% sign in string objective c

问题

i am wondering how i do a % sign within a NSString, i have tried \% and \\%

回答1:

Try %%.

Short question, short answer. :)

回答2:

just put %% to use a % sign within objective c.

回答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.

回答4:

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

For example:

NSString * aString = @"50%%";
