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 :
- (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];
}
});
}
Let me check into this for you @Jeremie PERERA…
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
