Hey y'all,
I'm trying to open my iTunes xml library. easily viewable in
PropertyList editor, the root object is a Dictionary.
I swiftly got it as an NSData, but now i'm trying to figure out how to
get it out of that.
i try using this: NSPropertyListSerialization method:
+ (id)propertyListFromData:(NSData *)data
mutabilityOption:(NSPropertyListMutabilityOptions)opt
format:(NSPropertyListFormat *)format errorDescription:(NSString
**)errorString
NSData *data = [NSData
dataWithContentsOfFile:[@"~/Music/iTunes/iTunes Music Library.xml"
stringByStandardizingPath]];
NSDictionary *plist = [NSPropertyListSerialization
propertyListFrom
Data:data
mutabilityOption:NSPropertyListMutableContainersAndLeaves
format:NSPropertyListXMLFormat_v1_0
errorDescription:@"blah"];
and get a:
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000064
Thread 0 Crashed:
#0 0x9013f354 in _CFPropertyListCreateFromXMLData
#1 0x90180484 in CFPropertyListCreateFromStream
#2 0x90844650 in +[NSPropertyListSerialization
propertyListFrom
Data:mutabilityOption:format:errorDescription:]
the errorDescription is obviously wrong and is possibly the trouble.
the java version specifies a String[]
i will say that the docs need an extra sentence there.
trying:
NSDictionary *plist = [NSKeyedUnarchiver
unarchiveObjectWithFile:[@"~/Music/iTunes/iTunes Music Library.xml"
stringByStandardizingPath]];
gives:
[NSKeyedUnarchiver initForReadingWith
Data:]: incomprehensible archive
version (-1)
help greatly appreciated.
