Store all custom data in NSDictionary or NSArray.

Now save dictionary or array with custom data in document directory follow this link

no Storing data on NSUserDefaults is not good, because it can cause a serious hack.

instead of it you can use AppDelegate to store data globally.

The better way would be to serialize it as a binary blob on disk using NSArrays writeToFile:atomically: or writeToURL:atomically:. NSUserDefaults aren't stored as binary and thus need extra parsing time upon loading, and extra time to write out to disk. NSUserDefaults is also not designed to hold large amounts of data but for a small set of settings data.

Although you can store this is NSUserDefaults using [[NSUserDefaults standardUserDefaults] arrayForKey:@"key"]; you probably shouldn't. Defaults was designed to store VERY small ammounts of data, like a users preferences (thus the name). If you wish to store more data than this, then you may want to look into .plists, NSDocumentDirectory, Core-Data, or SQLite databases.
