How to save fetched iCloud data objects into a single Array?

This is all my objects and i want to save all objects into single array.

**dataArray:**

<__NSArrayI 0x15e1a460>(
<__NSArrayM 0x15e244a0>(

I am using this loop for to get all objects and save into single Array:

for (int i = 0 ; i < dataArray.count; i++){
    for (int j = 0 ; j<[[dataArray objectAtIndex:i] count]; j++) {
       total addObject:[dataArray objectAtIndex:j]];
    }
}

Using C-style iteration is not absolutely necessary, here's what you could do:

for(id object in dataArray) {
    for(id subobject in object) {
        [mutableArray addObject:subobject];
    }
}
