Adding two arrays together

开发者_C百科

I call two feeds that both return an NSMutableArray, I then need to make the two arrays into one.

NSMutableArray *array1 = [JSONWrapper downloadFeed];
NSMutableArray *array2 = [JSONWrapper downloadFeed];

// something like: array1 += array2

---

Use -addObjectsFromArray::

[array1 addObjectsFromArray:array2];

---

NSArray *newArray = [array1 arrayByAddingObjectsFromArray:array2];
