Objective-c：包含空格的字符串长度
我正在尝试获取字符串中包括空格的字符数。 如果我有一个字符串说：“你好，你好吗？” 我运行这段代码：
NSUInteger newLength = [myString length];
它返回 15。 但是当你包含空格时有 18 个字符......那么我应该使用什么代码？或者我是否必须运行代码来用星号等字符替换所有空格，计算字符数，然后将字符串设置回原始字符串。这不会太糟糕，除非我必须多次这样做，所以我正在寻找一种更快的方法。谢谢！
I am trying to get the number of characters in a string including spaces.
If I have a string saying: "hello how are you?"
and I run this code:
NSUInteger newLength = [myString length];
it returns 15.
There are 18 characters though when you include spaces... so what code should I use? Or am I going to have to run code to replace all of the spaces with some character like an asterix, count the number of characters and then set the string back to it's original string. That wouldn't be too bad except I have to do this numerous times so I'm looking for a quicker way. Thanks!

你能发布你的字符串创建代码吗？我觉得很奇怪。但 NSString length doc 确实说：
无论如何，您可以获取 c 字符串并使用 strlen，也许这会有所帮助。
Could you post your string creation code? It seems strange to me. But NSString length doc does say:
In any case, you could get the c string and use strlen, maybe that would help.
来自文档..
返回接收器中的 Unicode 字符数。
空格也是一个unicode字符From the Documentation..
Returns the number of Unicode characters in the receiver.
Spaceis also a unicode character你用它来获取字符串的长度，包括空格：（
也就是说，你不应该返回15，而是18）
You use this to get the length of the string, including spaces:
(that is, you should not be returned 15, but 18)
