Question

In NSMutableArray or NSArray how do you set up the row structure. All the examples I can find just deal with one dimensional integers or strings.

So how do you go about setting up an array row structure like:

Integer, String, Date

Answer 1

You can make custom class and add collection of these objects in an array.

For example please assume that we have to do some rows about places then create a class PLACE.h

@interface PLACE : NSObject 
{
   NSString *title;
   NSString *summary;
   NSString *url;
   NSString *latitude;
   NSString *longitude;
}

@property   (nonatomic, retain) NSString    *title;
@property   (nonatomic, retain) NSString    *summary;
@property   (nonatomic, retain) NSString    *url;
@property   (nonatomic, retain) NSString    *latitude;
@property   (nonatomic, retain) NSString    *longitude;

@end

PLACE.m

@implementation PLACE

@synthesize title;
@synthesize summary;
@synthesize url;
@synthesize latitude;
@synthesize longitude;


- (void) dealloc
{
  [title release];
  [summary release];
  [url release];
  [latitude release];
  [longitude release];
  [super dealloc];
}
@end

Create instance of the class PLACE for each place and hold the objects in the array. I think that solves your problem.
