addObjects to my Model (NSObject Class) NSMutableDictionary

Question

I stuck somewhere. I want to create NSMutableDictionary in my Model Class which name is Data.h & .m and i want to some add some object from my controller. I tried some Methots but i couldnt do it ..

there is my model .m file

#import "Data.h"
//Dictiniory and Array Definitions...

NSMutableArray *plist;
NSMutableDictionary *kartlarDict;
@implementation Data

+(void)load{
    plist = [[NSMutableArray alloc] initWithObjects:@"Garanti", nil];
}

+(NSMutableArray *)getPlistArray {
    return plist;
}

//set Methots for kartlarDict...
-(id)initWithBankaAdi:(NSString *)aBankaAdi KartAdi:(NSString *)aKartAdi{`

        bankaFK = @"BankaAdi";
         kartFK  = @"KartAdi";

        bankaAdi = aBankaAdi;
        kartAdi  = aKartAdi;

        NSMutableDictionary *tmpKartlarDict = [[NSMutableDictionary alloc]     initWithObjectsAndKeys:
                                           bankaAdi,bankaFK,
                                           kartAdi,kartFK, nil];

         [kartlarDict addEntriesFromDictionary:tmpKartlarDict];

        return self;
}

//get Methots for kartlarDict...
+(NSMutableDictionary *)getKartlarDict{
    return kartlarDict;
}

@end

there is my .m CONTROLLER file.

- (void)viewDidLoad
{
    [super viewDidLoad];

    [Data getKartlarDict];
    [Data getPlistArray];
     NSLog(@"%@",[Data getKartlarDict]);

     Data *p1 = [[Data alloc] initWithBankaAdi:@"HSBC" KartAdi:@"Advantage Kart"];

     kartlarListe = [[NSMutableArray alloc] initWithObjects:[Data getKartlarDict], nil];
}

I only want to create some NSMutableDict or Array and i want to set them from my controller file and of course i want to get them back to all other controller file.

How can i do this ? Please help !

Note : I'am newbie now but i always sleep 5 hour for these days coz i want to learn this language a.s.a.p. I watched too many youtube videos, and apple resource..

It's unclear what you're doing or what your main question is. It appears that you never create your kartlarDict object. But you also express a desire to pass values between objects, and that's a whole separate discussion -- very simple if you understand object-oriented principles, but very difficult if you don't. — Hot Licks, Mar 06 '14 at 21:40

In your init method kartlarDict is not initialized:

-(id)initWithBankaAdi:(NSString *)aBankaAdi KartAdi:(NSString *)aKartAdi{`
    bankaFK = @"BankaAdi";
    kartFK  = @"KartAdi";
    bankaAdi = aBankaAdi;
    kartAdi  = aKartAdi;

    NSMutableDictionary *tmpKartlarDict = [[NSMutableDictionary alloc]     initWithObjectsAndKeys:
                                       bankaAdi,bankaFK,
                                       kartAdi,kartFK, nil];

    [kartlarDict addEntriesFromDictionary:tmpKartlarDict];

// kartlarDict is nil here!!!!!!!!!!!!!!
    return self;
}

change

[kartlarDict addEntriesFromDictionary:tmpKartlarDict];

to

kartlarDict = [NSMutableDictionary dictionaryWithDictionary:tmpKartlarDict]

or even

kartlarDict = [tmpKartlarDict mutableCopy]; // it will be enought

Try this, and I have explained:

    -(id)initWithBankaAdi:(NSString *)aBankaAdi KartAdi:(NSString *)aKartAdi{
        if(self = [self init]){ //First of all, you should call super init or self basic init method 
           //following code will be more clear.
           NSMutableDictionary *tmpKartlarDict = [[NSMutableDictionary alloc]     initWithObjectsAndKeys:
                                               aBankaAdi,@"BankaAdi",
                                               aKartAdi, @"KartAdi", nil];

           if(!kartlarDict){ //Maybe kartlarDict init in the above basic init method, if not, ignore the judgement.
               kartlarDict = [NSMutableDictionary dictionaryWithDictionary:tmpKartlarDict]
           }
           else{
              [kartlarDict addEntriesFromDictionary:tmpKartlarDict];

           }
        }
        return self;
    }
