Details:
NSKeyedArchiver doesn't properly encode an NSData object's contents as a data
block. The reason for this appears to be that NSData is a class cluster but
NSKeyedArchiver fails to check for NSData's concrete subclasses (e.g.
NSDataMalloc) when encoding.
On line 248 in NSKeyedArchiver.m, the following check is performed to
determine if an object is stored directly:
if (c == [NSString class]
|| c == [NSNumber class]
|| c == [NSDate class]
|| c == [NSData class]
)
Adding the following additional conditions resolved the problem for me:
|| [c isSubclassOfClass:[NSString class]]
|| [c isSubclassOfClass:[NSNumber class]]
|| [c isSubclassOfClass:[NSDate class]]
|| [c isSubclassOfClass:[NSData class]]
