How do I alphabetically sort a custom object field within a NSMutable Array?

Question

I have a custom object like:

#import 

@interface Store : NSObject{
    NSString *name;
    NSString *address;
}

@property (nonat         


        

Answer 1

NSSortDescriptor *sortDescriptor =
    [NSSortDescriptor sortDescriptorWithKey:@"name"
                                  ascending:YES
                                   selector:@selector(caseInsensitiveCompare:)];
[nameOfArray sortedArrayUsingDescriptors:@[sortDescriptor]];

Related documentation:

• [NSArray sortedArrayUsingDescriptors:]
• NSSortDescriptor

Answer 2

Regexident's answer is based on NSArrays, the corresponding in-place sorting for NSMutableArray would be -sortUsingDescriptors:

[storeArray sortUsingDescriptors:
                    [NSArray arrayWithObject:[NSSortDescriptor sortDescriptorWithKey:@"name" 
                                                                           ascending:YES 
                                                                            selector:@selector(caseInsensitiveCompare:)]]];

Now storeArray it-self will be sorted.
