保存cookies？

Question

我想知道如何在Xcode中保存cookie。我想使用我從一個網頁獲得的cookie並使用它來訪問另一個網頁。我使用下面的代碼登錄到網站，並且我想保存從此連接獲得的cookie以在我建立另一個連接時使用它。

NSString *post = [NSString stringWithFormat: @"some data", _username, _password ]; 
// NSLog(@"%@",post); 
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; 

NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]]; 

NSURL *url=[NSURL URLWithString:@"url"]; 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
[request setURL:url]; 
[request setHTTPMethod:@"POST"]; 
[request setValue:postLength forHTTPHeaderField:@"Content-Length"]; 
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 
[request setHTTPBody:postData]; 

NSData *urlData; 
NSHTTPURLResponse *response; 
NSError *error; 
urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; 

更新：感謝到iOS開發我能得到的cookie。下面的代碼是一個for循環來nslog所有的cookie名稱，域，值。幫助查看您當前存儲的所有Cookie。

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]; 
for (int i = 0; i < [cookies count]; i++) { 
    NSHTTPCookie *cookie = [cookies objectAtIndex:i]; 
    NSLog(@"Cookie Name: %@", [cookie name]); 
    NSLog(@"Cookie Domain: %@", [cookie domain]); 
    NSLog(@"Cookie Value: %@", [cookie value]); 
}

當您收到回覆時，更新後的cookie將在NSHttpCookieStorage單一噸中可用。

您可以通過

NSArray *cookies = [[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]
