보통 UIWebView 에서 특정 URL로 이동할 때 아래와 같은 코드를 사용한다.

NSURLRequest를 이용한 URL 이동

UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.frame];
NSURL *url = [NSURL URLWithString:@"https://www.hooni.net"];

NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];

[webView setBackgroundColor:[UIColor clearColor]];
[self.view addSubview:webView];

쿠키(Cookie)와 같은 헤더에 값을 실어서 보낼 때는 Request에 값을 세팅해야 하므로,

아래 코드와 같이 NSMutableURLRequest를 사용한다.

UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.frame];
NSURL *url = [NSURL URLWithString:@"https://www.hooni.net"];

NSMutableURLRequest *mutableRequest =
    [NSMutableURLRequest requestWithURL:url];

NSLog(@"%@", @"PersisteWebCookie");
NSMutableString *cookieStringToSet = [[NSMutableString alloc] init];

[cookieStringToSet appendFormat:@"ENC=%@;", @"6EA4E3F7E03A9..."];

if (cookieStringToSet.length) {
    [mutableRequest setValue:cookieStringToSet
        forHTTPHeaderField:@"Cookie"];

    NSLog(@"Cookie : %@", cookieStringToSet);
}
NSLog(@"%@", @"PersisteWebCookie Restored");

[webView loadRequest:mutableRequest];

[webView setBackgroundColor:[UIColor clearColor]];
[self.view addSubview:webView];

기존에 저장된 쿠키를 읽어오는 코드와 섞으면 아래처럼 활용할 수 있다.

UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.frame];
NSURL *url = [NSURL URLWithString:@"https://www.hooni.net"];
NSMutableURLRequest *mutableRequest =
    [NSMutableURLRequest requestWithURL:url];

NSLog(@"%@", @"PersisteWebCookie");
NSData *cookiesdata = [[NSUserDefaults standardUserDefaults]
    objectForKey:@"MySavedCookies"];

if([cookiesdata length]) {
    NSArray *cookies =
        [NSKeyedUnarchiver unarchiveObjectWithData:cookiesdata];

    for (cookie in cookies) {
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
        NSLog(@"cookiesdata ; %@", cookie);
    }
    
    NSMutableString *cookieStringToSet = [[NSMutableString alloc] init];
    for (NSHTTPCookie *cookie in cookies) {
        [cookieStringToSet appendFormat:@"%@=%@;",
            cookie.name, cookie.value];
    }
    
    if (cookieStringToSet.length) {
        [mutableRequest setValue:cookieStringToSet
            forHTTPHeaderField:@"Cookie"];

        NSLog(@"Cookie : %@", cookieStringToSet);
    }
}
NSLog(@"%@", @"PersisteWebCookie Restored");
    
[webView loadRequest:mutableRequest];

[webView setBackgroundColor:[UIColor clearColor]];
[self.view addSubview:webView];
