NSArray
mythodeia opened this issue · 5 comments
Hello and thanks for the great source code.
I have a question. How can i handle an NSArray in the testrecord for example in your demo?
as i see it i need to add the column in the testtable.m file as well.
how will i add the array in the table?
thanks
the testrecord is extended from CTPersistanceRecord
, but actually, you don't have to do this.
Any object who confirms to CTPersistanceRecordProtocol
can be a record, and can be accepted by CTPersistance
, even a customized UIView.
so, in your case, you can implement an object who confirms to CTPersistanceRecordProtocol
, in - (void)objectRepresentationWithDictionary:(NSDictionary *)dictionary;
and - (NSDictionary *)dictionaryRepresentationWithTable:(CTPersistanceTable <CTPersistanceTableProtocol> *)table;
you can handle NSArray.
thanks a lot for your answer.
Can you add this case in your existing demo project for everyone to have?
great project
👍
I think CTPersistanceRecord
is the very case of this...
as i see it i should add the array in the - (NSDictionary *)columnInfo method too.
so should i save the NSArray as a BLOB in the table?
you can save the array data as a json string, and when you get data from database, you parse this json string into NSArray, while in - (void)objectRepresentationWithDictionary:(NSDictionary *)dictionary
.
though sqlite support blob and CTPersistance
is based on sqlite,I do not want to support blob type in first place, because I think all blob data like image should be saved as a file, and we save the path of image file in database.
