Data Structure

NSUserDefault

There aren't so many things other than some settings. Saved as key-value pairs.

{
    "autoFocus": BOOL,
    "userIsLoggedIn": BOOL
}

Cache

Currently I simply cache data by archiving id into NSData and save them to Cache directory through writeToFile: method.

Draft

Drafts are saved in SQLite database /Documents/draft.db, which consists of 2 tables: Question and Answer. I use FMDB to operate SQLite database and all methods are extracted in wjDatabaseManager class, through which SQLite queries and NSObjects are converted to each other.

Question Draft

• questionTitle String
• questionDetail NSAttributedString
• topicArrData NSData: NSKeyedArchiver-archived NSArray
• attachAccessKey NSString
• anonymous NSInteger
• time NSDate

Answer Draft

• questionId NSString
• answerContent NSAttributedString
• attachAccessKey NSString
• anonymous NSInteger
• time NSDate

In database, NSInteger should be converted to NSNumber. NSAttributedString and NSArray should be archived to NSData through NSKeyedArchiver. NSDate should be converted to NSNumber as UNIX timestamp.

Acknowledgements

I would like to extend my sincere gratitude to the included open-source projects, without which this project would never be completed.

To meet specific demands of this project, some open-source projects were modified manually and forked into my own repositories instead of being managed by CocoaPods.
