Purging Documents Directory in iOS

Your local sandboxed Documents directory may get stuffed with a bunch of garbage. To purge the directory and it's contents use this simple method:

- (void)purgeDocumentsDirectory

{

    NSLog(@"Purging Documents Directory...");

    NSString *folderPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

    NSError *error = nil;

    for (NSString *file in [[NSFileManager defaultManager] contentsOfDirectoryAtPath:folderPath error:&error]) {

        [[NSFileManager defaultManager] removeItemAtPath:[folderPath stringByAppendingPathComponent:file] error:&error];

    }

}
