What are the iOS error codes and what do they mean?

The AppLovin SDKs return errors as integer codes. To make this more manageable, there are also a set of named constants that correspond to these codes. This gives you the flexibility to check for errors using the named constants. Here is an iOS example:

-(void)adService:(ALAdService *)adService didFailToLoadAdWithError:(int)code
{
   if(code == MAErrorCodeNoFill)
 {
   [self foo];
}}

If you are checking for the specific error returned, we recommend using these named constants rather than the integers in your code. For a list of these error codes and constants, see iOS > Overview > Error Codes in the MAX Integration Guide.
