Thanks for the reply Marco,
while archiving I use the following code:
data = [NSMutableData data];
archiver = [[NSKeyedArchiver alloc] initForWritingWithMutable
Data:data];
[archiver setOutputFormat: NSPropertyListXMLFormat_v1_0];
[archiver encodeRootObject:_myRootObect forKey:@"RootObject"];
[archiver finishEncoding];
result = [data writeToFile:@"archive.xml" atomically:YES];
[archiver release];
to decode it I used:
_myRootObject = [NSKeyedUnarchiver unarchiveObjectWithFile:@"archive.xml"];
after this line _myRootObject is nil. If on the other hand I archive/dearchive
using:
[NSKeyedArciver archiveRootObject: _myRootObject toFile:@"archive.bin"];
_myRootObject = [NSKeyedUnarchiver unarchiveObjectWithFile:@"archive.bin"];
it works!
can you maybe help out in detecting what I'm doing wrong. The only thing I can
imagine is that the NSKeyedUnarchiver is looking for a binary file but it finds
an XML file and doesn't now how to deal with it.
