There is set of error categories which is returned by PubNub client through API completion blocks or delegate callbacks. Access to category can be done using status category property.
Delegate callbacks related to subscribe API usage and allow to handle real-time updates and errors.
|The SDK will announce this error when the Access Manager does not allow the publish to a channel.|
|PubNub API server was unable to parse SDK request correctly. A big chance of internal SDK error, so let us know if you stumbled into it.|
|Default category for successfully completed transactional request.|
|Processing has failed because of request time out.|
|Failure to establish a connection to PubNub due to a timeout.|
|The server responded with a bad response error because the request is malformed.|
|A subscribe event experienced an exception when running. The SDK isn't able to reach the PubNub Data Stream Network. This may be due to many reasons, such as: the machine or device isn't connected to the internet; the internet connection has been lost; your internet service provider is having trouble; or, perhaps the SDK is behind a proxy.|
|The SDK was able to reconnect to PubNub.|
|SDK subscribed with a new mix of channels. This is fired every time the |
|Previously started subscribe loop did fail and at this moment client disconnected from real-time data channels.|
|Returned when the subscriber gets a non-200 HTTP response code from the server.|
