How do I clear the data in a plist created in Xcode?

I have been using a plist to store data in my app. I have been able to write and read from the plist with no problem. I created this plist in Xcode, adding the rows of numbers, dictionaries, and arrays myself. However, I would like to be able to reset the plist to the original state, and there must be an easier way to do this than writing a 0 or nil value to every entry in the plist. So what is the easiest way to reset the plist to its initial default state?

The simplest thing would be to delete the file using NSFileManager, like this:

[[NSFileManager defaultManager] removeItemAtPath:plistPath error:NULL];

Or if you don't want to do that, assuming the plist is a dictionary, just load the one from your application bundle and then overwrite the one in your documents, like this:

NSDictionary *originalPlist = [NSDictionary dictionaryWithContentsOfFile:bundleFile];
[originalPlist writeToFile:documentsFile atomically:YES];

Which will overwrite the saved file with the original file.

You could also try to just rename your Plist. Thats the least work i think.

 NSFileManager *fileManager = [NSFileManager defaultManager];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:@"mobile-watchlist.plist"];
    [fileManager removeItemAtPath: fullPath error:NULL];
