App crashed while sending and receiving special character - iphone

Question

I'm creating one chatting application.but,now I'm facing one problem while sending special character "&". I'm Using php web-services for sending and receiving the messages.while sending "&" character,and after that when some one received this character,the application is crashed.

Answer 1

here replace that character with its code like bellow...
when pass it in web-service at that time replace it like bellow..
yourString = [yourString stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
and then when you want to receive it at that time replace with special character..
yourString = [yourString stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
after display it in UITextView or UITextField
UPDATE:
if (string2 != nil) {
string1 = [NSString stringWithString:string2];
NSString *strTemp = [NSString stringWithString:string2];
NSLog(#"\n\n Temp String ==>> %#",strTemp);
}
UPDATE:
NSString *yourString = #"Hello & How Are You?";
yourString = [yourString stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
NSLog(#"\n\n String Here => %#",yourString);
At sending string to web-serive use bellow strign..
NSString *yourStringForWeb = #"Hello & How Are You?";
yourStringForWeb = [yourStringForWeb stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
and pass this yourStringForWeb to the web-service...
NSString *string = #"Hello & How Are You?";
string = [string stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
string = [string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
string = [string stringByReplacingOccurrencesOfString:#"&" withString:#"%26"];
NSLog(#"\n\n ===>> Before ==>> %#",string);
NSString *string2 = string;
string2 = [string2 stringByReplacingOccurrencesOfString:#"%20" withString:#" "];
string2 = [string2 stringByReplacingOccurrencesOfString:#"%26" withString:#"&"];
NSLog(#"\n\n ===>> After ==>> %#",string2);
OutPut =>
===>> Before ==>> Hello%20%26%20How%20Are%20You?
===>> After ==>> Hello & How Are You?
