Question

Stackoverflow fellows.

I’m trying to load a plist. But then plist‘s root can be NSArray or NSDictionary. Is there prettier way to determine which one it is (by the header’s type of root) NSArray or NSDictionary? Obviously, It is very common pull up file from NSDictionary or NSArray or NSData.

Thanks.

Answer 1

By using the NSPropertyListSerialization class you can deserialize your plist file from an NSData and then with a fast check understand if it’s a NSDictionary or a NSArray through isMemberOfClass:

id plist = [NSPropertyListSerialization propertyListWithData:data options:0 format:nil error:nil]

if ([plist isMemberOfClass:[NSArray class]]) {
  ..
}
