％符号字符串目标c

Question

我想知道我如何在NSString中做一个％符号，我试过\\%和\\\\%

Answer 1

Try %% .

Short question, short answer. :)

Answer 2

只需将%%放在目标c中使用％符号。

Answer 3

There's no special escaping required for percent signs. Just write:

str = @"Rate of Return (in %)";

...unless you mean NSString stringWithFormat . But your question doesn't say so.

Answer 4

According to Apple's 'String Format Specifiers' page, simply use %% .

For example:

NSString * aString = @"50%%";
