Discussion

Raises the exception with the given format.

This is a shortcut for raise:format: method and makes exception creation code much less verbose. As we don't use specialized exception names, this makes sense...

raise:format:

Raises the exception with the given NSError object.

+ (void)raise:(NSError *)error format:(NSString *)format

Parameters

error
The error that describes the reason.
format
A human readable message string explaining the context of the error.
...
A comma separated list of arguments to substitute into the format.

Discussion

Raises the exception with the given NSError object.

This is useful for converting NSError s into NSException s. The method allows the client to pass in additional context information which further aids diagnosting the exact reason for the exception. If no context information is desired, pass nil and only error information is used for formatting. As exception message can become quite verbose, it is split into several lines to make the output more readable.
