Question

I have an NSMutableArray of NSStrings, which I want to write to a text file, so that each string has its own line.

Any suggestions?

Answer 1

You can create a full string of your NSMutableArray with

- (NSString *)componentsJoinedByString:(NSString *)separator

Something like

NSString* fullString = [yourArray componentsJoinedByString:@"\n"];

You can then use

- (BOOL)writeToFile:(NSString *)path atomically:(BOOL)useAuxiliaryFile encoding:(NSStringEncoding)enc error:(NSError **)error

on the fullString to write it on disk.
