Question

I have a problem with sorting… I need to sort NSArray containing NSDictionaries. As an order key I have to use element from the NSDictionary.

I was reading a little about sorting NSArray but it is not clear to me.
Could you try help me?

Answer 1

Use an NSSortDescriptor and a keypath. Assuming the key for the dictionary is key:

NSSortDescriptor *sd = [NSSortDescriptor sortDescriptorWithKey:@"key" ascending:YES];
NSArray *sorted = [array sortedArrayUsingDescriptors:[NSArray arrayWithObject:sd]];
