Question

When i try to call a NSMutableArray from a diffirent class its empty why?

CLASS A

.h
@interface Dashboard : UIViewController {
    NSMutableArray *tablearrayCREDITS;

}
@property(nonatomic,retain)NSMutableArray *tablearrayCREDITS;

.m
@synthesize tablearrayCREDITS;

And im filling it with data from a JSON array.This all works as it should be..

CLASS B

.h
    #import "Dashboard.h"

    @interface CreditsAndDebits : UIViewController {


    //nothing needed here..

}

.m

@implementation CreditsAndDebits
@synthesize selectedIndexPath;
    NSMutableArray *thearray;

- (void)viewDidLoad {
    Dashboard *db = [[Dashboard alloc]init];
    thearray = db.tablearrayCREDITS;
}

//When i debug it and set a breakpoint on where i allocate the Dashboard.. the tablearrayCREDITS says objects 0??, i dont get it? why is it going empty when im calling it?

Answer 1

- (void)viewDidLoad {

    Dashboard *db = [[Dashboard alloc]initWithNibName:@"Dashboard" bundle:nil...........];


    db.tablearrayCREDITS=[[NSMutableArray alloc]init];

    [db.tablearrayCREDITS addObject:@"madhu"];

    thearray = db.tablearrayCREDITS;


//here nslog them
}

//you have to create Dashboard object not mutable array
