IOS webview中cookie的讀取與保存－b

 Cookie 的讀取

 將它放在 webViewDidFinishLoad 開始后執行

 

 

 

1. NSArray *nCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];NSHTTPCookie *cookie;
2. for (id c in nCookies)
3. {
4. if ([c isKindOfClass:[NSHTTPCookie class]]){
5. cookie=(NSHTTPCookie *)c;
6. NSLog(@"%@: %@", cookie.name, cookie.value);}
7. }

 

 

2 存儲長效數據

 

我要讀取 COOKIE,為了將 COOKIE 保存下來,在下次進入 APP 的時候,再取出來使用,我寫的

 

下面兩個方法,可以存取 NSMutableDictionary 類型的數據,這種類型的數據,可以理解為鍵值對,而且可以很方便的通過下面兩行代碼讀取和修改一個健的值

 

 

1. 讀取
2. NSString *cookieValue = [cookieData valueForKey:cookieName];
3. 設置 / 增加
4. NSMutableDictionary *jsonCookie = [[NSMutableDictionary alloc] init];[jsonCookie setValue:cookieValue forKey:cookieName];
5. // 保存數據到本地
6. - (BOOL) SetLocalData:(NSString *)dataFile dataObject:(NSMutableDictionary *)dataObject{
7. // 設置路徑,並保存
8. NSString *savePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
9. NSString *saveFile = [savePath stringByAppendingPathComponent:dataFile];[NSKeyedArchiver archiveRootObject:dataObject toFile:saveFile];
10. return YES;
11. }
12. // 讀取本地保存的數據
13. - (NSMutableDictionary *) GetLocalData:(NSString *)dataFile {
14. // 按文件名來讀取數據
15. NSString *savePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
16. NSString *saveFile = [savePath stringByAppendingPathComponent:dataFile];return [NSKeyedUnarchiver unarchiveObjectWithFile: saveFile];
17. }
