Question

I am fairly new to archiving an object I have. I have a dictionary that I want to archive.. so first I got the path by doing:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        dictionaryPath = [paths objectAtIndex:0];

so is the next step to append this dictionaryPath with a .txt? Or should I create something first at this directory? What is then the data type?

I want to be able to use it for:

[NSKeyedArchiver archiveRootObject:locationDic toFile:dictionaryPath];

Where dictionaryPath is the path to store this NSDictionary

Answer 1

NSSearchPathForDirectoriesInDomains will give you an array of directory paths. So if you take the first one, you need to append a filename (whatever filename you’d like, with whatever extension you’d like), and then use that path as the location to write out to.

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 NSString *documentsDirectory = [paths objectAtIndex:0];
 NSString *dictionaryFilePath = [documentsDirectory stringByAppendingPathComponent:@"Filename.extension"];
 [NSKeyedArchiver archiveRootObject:locationDic toFile:dictionaryFilePath];
