Question

I want to create function to return a 1d array with 2 elements in it something like below :

(NSArray *) myFunction {
 NSArray * myArr = [[NSArray alloc]initwithobjects:[NSNumbers numberwithfloat:1.0f],[NSNumbers numberwithfloat:1.0f]];
//the above line is just pseudo code 

}

but when I want to retrieve nsarray form this function i want to do it at the simplest way
which it seems impossible in objective-c
this is what I’ve written to get two simple float value which is not appropariate but i don’t have any further knowledge of how to doing it in simpler way

NSArray *tt2 = [[NSArray alloc] initWithArray:[self myFunction]];
 float fp1=0.0f;
    float fp2=0.0f;
    BOOL firstTime = YES;
    for(NSNumber *n in tt2)
    {
        if (firstTime) {
            NSLog(@"%@" , n);
            fp1 = [n floatValue];
            firstTime = NO;
        }
        else {
            fp2 = [n floatValue];
        }

    }

above code is ridiculos but i don’t have any other choice unless you advice me how can I convert a nsarray to nsnumber then a nsnumber to float[]

Answer 1

If you’re only storing floats, you could just use a C array instead. NSArray can only store objects.

However, it looks like you haven’t heard of the objectAtIndex method?

NSNumber *firstNumber = [myArray objectAtIndex:0];
NSNumber *secondNumber = [myArray objectAtIndex:1];

Does that help with your situation, it isn’t really clear what you’re trying to do from the question.
