I have a short list with "Name" and "Surname" fields.
I want to sort this list by "Surname".
How should I build the NSArray?
How should I use the NSArray methods?
At this point it is important to know how your Array is build.
The best would be if you use your own Data-Class. And there
you just need to implement one or two funcions like this one:
- (NSComparisonResult)compareByName:(myData *)other
{
return [[self name] compare: [other name]];
}
And then you sort the Array using this function:
myArray = [myArray sortedArrayUsingSelector: @selector(compareByName:)];
The idea of this is, to send a comare Message to every object in your
Array and then sort it by the results.
E.g. if your Array has just NSString objects you can use this function:
myArray = [myArray sortedArrayUsingSelector: @selector(compare:)];
understand? HTH
cheers
