Return Value of [NSDictionary initWithContentsOfURL]
An initialized dictionary—which might be different than the original receiver—that contains the dictionary ataURL, or
nil if there is an error or if the contents of the resource are an invalid representation of a dictionary.Discussion of [NSDictionary initWithContentsOfURL]
The dictionary representation in the file identified by path must contain only property list objects (
NSString,NSData, NSDate, NSNumber, NSArray, or NSDictionary objects). For more details, see Property List Programming Guide. The objects contained by this dictionary are immutable, even if the dictionary is mutable.
