webview中cookie的读取与保存

应该做到更好 Cookie 的读取这里就简单写段代码了,它很容易懂,你应该将它放在 webViewDidFinishLoad 开始后执行

NSArray *nCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];NSHTTPCookie *cookie;
for (id c in nCookies)
{

if ([c isKindOfClass:[NSHTTPCookie class]]){

cookie=(NSHTTPCookie *)c;

NSLog(@"%@: %@", cookie.name, cookie.value);}

}

应该做到更好 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

读取

NSString *cookieValue = [cookieData valueForKey:cookieName];

设置 / 增加
NSMutableDictionary *jsonCookie = [[NSMutableDictionary alloc] init];[jsonCookie setValue:cookieValue forKey:cookieName];

// 保存数据到本地
- (BOOL) SetLocalData:(NSString *)dataFile dataObject:(NSMutableDictionary *)dataObject{

// 设置路径,并保存

NSString *savePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];

NSString *saveFile = [savePath stringByAppendingPathComponent:dataFile];[NSKeyedArchiver archiveRootObject:dataObject toFile:saveFile];
return YES;

}

// 读取本地保存的数据
- (NSMutableDictionary *) GetLocalData:(NSString *)dataFile {

// 按文件名来读取数据

NSString *savePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];

NSString *saveFile = [savePath stringByAppendingPathComponent:dataFile];return [NSKeyedUnarchiver unarchiveObjectWithFile: saveFile];

}
