Sorting an NSArray of NSString

Question

Can someone please show me the code for sorting an NSMutableArray? I have the following NSMutableArray:

NSMutableArray *arr = [[NSMutableArray alloc] init];
         


        

Answer 1

You should use this method:

[arr sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)];

in a NSArray or:

[arr sortUsingSelector:@selector(caseInsensitiveCompare:)];

in a "inplace" sorting NSMutableArray

The comparator should return one of this values:

• NSOrderedAscending
• NSOrderedDescending
• NSOrderedSame
