Question

I want to sort alphabetically the NSMutableArray and add an object to the beginning of array.

For example :

NSMutableArray *myArray = [[NSMutableArray alloc] initWithObjects:@"Red",@"Blue",@"Green",nil];

I want in return myarray = “blue”,”green”,Red”;

and then I have to add “multicolor” option at the beginning of array.

So myarray becomes: “multicolor”,”blue”,”green”,Red”;

Or if it is possible to sort array without disturbing the “multicolor” option (which will be at the first place), this could also be acceptable.

Thanks.

Use one of the sort* methods to sort the array.

Use insertObject:atIndex: with index 0 to insert at the beginning of the array.
