Either of these would allow you to do what you want for NSArray:
- (NSArray *)sortedArrayUsingComparator:(NSComparator)cmptr;
- (NSArray *)sortedArrayUsingFunction:(NSInteger (*)(id, id, void *))comparator
context:(void *)context;
And these for NSMutableArray:
- (void)sortUsingComparator:(NSCom
In that array of sort descriptors, you'd need to pass two of them. The first to
sort by type and the second to sort by date. The second sort descriptor would
only be used if two objects are sorted as equal by the first descriptor.
