I am sorting an NSMutableArray
as follows:
NSSortDescriptor *sortDescriptor;
sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:str_key ascending:bool_asc_desc] autorelease];
NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor];
NSArray *sortedArray;
sortedArray = [ads_printers_array sortedArrayUsingDescriptors:sortDescriptors];
The problem is that this is case sensitive, and I would like to make it case insensitive. How can I do that? I tried reading the docs and found something like this:
sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:str_key ascending:bool_asc_desc selector: @selector(caseInsensitiveCompare)] autorelease];
However, I have no idea what I should be putting in the selector argument. Thanks!
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:str_key
ascending:YES selector:@selector(caseInsensitiveCompare:)];
ads_printers_array = [ads_printers_array sortedArrayUsingDescriptors:[NSArray
arrayWithObject:sortDescriptor]];
