IOS: add an object in a specific position of a NSMutableArray

Question

In my project I want to add an object in a specific position of a NSMutableArray, example:

if(index ==1) {
// I want add object at position 1 of NSMutableArray
}

if(index == 2) {
// I want add object at position 2 of NSMutableArray
}
...
if(index == 15) {
// I want add object at position 15 of NSMutableArray
}

How can I do?

Please note that index must not be greater that the count of elements in the array.

but in this way, if I add an object atindex:0 and after I add an object atIndex:3, it gives me an error because I haven't add yet abject at position 1 e 2....How can I solve?

@blackguardian - This is an assumption based on the fact that I don't see your complete code, but maybe you might want to use a dictionary instead of an array?

You could use a C array for this.

id objects[15];

objects[index] = yourObject;
