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];

}
