TableViewCell의 evey UIWebView ActivityIndicator

Question

모든 셀에 웹 뷰가 포함 된 tableview가 있습니다. 모든 셀에 활동 지표를 추가하고 싶습니다. 따라서 웹 뷰가 완료되지 않으면 해당 셀의 특정 활동 표시기가 중단되어야합니다. 물론 내 코드에서 webview delegate는 activityIndicator를 알지 못합니다. 어떻게해야합니까? 고마워.

일부 코드 :

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil]; 

CGRect screenBound = [[UIScreen mainScreen] bounds]; 
CGSize screenSize = screenBound.size; 
CGFloat screenWidth = screenSize.width; 
CGFloat screenHeight = screenSize.height; 

if (cell == nil) { 
    NSLog(@"creating a new cell"); 

    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil]autorelease]; 

[tableView setRowHeight:screenHeight-15]; 



UIWebView *webview=[[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, screenWidth,screenHeight-95)]autorelease];  

webview.delegate = self; 

NSURLRequest *nsrequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]]; 

[webview loadRequest:nsrequest]; 

[self.view addSubview:webview]; 

[cell.contentView addSubview:webview]; 

    UIActivityIndicatorView *activityIndicator = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]autorelease]; 
    activityIndicator.center = CGPointMake(screenWidth/2, (screenHeight/2)-50); 

    [activityIndicator startAnimating]; 

    [cell.contentView addSubview:activityIndicator]; 

} 

return cell; 
}

- (void)webViewDidFinishLoad:(UIWebView *)webView 
{ 

    [activityIndicator stopAnimating]; 
}

이보십시오.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

{ 있는 UITableViewCell * 셀 =있는 tableView dequeueReusableCellWithIdentifier : 닐];

CGRect screenBound = [[UIScreen mainScreen] bounds]; 
CGSize screenSize = screenBound.size; 
CGFloat screenWidth = screenSize.width; 
CGFloat screenHeight = screenSize.height; 

if (cell == nil) { 
    NSLog(@"creating a new cell"); 

    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil]autorelease]; 

    [tableView setRowHeight:screenHeight-15]; 

    UIWebView *webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, screenWidth,screenHeight-95)]; 

    webview.delegate = self; 
    [webview setTag:indexPath.row]; 
    NSURLRequest *nsrequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]]; 

    [webview loadRequest:nsrequest]; 
    UIActivityIndicatorView *activityIndicator = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]autorelease]; 
    activityIndicator.center = CGPointMake(webview.frame.size.width/2, (webview.frame.size.height/2)-50); 
    [activityIndicator setTag:500]; 
    [activityIndicator startAnimating]; 

    [webview addSubview:activityIndicator]; 

    [cell.contentView addSubview:webview]; 


} 

return cell; 

} - (무효) webViewDidFinishLoad : (UIWebView에서 *)

기본적으로, 가장 좋은 방법은이 CustomTableCell에 의해 달성하는 것입니다.

한편이 코드를 시도 :

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil]; 

CGRect screenBound = [[UIScreen mainScreen] bounds]; 
CGSize screenSize = screenBound.size; 
CGFloat screenWidth = screenSize.width; 
CGFloat screenHeight = screenSize.height; 

if (cell == nil) { 
    NSLog(@"creating a new cell"); 

    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil]autorelease]; 

    [tableView setRowHeight:screenHeight-15]; 

    UIWebView *webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, screenWidth,screenHeight-95)];  

webview.delegate = self; 

NSURLRequest *nsrequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]]; 

[webview loadRequest:nsrequest]; 

[cell.contentView addSubview:webview]; 

    UIActivityIndicatorView *activityIndicator = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]autorelease]; 
    activityIndicator.center = CGPointMake(screenWidth/2, (screenHeight/2)-50); 

    [activityIndicator startAnimating]; 

    [cell.contentView addSubview:activityIndicator]; 

} 

return cell; 
}
