Question

How do I save an NSString as a .txt file on my apps local documents directory (UTF-8)?

Answer 1

Something like this:

NSString *homeDirectory;
homeDirectory = NSHomeDirectory(); // Get app's home directory - you could check for a folder here too.
BOOL isWriteable = [[NSFileManager defaultManager] isWritableFileAtPath: homeDirectory]; //Check file path is writealbe
// You can now add a file name to your path and the create the initial empty file

[[NSFileManager defaultManager] createFileAtPath:newFilePath contents:nil attributes:nil];

// Then as a you have an NSString you could simple use the writeFile: method
NSString *yourStringOfData;
[yourStringOfData writeToFile: newFilePath atomically: YES];
