Example CODE : NSArray, NSMutableArray, NSMutableDictionary

Array is a type of data that is in the index.

NSArray

NSArray *ArrSingle = [[NSArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"5",nil];    

NSLog(@"Show Array Single: %@",ArrSingle);

OUTPUT :

Show Array Single: (

    1,

    2,

    3,

    4,

    5

)

NSArray *ArrDimension;

ArrDimension = [[NSArray alloc] initWithObjects:

            [[NSArray alloc] initWithObjects: @"1.1", @"1.2", @"1.3", @"1.4", @"1.5", nil],

            [[NSArray alloc] initWithObjects: @"2.1", @"2.2", @"2.3", @"2.4", @"2.5", nil],nil ];

    

    

NSLog(@"Show data Array Dimension: %@",ArrDimension);

OUTPUT:

Show data Array Dimension: (

        (

        "1.1",

        "1.2",

        "1.3",

        "1.4",

        "1.5"

    ),

        (

        "2.1",

        "2.2",

        "2.3",

        "2.4",

        "2.5"

    )

)

NSLog(@"Show data Array Dimension base on index: %@",ArrDimension[1]);

  OR

NSLog(@"Show data Array Dimension base on index: %@",[ArrDimension objectAtIndex:1]);

OUTPUT:

Show data Array Dimension base on index: (

    "2.1",

    "2.2",

    "2.3",

    "2.4",

    "2.5"

)

NSMutableArray

NSMutableArray *myColors = [[NSMutableArray alloc] init];

Set array null

NSMutableArray *myColors = [NSMutableArray arrayWithObjects:  nil];

    

Inserts a given object at the end of the array :

[myColors addObject: @“blue”];

[myColors addObject: @“black”];

[myColors addObject: @“yellow”];

then green in index 0 and  yellow  in index 2

  

NSLog(@"Show data Array: %@",myColors);

OUTPUT:

Show Array color: (

    blue,

    black,

    yellow

)

NSLog(@"Show data Array at index 1: %@",myColors[2]);

OUTPUT:

Show data Array at index 1: yellow

NSArray *arrSecond = [NSArray arrayWithObjects:@"One",@"Two",@"Three",nil];

NSMutableArray *arrData = [NSMutableArray arrayWithObjects:@"Four",@"Five",@"Six",nil];

Marge two array

[arrData addObjectsFromArray:arrSecond];

NSLog(@"Show Array arrData marge arrSecond: %@",arrData);

OUTPUT:

Show Array arrData marge arrSecond: (

    Four,

    Five,

    Six,

    One,

    Two,

    Three

)

add 1 object to arrData

[arrData addObject:@"seven"];

NSLog(@"Show Array arrData after add object: %@",arrData);

OUTPUT:

Show Array arrData after add object: (

    Four,

    Five,

    Six,

    One,

    Two,

    Three,

    seven

)

NSMutableDictionary

NSMutableDictionary *myDictionary = [[ NSMutableDictionary alloc]  init];

    

[ myDictionary setObject:@"Luter" forKey:@"name"];

[ myDictionary setObject:@"IOS Developer" forKey:@"position"];

[ myDictionary setObject:@"08/12/1984" forKey:@"born"];

    

    

NSLog(@"Show Array myDictionary: %@",myDictionary);

OUTPUT:

Show Array myDictionary: {

    born = "08/12/1984";

    name = Luter;

    position = "IOS Developer";

}

NSArray *arrNS = [NSArray arrayWithObjects:@"objective c",@"PHP",@"JavaScript",nil];

NSMutableArray *arrMutable = [NSMutableArray arrayWithObjects:@"swimming”,@“footbal",@"badminton",nil];

    

Set object NSArray and NSMutableArray to NSMutableDictionary

[ myDictionary setObject:arrNS forKey:@"skill"];

[ myDictionary setObject:arrMutable forKey:@"skill"];

NSLog(@"Show Array myDictionary SET object: %@",myDictionary);

OUTPUT:

Show Array arrData after add object: {

    born = "08/12/1984";

name = Luter;

    position = "IOS Developer";

    hobby =     (

        swimming,

        footbal,

        badminton

    );

    skill =     (

        "objective c",

        PHP,

        JavaScript

    );
