Person *p1=[Person alloc]init];
p1.Name=@“Anil”;
p1.City=@“Uttarpradesh”;
p1.Country=@“India”;

Person *p2=[Person alloc]init];
p2.Name=@“Rakesh”;

NSArray*UnSortedArray=[NSArray arrayWithObjects:p1,p2,p3, nil];

   NSArray *sortedArray=nil;
   Bool isUseCaseInsensitiveCompare=false;
    @try

    NSMutableArray * descriptors= [NSMutableArray arrayWithObject:valueDescriptor];
    sortedArray =[UnSortedArray sortedArrayUsingDescriptors:descriptors ];
