Byte array in objective-c
提问by Raju
How can I create a byte array in Objective-C?
如何在 Objective-C 中创建字节数组？
I have some data like this:0x12, 0x23, 0x34, 0x45, 0x56, 0x67, 0x78, 0x89, 0x12, 0x23, 0x34, 0x45, 0x56, 0x67, 0x78, 0x89, that I want to prepare as a byte array.
我有一些这样的数据：0x12, 0x23, 0x34, 0x45, 0x56, 0x67, 0x78, 0x89, 0x12, 0x23, 0x34, 0x45, 0x56, 0x67, 0x78, 0x89，我想准备一个字节数组。

You can simply use plain C syntax, which is available in Objective-C:
您可以简单地使用 Objective-C 中提供的普通 C 语法：
const char myByteArray[] = {
0x12,0x23,0x34,0x45,
0x56,0x67,0x78,0x89,
0x12,0x23,0x34,0x45,
0x56,0x67,0x78,0x89 };

Either use the plain C solution given by mouviciel or read the class description of NSDataand NSMutableData.
要么使用 mouviciel 给出的普通 C 解决方案，要么阅读NSDataand的类描述NSMutableData。
