NSString @"\" adding backslash character objective-c

Question

Does anyone know of an easy way to add a single backslash "\" to a NSString in Objective-C? I am trying to have a NSString *temp = @"\/Date(100034234)\/";

I am able to get a double backslash or no backslash, but unable to get a single backslash. Any help would be appreciated. Thanks

Answer 1

The string @"\\" is a single backslash, @"\\\\" is a double backslash

Answer 2

This is a bug in NSLog. I found a mailing list archive with a message dated in 2002 of someone that filed a bug for this here. The person also said this:

Nothing has been done as far as I can tell. I don't understand how they've done it, but the escaping does work for the string, just not for NSLog.

So I guess you will have to come up with your own implementation of a log message if you really want backslashes.

Answer 3

The strings and NSLog are working fine for me (iPhone SDK 3.1.2 and Xcode 3.2.1):

NSLog(@"\\"); // output is one backslash
NSLog(@"\\\\"); // output is two backslashes
NSLog(@"\\/Date(100034234)\\/"); // output is \/Date(100034234)\/
