Discussion
This method returns nil if the data object could not be created. If you need to know the reason for failure, use dataWithContentsOfFile:options:error:.
This method is equivalent to calling dataWithContentsOfFile:options:error: and passing no options.
A sample using this method can be found in Working With Binary Data.
