How to control upload extension initiated from controller center? - ios

I implemented upload extension and setup RTMP server for broadcasting via upload extension. The broadcasting is initiated from control center, not through SetupUI extension. Since the SampleHandler.m doesn't provide RPBroadcastController, I can't programmatically pause or stop the broadcasting. I'd like to at least stop the broadcasting and show error message that the server is not available. I've looking through all WWDC docs, but couldn't find much info. Mobcrush is showing error message like "Not logged in", how they do that?

I found a mistakes in my code, finishBroadcastWithError function should call [super finishBroadcastWithError:] to call RPBroadcastController to stop broadcasting and show proper error message. You don't need to access RPBroadcastController nor need SetupUI to controller broadcast. That was it, I wasted 2 days on this, I wish no one do that.

CallKit error com.apple.CallKit.error.requesttransaction error 7

I'm using Twilio voice quickstart code https://github.com/twilio/voice-quickstart-swift.
When I make a client to client call, call doesn't connect. CallKit runs in the background though, I can see the green notification bar when I send app in the background.
Following is the error:
StartCallAction transaction request failed: The operation couldn’t be completed. (com.apple.CallKit.error.requesttransaction error 7.)
As you can see Googling doesn't help as there doesn't seem to be any solution around?
Does anyone know how to fix or debug it further?
Updated:
Attaching VoIP settings, it's certainly enabled.
Problem is in your code which you write to handle and initialise variables. There is nothing wrong in the Twilio sdk either so don't look there. Anything which you are doing beyond twilio sample code is the place to look for the problem.
I've also wasted months of my time on similar issue and found out that there was issue with initialising one variable.
You are trying to request CXStartCallAction right after another CXStartCallAction was requested. You need to end the first call correctly.
In any case you must follow correct sequence of actions. Once you user wrong action in a sequence, CallKit will return one or another error.
And DO NOT request one action immediately after another is processed. There should be some time between two requests. For example, you initiated CXStartCallAction, then you checked that user is offline and trying to end the call. If that check is quick, then "end action" may result in error. You need to wait a few milliseconds before cancelling the outgoing call.

Have you enabled capabilities for Voice over IP in the project settings?
Try to initialize CXProvider and CXCallController sooner, before requesting CXStartCallAction
I had the same problem because the Provider and the CallController have been lazy loaded.
It looks like that the CXProvider initWithConfiguration runs asynchronously which means you need to call this early otherwise you run into the risk of having a call without the completion of the initWithConfiguration function.
Thanks to #Allen for pointing me in the right direction.

lua-lgi libnotify add_action callback not being called

I followed the hello world example on this page to set up lua-lgi and libnotify, successfully getting a notification that looks and acts the samea s if using os.execute("notify-send..."). Notify-send does not allow user actions, from what I've gathered, so I am attempting to directly use the libnotify library to display a notification with a button. When clicked in the notification, it should open a file. I am able to call the function described here with lua, using (building from the hello world example):
Hello:add_action("button", "Open", function(notification, action, user_data) os.open("gedit tmp") end)
which successfully displays a button with the label "Open" in the notification. However, the callback function is not called, so the file does not open. I also noticed when running the script, it actually finishes executing before the notification has fully appeared, so if the program is not running anymore when the button in the notification is clicked, then that's one reason why the callback isn't being called, if it's working correctly up until that point. This is my first experience with lua-lgi, so I'm not sure how these types of callback functions translate into lua, or if they're even supported, which is probably what I'm really trying to understand here. Any help is appreciated regarding this issue, or insight into an alternative to displaying a notification with a button and callback via other means.

