IOS: fill a NSMutableArray with some NSMutableArray

In my project I must fill an NSMutableArray with some NSMutable array, my code is:

This is a method

-(void) fill {
[smal开发者_StackOverflow中文版lArray removeAllObjects]; //when I call this method I delete every object inside smallArray

for {
//in this for I fill with some object a NSMutableArray that I called "smallArray"

[smallArray addObject:object];
}

//outside this for I have my NSMutable bigArray that I must fill with smallArray
[bigArray = ?????];

How can I fill this bigArray?

Unlesss I'm missing something, simply use the addObject: method (as you're already doing for the small array), supplying the smallArray to add.

i.e.: [bigArray addObject:smallArray];

If however you just want to add the objects from smallArray into the bigArray, then you could use the addObjectsFromArray: method...

[bigArray addObjectsFromArray:smallArray];

...which will append the objects after any existing ones within bigArray. For more information, check out the relevant section of the NSMutableArray Class Reference documentation.

If i understang correctly you must have an array that contains other arrays?

[bigArray addObject:smallArray];

Then you can access the array like this

NSMutableArray * arrayfromArray =[bigArray objectAtIndex: someIndex];
