Re: Using NSPropertyListSerialization with NSArray of NSDictionaries




Ok I found my inevitable dumb mistake in this - could be helpful to someone out there...


The dictionaries I was trying to serialize used to include the return value of [myDocument fileName] to record some provenance information. After seeing that fileName is slated for deprecation in favor of fileURL under the Tiger docs, I dutifully changed fileName to fileURL in a number of places. The problem is that, while fileName returns an NSString (which can be serialized), fileURL returns an NSURL (which can't). Changing things to get rid of the NSURL in the dictionary solved the problem.

It would be very useful for us to store an ordered array of dictionaries using NSPropertyListSerialization. The code below works fine if processingInfo is an NSDictionary, but fails with the message "Property list invalid for format" if processingInfo is an array of dictionaries.


Is there any other reasonable way to do this? The docs say that as long is everything is an array, dictionary, number, string, or date it should work. Should I file a bug?

Thanks for any hints,

Rick

if (processingInfo) {

xmlData = [NSPropertyListSerialization dataFromPropertyList: [processingInfo objectAtIndex:0]
format:NSPropertyListXMLFormat_v1_0
errorDescription:&error];
if (xmlData) {
char *str = malloc([xmlData length]+1); // Add trailing '\0'
memcpy(str,[xmlData bytes],[xmlData length]);
str[[xmlData length]] = '\0';
miattputstr(mincid, varid, "processingInfo", str);
free(str);
} else {
NSLog(error);
[error release];
}
}
