in ios alertview i have %20 symbol how to remove this..
this is my code
NSString *titile = result;
alertView = [[UIAlertView alloc]initWithTitle:title message:notifiText delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil, nil];
Since you're likely retrieving your alert text from the web or from a JSON/XML response, the string is coming in encoded with "percent escapes". You need to remove them before displaying your alert.
And lucky for you, NSString has a handy method named
stringByReplacingPercentEscapesUsingEncoding (I've linked Apple's documentation).
