How to add percent sign to NSString

Trying to create some string output using the % symbol with no luck:

[NSString stringWithFormat:@"%@% off entire order.",self.discountPercentage.text]

Example output would hopefully be something like: 25% off entire order.

Instead I get some crazy output: 25377777777776ff entire order.

Is there an escape character I need to use before the %?

Use %% to represent the % characters. (See String Programming Guide: String Format Specifiers)

The code for percent sign in NSString format is %%.This is also true for NSLog() and printf() formats.
