What is __NSCFArray
in this AFNetworking 2.0 response:
- (void)loadData:(NSMutableArray *) resDic
{
...
[operation setCompletionBlockWithSu
It is already an NSArray
, something you can verify by calling:
BOOL isKindOfArray = [responseObject isKindOfClass:[NSArray class]];
NSArray is implemented as a class cluster and one of the private subclasses that it might return is __NSCFArray
.
The point of a class cluster is that the framework can provide different implementations under the hood that you don't really have to care about. As far as you should be concerned, it's an NSArray.
NSArray
is a class cluster. This basically means that NSArray
objects could be made up of one of several different actual implementations and __NSCFArray
is one of the classes (probably the most common) that NSArray
can use to implement an array.
Just use the __NSCFArray
as you would any other NSArray
and it'll work fine.
