展平一个 NSArray [英] Flatten an NSArray

问题描述

我有一个这样的数组:

array: (
    (
        "http://aaa/product/8_1371121323.png",
        "http://aaa/product/14_1371123271.png"
    ),
    (
        "http://aaa/product/9_1371121377.png"
    )
)

我必须像这样从那个数组创建另一个数组

and I have to create another array from that one like this

array: (
    "http://aaa/product/8_1371121323.png",
    "http://aaa/product/14_1371123271.png",
    "http://aaa/product/9_1371121377.png"
)

我该怎么做?是否可以组合所有对象并使用一些字符串将它们分开?

How can I do that? Is it possible to combine all the objects and separate them using some string?

推荐答案

示例代码:

NSMutableArray *mainArray = [[NSMutableArray alloc] init];
for (int i = 0; i < bigArray.count ; i++)
{
     [mainArray addObjectsFromArray:[bigArray objectAtIndex:i]];
}
NSLog(@"mainArray :: %@",mainArray);
