objective c - NSString with wrong characters when using UTF-8 -

-

i data utf-8 encoded xml file, , want display every element in uitableview . want cells have same size , display 2 first text lines data possible tried remove carriage returns.

in cellforrow method changed :

[[mycell textlabel] settext:data];

by :

[[mycell textlabel] settext:[self correctdata:data]];

here correctdata method :

- (nsstring *) correctdata : (nsstring *) str {     nsmutablestring *res = [nsmutablestring stringwithformat:@""];     for(int = 0 ; < [str length] ; i++)     {         char car = [str characteratindex:i];         if(car != 10 && car != 13)             [res appendstring:[nsstring stringwithformat:@"%c",car]];     }     return res; }

and correctly removes carriage returns, alters utf-8 chars. example, bit of initial string (str) :

diplômé(e) d'etat

and function becomes :

diplÙmÈ(e) d'etat

what should ? thanks.

nsstring works unichar characters stored on 16bits whereas char 8bits long. converting unichar char alter characters code point above u+00ff.

you can solve issue replacing char unichar , %c %c.

edit: that's not efficient. may better use regular expressions replace newline characters in once:

str = [str stringbyreplacingoccurrencesofstring:@"[\r\n]+"                                      withstring:@""                                         options:nsregularexpressionsearch                                            range:nsmakerange(0, str.length)];

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
