In my application i have following fields:

testMsg.fromEmail = @"[e-mail]";
testMsg.toEmail = @"%@",email;
testMsg.relayHost = @"smtp.gdsadfds.co.uk";
testMsg.requiresAuth = YES;
testMsg.login = @"[e-mail]";
testMsg.pass = @"ngdfadfdadfa";
testMsg.subject = @"The Money Shop Order Confirmation";
testMsg.wantsSecure = YES; // smtp.gmail.com doesn't work without TLS!

In testMsg.toEmail=@”some email”; i want to pass string from textField.text=email;

How can i do that

Answer 1

- (BOOL)validateEmailWithString:(NSString*)email{
    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}"; 
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex]; 
    return [emailTest evaluateWithObject:email];

}

if([self validateEmailWithString:textField.text){
    textMsg.toEmail = textField.text;
}else{
      NSLog(@"Email was not valid");
}

According to your comment

- (NSMutableArray*)validateEmailWithString:(NSString*)emails {

    NSString *emailRegx = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";

    NSMutableArray *validEmails = [[NSMutableArray alloc] init];
    NSArray *emailList = [emails componentsSeparatedByString:@","];

    for (NSString *_email in emailList){

         NSPredicate *emailChecker = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex]; 
         if ([emailChecker evaluateWithObject:_email])
              [validEmails addObject:_email];
    }
    return [validEmails autorelease];
}
