  • Sets a custom key and value to be associated with subsequent fatal and non-fatal reports. When setting an object value, the object is converted to a string. This is typically done by using the object’s description.

    Declaration

    Objective-C

    - (void)setCustomValue:(nullable id)value forKey:(nonnull NSString *)key;

    Parameters

    value

    The value to be associated with the key
    key

    A unique key

  • Sets custom keys and values to be associated with subsequent fatal and non-fatal reports. The objects in the dictionary are converted to strings. This is typically done by using the object’s description.

    Declaration

    Objective-C

    - (void)setCustomKeysAndValues:(nonnull NSDictionary *)keysAndValues;

    Parameters

    keysAndValues

    The values to be associated with the corresponding keys

  • Records a user ID (identifier) that’s associated with subsequent fatal and non-fatal reports.

    If you want to associate a crash with a specific user, we recommend specifying an arbitrary string (e.g., a database, ID, hash, or other value that you can index and query, but is meaningless to a third-party observer). This allows you to facilitate responses for support requests and reach out to users for more information.

    Declaration

    Objective-C

    - (void)setUserID:(nullable NSString *)userID;

    Parameters

    userID

    An arbitrary user identifier string that associates a user to a record in your system.
