Hello,

I test my iOS app with Wowza SDK.

I see something wrong… :

When I switch wifi to 4G (cellular phone), the SDK trigger an error with the function : - (void) onWOWZError:(WOWZStatus \*) goCoderStatus

Do you know how i can reconnect the stream ? i try to do this : [self.goCoderstartStreaming:self];

But It doesn’t work…

Thank you for your help ! 🙂

It seems that when i wait 10 seconds before restart the stream, it works…

Can you tell me why ?

Is this solution is the best way ? :

My code :

```auto
- (void) onWOWZError:(WOWZStatus *) goCoderStatus {
// If an error is reported by the GoCoder SDK, display an alert
// that contains the error details using the U/I thread
	dispatch_async(dispatch_get_main_queue(), ^{
		UIAlertView *alertDialog =
		[[UIAlertViewalloc] initWithTitle:@"Streaming Error"
			message:goCoderStatus.description
			delegate:nil
			cancelButtonTitle:@"OK"
			otherButtonTitles:nil];
		[alertDialog show];

		if([networkConnectionWhileRecordingisEqualToString:@""])
		{
			_lSearchNetwork.text = @"Connexion dans 10 secondes";
			[self performSelector:@selector(startStreaming) withObject:@"" afterDelay:10.0];
		}
	});
}

```

Hello @Rose Power-Wowza Community Manager.

I always have this problem when my iOS lost the internet connection.

I am using AFNetworkReachabilityManager for the dection of the internet lost.

Then when internet is up, I detect id goCoder has no error, and i try to reconnect. sometimes, i get this error :

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Menlo; color: #000000; background-color: #ffffff}

**SendDelegateMessage(NSInvocation \*): delegate (webView:identifierForInitialRequest:fromDataSource:) failed to return after waiting 10.000000 seconds. main run loop mode: kCFRunLoopDefaultMode**

I am using the broadcast function with the MP4 writing.

So i can’t today handle the internet lost, this crash my app… do you have any idea ?

Ok I find a way :

Use the wowza status function to trigger a loss of internet connection.

And update the Wowza iOS SDK which resolve the problem that you can reconnect after a deconnection
