IOS webview中cookie的读取与保存－b

Cookie 的读取

将它放在 webViewDidFinishLoad 开始后执行

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 存储长效数据

我要读取 COOKIE,为了将 COOKIE 保存下来,在下次进入 APP 的时候,再取出来使用,我写的

下面两个方法,可以存取 NSMutableDictionary 类型的数据,这种类型的数据,可以理解为键值对,而且可以很方便的通过下面两行代码读取和修改一个健的值

1. 读取
2. NSString *cookieValue = [cookieData valueForKey:cookieName];
3. 设置 / 增加
4. NSMutableDictionary *jsonCookie = [[NSMutableDictionary alloc] init];[jsonCookie setValue:cookieValue forKey:cookieName];
5. // 保存数据到本地
6. - (BOOL) SetLocalData:(NSString *)dataFile dataObject:(NSMutableDictionary *)dataObject{
7. // 设置路径,并保存
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. // 读取本地保存的数据
13. - (NSMutableDictionary *) GetLocalData:(NSString *)dataFile {
14. // 按文件名来读取数据
15. NSString *savePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
16. NSString *saveFile = [savePath stringByAppendingPathComponent:dataFile];return [NSKeyedUnarchiver unarchiveObjectWithFile: saveFile];
17. }
