% sign in string objective c

Question

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

Answer 1

Try %%.

Short answer, short question. :)

Answer 2

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

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%%";
