  • 0

In my application, I am trying to serialize a server response dictionary and writing it to file system. But I am getting error “Property list invalid for format” for some responses. The reason is CFNull objects in the server response. Now, the server response will keep on changing so I do not have a definite way to remove CFNull objects (). Below is my code:

NSString *anError = nil;
NSData *aData = [NSPropertyListSerialization dataFromPropertyList:iFile format:NSPropertyListXMLFormat_v1_0 errorDescription:&anError];

What is the best way to tackle this issue? How can I remove all CFNull objects from server response in one shot?

    I switched to NSKeyedArchiver option. Little slower than NSPropertyListSerialization but takes care of NSNull/CFNull objects.
