使用CloudKit从Swift中的CKRecord中提取NSArray

Question

How can" I fill an NSArray (an array of strings) from a CKRecord?

I created the record successfully with: myPrivateDatabase.saveRecord

and I can fetch the record successfully with: myPrivateDatabase.fetchRecordWithID

I can see that the data is in the record with: println(returnRecord.objectForKey("key1")) in the form of comma delimited, quoted strings

But I can't figure out how to get that back into the NSArray

Help!

Thanks :-)

If you just put the array in a string field, then you have to parse it back.

let line = returnRecord.objectForKey("key1")
let values = line.componentsSeparatedByCharactersInSet(returnRecord.objectForKey("key1"))

then just loop through the values and remove the leading and trailing quotes. You do have to be aware that it will go wrong when you have strings that contains a comma. To solve that issue you should use NSScanner for parsing the line

Did you specify the field in CloudKit as a 'String List' or is it a String?
