If you're like me, when you start testing a new SDK or service, you want to start building and prototyping straight away. While our SDK is simple to use, you still have to add your own UI to make a calling app that users will understand.
Today we are making this solution open source and you are free to use it as you wish. If you have any ideas, suggestions or changes, just push your changes here and we can make a fantastic UI kit to start using in your apps.
When we started to build this, we had the vision of being able to make an outgoing call with a great UI by writing as little as two lines of code: one line to start the client and one line to make a phone call to any number in the world.
I also wanted to have an unobtrusive design on the call screen so that it would not interfere with your own app design. We were really inspired by the native iOS 8 look that is both elegant and familiar to many app users.
It is worth mentioning that this framework is using ActiveBackground connections, so you must set the VoIP background mode and Audio background mode on your main app.
You can download the tar from here; we need to add here, or check it out and modify it on GitHub.
Using Sinch, there are only two lines of code needed to make outbound PSTN calls using our Voice API. If you want to support DATA-DATA with background calling, add one more line of code, which you can find in our documentation. When you use the framework, it will give your three screens, very similar to the calling screens on iOS 8.

In your app:
- Download the framework here and add it to you project as an embedded binary (sorry, iOS 8 only)
- In your AppDelegate.m, make sure you add the following lines of code, along with your key and secret
-(BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[CallingManager sharedManager]
startClientWithKey:@"key"
secret:@"secret"
userName:userName sandbox:YES
launchOptions:launchOptions];
return YES;
}
3. In your view controller where you want to make call, you probably have a button in a view that you want to enable for calling in that IBAction. Add the following code:
[[CallingManager sharedManager] callNumber:@"+4600000000020"];
Lastly, for background calling, add the following code:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
[[CallingManager sharedManager] handleLocalNotification:notification];
}
That’s it! We are really interested to know how you feel about these kind of libraries. Tweet me at @cjsinch or email me at christian@sinch.com to share your thoughts.
