我有一个存储NSMutableArray的NSMutableArray。如何向数组添加数组?

5 个解决方案

#1

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.

或连接数组。

[myArray addObjectsFromArray:otherArray];

Both of which are documented in the documentation.

这两个文档都在文档中记录。

#2

Since an array is just an object like any other:

因为数组和其他数组一样只是一个对象:

[myContainerMutableArray addObject:someOtherArray];

Or if you want to concatenate them:

或者如果你想把它们连接起来:

[myFirstMutableArray addObjectsFromArray:otherArray];

#3

You add it like any other object.

就像添加其他对象一样。

NSMutableArray *innerArray = [NSMutableArray array];
NSMutableArray *outerArray = [NSMutableArray array];
[outerArray addObject:innerArray];

#4

[YourArray addObjectsFromArray:OtherArray];

[YourArray addObjectsFromArray OtherArray):;

#5

In case if you add the same NSMutableArray Object, Like

如果你添加了相同的NSMutableArray对象，比如。

NSMutableArray *mutableArray1 = [[NSMutableArray alloc]initWithObjects:@"test1",@"test2",@"test3",nil];

NSMutableArray *mutableArray2 = [[NSMutableArray alloc]initWithObjects:@"test4",@"test5",@"test6", nil];

mutableArray1 = [NSMutableArray arrayWithArray:mutableArray1];

[mutableArray1 addObjectsFromArray:mutableArray2]; 

Nslog(@"mutableArray1 : %@",mutableArray1);
