url의 normal을 bigger나 mini로 바꾸어주면 이미지를 얻을수 있다.

bigger : 73 x 73

normal : 48 x48

mini : 24 x 24

사용하려는 클래스의 .m파일 끝에 붙이면 됨.

    NSArray *cells = self.tableView.visibleCells;

    for(UITableViewCell *cell in cells){

        cell.userInteractionEnabled = NO;

    }

*** 이렇게 하면 보이는 셀만 잠근다.

스크롤 하면 재사용해서 셀을 돌리기 때문에 꼬인다.

셀을 생성하는 구문도 수정필요.

NSObject에 <UIWebViewDelegate>선언하고

웹뷰의 델레게이트에 연결해도 안먹길래..

뭔가 수상해서.

UIViewController에 <UIWebViewDelegate> 선언하고,

거기에 델레게이트 연결하니까 먹더라.

... 델레게이트 구현하는 곳이 뷰컨트롤러여야되나?...

NSURLRequest initWithURL:cachePolicy:timeoutInterval

cachePolicy: NSURLCacheStorageNotAllowed

하거나

[[NSURLCache sharedURLCache] removeCachedResponseForRequest:targetRequest];

하면 된다고 하는데?
