Question

I have NSData that I’m loading from a filePath. The data is then getting passed around and I need the filePath for where the data came from.

What’s the easiest way to do this short of passing the filePath around as an extra parameter?

Answer 1

Wrap both in a container object that represents the file, e.g.

@interface File : NSObject

@property (strong) NSData *fileContents;
@property (copy) NSString *filePath;

// perhaps, even a nice constructor to fill these properties
- (id)initWithFilePath:(NSString *)filePath;

@end
