相当于Java Vector的Objective-C？

Question

在Objective-C中，Java的Vector相当于什么？

Answer 1

尝试使用NSMutableArray。

Answer 2

The closest thing you will find is NSMutableArray, execpt that contrary to java Vector, it is not thread safe. If you do not need thread safety, NSMutableArray is nice. I suspect that if you use java vector instead of List, it is that you need thread safaty, then in objective-C, you should probably use NSArray. THe API is slightly different, since the add operation of an element to a NSArray returns a new array instance, but it is thread safe, see http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/Multithreading/ThreadSafetySummary/ThreadSafetySummary.html
