NSArray add objects from other array

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?

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];
}

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
)

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];

You can call addObjectsFromArray: method on your allMyObjects array.
