问题描述
可可的新手，似乎缺少了一些东西.
New to Cocoa, and seem to be missing something.
将NSArray的前x个元素用作另一个NSArray的最优雅/惯用的方法是什么?显然，我可以遍历它们并手动存储它们，但是似乎必须有一种更标准的方法来执行此操作.
What is the most elegant/idiomatic way to obtain the first x elements of an NSArray as another NSArray? Obviously I can iterate through them and store them manually, but it seems like there has to be a more standard method of doing this.
我期望有一个-arrayWithObjectsInRange:或类似的东西，但是什么也看不到...
I was expecting there to be an -arrayWithObjectsInRange: or something similar, but don't see anything...
NSArray* largeArray...// Contains 50 items...
NSArray* smallArray = // fill in the blank
// smallArray contains first 10 items from largeArray
谢谢！
推荐答案
您可以使用 subarrayWithRange: .
You can use subarrayWithRange:.
NSArray *smallArray = [largeArray subarrayWithRange:NSMakeRange(0, 10)];
