Error codes
Last updated：2022-03-31 11:59
The newly released In-app Chat 2.0.0 has been upgraded considerably (for detailed changes, see Release notes). If the version of the SDK you are using is earlier than 2.0.0, for its error codes, see Error codes for In-app Chat 1.x.x.
For a better development experience, we recommend you use the latest version of SDK.
Overview
This document provides possible causes and solutions for the network errors or the errors that you may encounter when running the latest version of SDK.
If the errorCode field exists in the result after the method is called, which indicates that an error occurs. And the code will be like this:
- (void)zim:(ZIM *)zim errorInfo:(ZIMError *)errorInfo{
NSLog(@"errorCode%lu,%@",(unsigned long)errorInfo.code,errorInfo.message);