com.google.GCKError Code=2 when connecting to ChromeCast device

I'm working on an iOS app where I now want to integrate ChromeCast support. I use the HelloGoogleVideoCast example to test my hardware setup and get inspiration for my app.
I have now stumbled on a problem that is present both in my app and in HelloGoogleVideoCast. When I connect to a device (connectToDevice method in HelloGoogleVideoCast) I get error "The operation couldn’t be completed. (com.google.GCKError error 2.)". I have power-cycled the device with no change in behavior. I never get to the callback deviceManagerDidConnect, instead deviceManager:didFailToConnectWithError is called with this error. Still, I can connect with the iOS YouTube app.
I can't find anything with substance if I google it and I can't find any good ChromeCast developer forums.
Is there anybody who has an inroad to how to solve this?
I m not sure it will help but u can try:
Download the Chromecast app from app store:
chromecast link
After u see your chromecast -> select your chromecast -> General -> make sure both check box are selected (I know the text is nothing to do with your problem).
Try now.
If the error still occur, try to reboot your chromecast.
If your error still occur, try to reset your chromecast, and then check the boxes again (don't forget!).
Make sure that you initialize the Receiver Manager in your receiver app as soon as possible. Don't wait for the window.onload. If the receiver takes too long to load and initialize the receiver manager, the connection is automatically torn down.
I had the same problem as you did and making the following changes on receiver worked for me:
I've put the script src="//www.gstatic.com/cast/sdk/libs/receiver/2.0.0/cast_receiver.js" inside head tag and before title tag;
I've put my script file which managed all cast functions after
body tag (actually I've put all script declarations, except for cast_receiver, after body tag, including jQuery);
I hope it can help you yet :)

Send SMS without presenting MessageComposeViewController in iOS

I am working on sending SMS demo. I want to send how to send the SMS and how to set the delegate to MessageComposeViewController. and in order to send the message we have below line
[self presentViewController:messageController animated:NO completion:nil];
This line will present the MessageComposeView on screen with SEND button. And Once we click on send button it sends the message. What I want is to send the message directly without presenting this MessageController on screen. Please help how can I do this.
In this related question, Apple has restrictions in place on being able to send a SMS message without the user clicking the SEND button.
Apple really wants the user to be in control of the SMS functionality of their phone. Otherwise all sorts of data could be flying off some random app (e.g. spamming your contacts with "try this app out!", which would not be very friendly nor very nice).
One of the answers in this question does have a potential non-MFMessageComposeViewController solution, however I have a feeling that if Apple catches you doing this they might deny your app from being approved for the app store.
You could send the message using some webservice on the internet. http://client.suresms.com/ProjectInfo.aspx?Info=3 or www.clickatell.com. They have bunches of API for sending messages.
In SureSMS simply create an account and make a http request to
http://suresms.com/Script/GlobalSendSMS.aspx?login=[youraccountnumber]&password=[yourpassword]&to=[phonenumber]&Text=Hallo.
Remember to URL encode the message text and use countrycodes. Thats it.
You have to present MessageComposeViewController.It's not possible to send without presenting it.
MFMessageComposeViewController has delegate method while delete/send/save. which only perform while we present it.
(void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
You can't do it without MFMessageComposeViewController. Apple won't allow to send SMS without user interaction.
As per document
You must not modify the view hierarchy presented by this view
controller. You can, however, customize the appearance of the
interface using the UIAppearance protocol.
I've alternate solution of this, Alternative way can be Using web service API. Create a web service at server side that send a message to specific number(s) that accept numbers as parameters with request.(according to your requirement)
As using Web server or external sms provider can do it.
It is NOT possible . Apple willn't accept your App. Apple will reject your App if you do like that. Human interface guidelines should be followed up.

How to handle UIWebView cases were no connection, and should I use Network indicator?

What´s the preferred way of handling an app that an integral part of it is using UIWebView, the first view the user sees when app is first loaded is a UIWebView trying to access a webpage... If the connection is slow or if there is no connection at all - how should I handle this?
also, does UIWebView require you to use the network indicator (spinner) when it´s using the network?
Always try to provide feedback to the user, it helps in increasing usability. So, yes spinners(activity and network indicators) are very useful. You might also learn a lot by looking at other apps as to how they handle network errors. Facebook for example shows a nice message saying "Network Unreachable, Try again". You can implement actions like this which will always let the user know how to proceed.
As to handling network connection, Apple provides Reachability class. Look at the attached example to understand how to implement this -
https://developer.apple.com/library/ios/samplecode/Reachability/Introduction/Intro.html
you can use activityindicator to show loading....
and then stop indicator in UIWebView delegate method
-(void)webViewDidFinishLoad:(UIWebView *)webView
