Hi Mark,
So I have a dictionary like so:
NSDictionary * countries = [NSDictionary dictionaryWithObjects:[NSArray
arrayWithObjects:@"Australia",@"Canada",@"United Kingdom",@"United States",nil]
forKeys:[NSArray arrayWithObjects:@"au",@"ca",@"uk",@"us",nil]];
I want to present them alphabetically as menuItems in an NSPopUpButton. I grab
the list of keys:
NSMutableArray * sortkeys = [NSMutableArray arrayWithArray:[countries
allKeys]];
What I have come up with is this:
[sortkeys sortUsingComparator:^NSComparisonResult(id obj1, id obj2) {
return [(NSString*)obj1 compare:(NSString*)obj2 ];
} ];
Is this a sane approach ? Seems a bit fussy to have to spec the cast like this.
Or is this just the what-is of this kind of functionality?
