How to put escape sequence in Objective C?

I have this small code:

NSString *size = [LabelNewContent stringByEvaluatingJavaScriptFromString:@"return     Math.max(
document.body.scrollHeight, document.documentElement.scrollHeight,
document.body.offsetHeight, document.documentElement.offsetHeight,
document.body.clientHeight, document.documentElement.clientHeight
);"];

the problem is xcode doesnt recognize the parentheses and commas as a whole string.

Replace you code by 

NSString *size = [LabelNewContent stringByEvaluatingJavaScriptFromString:@"return %f",Math.max(
                      document.body.scrollHeight, document.documentElement.scrollHeight,
                      document.body.offsetHeight, document.documentElement.offsetHeight,
                      document.body.clientHeight, document.documentElement.clientHeight
                      )];

hope it will help you.

Use \ to make it multi line string

NSString *size = [LabelNewContent stringByEvaluatingJavaScriptFromString:@"return     Math.max(\
document.body.scrollHeight, document.documentElement.scrollHeight,\
document.body.offsetHeight, document.documentElement.offsetHeight,\
document.body.clientHeight, document.documentElement.clientHeight\
);"];
