How to convert UIView object to NSData and vise-versa for saving it in database using sqlite

Question

I am using sqlite for my project which stores all the data including text fields , id , and one UIVIew object in a column having BLOB datatype .
Now while retriving the data i use
const char *raw = sqlite3_column_blob(selectstmt, 3);
int rawLen = sqlite3_column_bytes(selectstmt, 3);
NSData *data = [NSData dataWithBytes:raw length:rawLen];
  view =[NSKeyedUnarchiver unarchiveObjectWithData:data];
where data is NSData obj n view is UIView obj ,
also while inserting data  i use ,
NSData *data=[[NSData alloc]init];
    data=[NSKeyedArchiver archivedDataWithRootObject:view];
   // [data dataForView:notes.view];
    sqlite3_bind_blob(updateStmt, 2, [data bytes], [data length], SQLITE_TRANSIENT);
But this is not working properly ...  the Data object is giving some length,
while using the view the view object is null
is there any other solution to do the same ?

There's a ton of information here: [http://www.json.org/] and I can't believe you didn't find that site yourself.
