how to combining two static array

Question

I want to combine two Static Arrays into another Static Array. My two static arrays are dailyPortfolioPrices1 & dailyPortfolio2.

- (NSArray *)dailyPortfolioPrices1  //my first array
{
    static NSArray *prices = nil;
    if (!prices)
    {
        prices = [NSArray arrayWithObjects:
                  [NSDecimalNumber numberWithFloat:582.13],
                  [NSDecimalNumber numberWithFloat:604.43],
                  [NSDecimalNumber numberWithFloat:32.01],
                  nil];
    }
    return prices;

- (NSArray *)dailyPortfolioPrices2 //my second array
{
    static NSArray *prices2 = nil;
    if (!prices2)
    {
        prices2 = [NSArray arrayWithObjects:
                  [NSDecimalNumber numberWithFloat:476.13],
                  [NSDecimalNumber numberWithFloat:534.43],
                  [NSDecimalNumber numberWithFloat:32.01],
                  nil];
    }
    return prices2;
}

Can anyone tell me how to combine these two Arrays into an another array named dailyPortfolioPrices. And I need to display dailyPortfolioPrices using an index.

Thanks for help in advance

Your requirement is not clear, in which language/script you are trying to combine two static arrays? — I Bajwa PHD

Does this thread ask a similar question? Also, I would check here as well. — Vandal

I agree with @IBajwa - what language is this? I also stumbled on this thread that seemed similar. — Vandal

You cannot combine those arrays as they are in different scopes. Make them instance variables so any code in the class can access them. — l00phole

NSArray *dailyPortfolioPrices=[[self dailyPortfolioPrices1] arrayByAddingObjectsFromArray:[self dailyPortfolioPrices2]];

I think this would help you:

NSArray *dailyPortfolioPrices=[[self dailyPortfolioPrices1] arrayByAddingObjectsFromArray:[self dailyPortfolioPrices2]];

The arrays can be concatenated into a new array using

NSArray *dailyPortfolioPrices = [self.dailyPortfolioPrices1 arrayByAddingObjectsFromArray:self.dailyPortfolioPrices2];

The values in the array can be retrieved along with their index using

for (NSInteger i = 0; i < dailyPortfolioPrices.count; i++) {
    NSLog(@"index %ld, item %@", (long)i, [newArray objectAtIndex:i]);
}

where I have added an NSLog to output the values to the console.

Those arrays are local and cannot be accessed from outside the method.

The arrays are passed as return values from their respective functions. They are not being accessed from inside the method.

Yeah that's certainly true.
