Initializing NSStrings with Large, constant html strings_问答_开发者

I have a large constant html string which I'd like to display on my UIWebView. For some reason, when I try to use the constant string ( with @"LARGE_STRING" ) I get some weird errors, saying I have an unexcpected '@' at the start, that I miss terminating ' " ' characters, that I use undeclared expressions and etc. the thing is - I do escape the string, atleast the ' " ' in it.

What am I missing in here?

Tnx!

Edit: Example:

NSString *myString = [NSString stringWithString:@"&lt;title&gt;&#x05d1;&#x05e1;&#x05d9;&#x05e1;&#x05d9; HTML &#x05dc;&#x05d9;&#x05de;&#x05d5;&#x05d3;&lt;/title&gt; &lt;META http-equiv=&quot;Content-Type&quot;

If you have " characters in the string, then you must escape them:

    NSString *myString = @"This string contains \"quotes\". If they are not \"escaped\", that will cause errors".

Or, another possibility, you are using #defines like

#define LARGE_STRING "This is an extremely large string (well, OK, not so large)"

Then you should do

#define LARGE_STRING @"This is an extremely large string (well, OK, not so large)"

and

    NSString *myString = LARGE_STRING;

Edit

Hmmm... your example looks fine. It should compile, if it really contains the HTML-style " codes and not hard-coded " characters. Just make sure your string (it is really long indeed) is not wrapped with hard linefeeds.

I just tried, and your example compiles fine, in Objective-C (Xcode 4.1). Note that if you try to pass such a string to a C function, it should be converted to a valid C string first.
