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

IMHO, easiest way to sort such array is

[arr sortedArrayUsingDescriptors:@[[NSSortDescriptor sortDescriptorWithKey:@"self.intValue" ascending:YES]]]

If your array contains float values, just change key to self.floatValue or self.doubleValue
