NSArray add objects from other array - ios

Question

I have three NSArray objects. I need to add all objects for this array to NSArray that is called allMyObjects.
Have NSArray standard solution to make it for example via initialization method or do I need make custom method to retrieve all objects from other arrays and put all retrieved objects to my allMyObjects array?

Answer 1

Don't know if this counts as a sufficiently simple solution to your problem, but this is the straight forward way to do it (as alluded to by other answerers, too):
NSMutableArray *allMyObjects = [NSMutableArray arrayWithArray: array1];
[allMyObjects addObjectsFromArray: array2];
[allMyObjects addObjectsFromArray: array3];

Answer 2

once see this one ,
NSArray *newArray=[[NSArray alloc]initWithObjects:#"hi",#"how",#"are",#"you",nil];
NSArray *newArray1=[[NSArray alloc]initWithObjects:#"hello",nil];
NSArray *newArray2=[[NSArray alloc]initWithObjects:newArray,newArray1,nil];
NSString *str=[newArray2 componentsJoinedByString:#","];
NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:#"()\n "];
str = [[str componentsSeparatedByCharactersInSet:doNotWant] componentsJoinedByString: #""];
NSArray *resultArray=[str componentsSeparatedByString:#","];
NSLog(#"%#",resultArray);
O/P:-
(
hi,
how,
are,
you,
hello
)

Answer 3

You can call addObjectsFromArray: method on your allMyObjects array.

Answer 4

Here am adding code for store and get datas from array to array.
To store array to array
NSMutableArray rowOneRoundData = [NSMutableArray arrayWithObjects: #"45",#"29",#"12",nil];
NSMutableArray rowTwoRoundData = [NSMutableArray arrayWithObjects: #"41",#"45",#"45",nil];
NSMutableArray rowThreeRoundData = [NSMutableArray arrayWithObjects: #"12",#"45",#"22",nil];
NSMutableArray rowFourRoundData = [NSMutableArray arrayWithObjects: #"45",#"12",#"61",nil];
NSMutableArray rowFiveRoundData = [NSMutableArray arrayWithObjects: #"12",#"14",#"14",nil];
NSMutableArray rowSixRoundData = [NSMutableArray arrayWithObjects: #"12",#"12",#"12",nil];
NSMutableArray rowSevenRoundData = [NSMutableArray arrayWithObjects: #"12",#"36",#"83",nil];
NSMutableArray rowEightRoundData = [NSMutableArray arrayWithObjects: #"37",#"57",#"45",nil];
NSMutableArray rowNineRoundData = [NSMutableArray arrayWithObjects: #"12",#"93",#"83",nil];
NSMutableArray rowTenRoundData = [NSMutableArray arrayWithObjects: #"16",#"16",#"16",nil];
NSArray circleArray = [[NSArray alloc]initWithObjects:rowOneRoundData,rowTwoRoundData,rowThreeRoundData,rowFourRoundData,rowFiveRoundData,rowSixRoundData,rowSevenRoundData,rowEightRoundData,rowNineRoundData,rowTenRoundData, nil];
Get data from Circle Array
for (int i= 0; i<10;i++)
{
NSArray *retriveArrar = [[circleArray objectAtIndex:i] mutableCopy];
}
