS & Android). However, my experiences taught me that keeping the app awake will encourage the users to complain and delete our app (my previous app's user once complained about his iPhone's battery was consumed greatly because of my app ^^)
If you really want to keep your app awake, you can set it in the settings, then in the push notifications' data, you can include extra parameters, and finally in the function of receiving push-notifications in your app, you can do anything with those parameters!
In short, you may just need to config push-notification properly for your app, and Apple/Google will do the rest, either your app is running in background or totally closed, it will receive the notifications. Hope you can find a good solution based on my explanation. If there's still something unclear, feel free to post here some more details on your needs, thanks!
This is the library I'm using with my previous react-native project: (they also have tutorial there ^^)
https://github.com/zo0r/react-native-push-notification
ADDED EXPLANATION: (based on author's needs):
The goal is: the user will register/login in the app, and will subscribe to some future events.
=> whenever users open the app, data will be sent to Apple/Google server to get a token, and you will use this token together with user's subscribe data to send all to your own push-server (you can use PHP or node.js server or whatever)
When an event gets updated a notif. should be sent to all the users who are going to that event. So a notif. aimed to certain users only.
=> like the above answer, data will be sent every time users open app (or change settings, you can do it in your logic of the app, because data will be kept your own push-server, which means on that server, you can even see user list, and can aim to certain users - it depends on what data will be sent to the users from the smartphone, but users may refuse inputting too much information like name, age or email, but it's up to your service's need ^^)
By clicking on it, the app will open and a certain page of the app (pre-existing) will be shown.
=> by default, when an notif. is clicked, the app will be opened for sure, and here once again, you can add extra parameters to the notifications (which is the landing page you need, then in the function of you app, just go there - but it may get extra logics for this. Besides, when to push notification, and which data should be pushed etc. will be controlled by your own server)
It seems like the most complicated part will be the "sending to certain users" one!
=> I explained this already, but you're right, actually it's complicated, because you need to create your own server with lots of API and logics based on your needs, and it need a few more steps (complicated one because you need to register many things with Apple & Google, then adding their Certificates into your own server etc.)
Hopefully you will achieve it, I suggest you play around and truly understand how push-notifications work first (for both sides - your own server and your application) - Good luck, though ^^

WindowsStoreApp Failed certification,saying the App failed Touch Input

My WindowsStoreApp certification failed(not the first submission) in Windows Store recently. The Note from testers says
The app is not usable with touch input and no such limitation is
disclosed in the app description page. Please see:
http://msdn.microsoft.com/en-us/library/windows/apps/Hh761498.aspx
for some of the common interactions for keyboard, mouse and touch.
I dont have a Windows RT device to test, instead I test my App in a windows 8 PC. I used 'POINTER PRESSED' Event in my App for Navigations,calculations,etc. I had successfully uploaded this App to the store a lot of times,but this time it failed. I am confused. My App should support all sort of WindowsStore Devices.Please guide me.

Subscriptions Not Receiving Timeline Notifications

Steps to Reproduce (unexpected behavior in bold):
I successfully create an app contact via the Python Starter App
I successfully subscribe to timeline notifications
I take a photo with Glass
I share that photo with my app contact
The photo is duplicated on the timeline
The app's callbackUrl is never pinged (yet POSTing manually via curl works fine)
Attempting to delete the duplicated photo card makes the Glass OS glitch out until reboot
Posting some sample code with actual URLs may help us spot a possible error, but two things you may want to look into as you're debugging:
Don't forget that the URL in your contact must be HTTPS. HTTP URLs are not supported.
Check the contact object that is returned when you create the contact. It may be worth checking to make sure the URL and everything else is as you expect it to be... and then test against THAT URL.
Can you also clarify what you mean by "glitch out" in this case?
