문제

I have this code in my project:

id mappedData = [dataWithContentsOfMappedFile: path]

Obviously, if mappedData is nil it didn't succeed. But how can I get details about why it didn't succeed? There's no dataWithContentsOfMappedFile:withError:.

도움이 되었습니까?

해결책

Use -dataWithContentsOfFile:options:error:, passing the NSDataReadingMapped constant in the options parameter.

(This constant is known as NSMappedRead if you're not compiling against the iOS 4.0 SDK.)
