回答by August Lilleaas
You can either store a reference to another array (or any type of object) in your array:
您可以在数组中存储对另一个数组（或任何类型的对象）的引用：
[myArray addObject:otherArray];
Or concatenate the arrays.
或者连接数组。
[myArray addObjectsFromArray:otherArray];
Both of which are documented in the documentation.
这两者都记录在文档中。

Since an array is just an object like any other:
由于数组只是一个像任何其他对象一样的对象：
[myContainerMutableArray addObject:someOtherArray];
Or if you want to concatenatethem:
或者，如果您想连接它们：
[myFirstMutableArray addObjectsFromArray:otherArray];

You add it like any other object.

如果您添加相同的 NSMutableArray 对象，例如

mutableArray1 = [NSMutableArray arrayWithArray:mutableArray1];
[mutableArray1 addObjectsFromArray:mutableArray2];
Nslog(@"mutableArray1 : %@",mutableArray1);
