Answer 1

in cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
....
UIView *customView = [[UIView alloc]init];
customView.tag = 100;
....
return cell;
}
and in
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
UIView *customView = [cell.contentView viewWithTag:100];
for (id view in customView.subViews) {
if ([view isKindOfClass:[UIWebView class]]) {
UIWebView *menuWeb = (UIWebView *)view;
}
}
}
hope this will help

Answer 2

There are a couple of ways you can achieve this.
The simplest way would be to assign a tag to the webview and then retreive it when the cell is tapped.
When you create the cell add:
[menuWeb setTag:SOME_CONSTANT_NUMBER];
Then inside the webview delegate's didSelectRowAtIndexPath method retrieve the cell and it's webView:
UITableViewCell *cell = [tableVoew cellForRowAtIndexPath:indexPath];
UIWebView *webView = [cell viewWithTag:SOME_CONSTANT_NUMBER];

Answer 3

Try this one, in cellForRowAtIndexPath tag CustomView and webview so that you can retrieve using tag-
......
customView.tag = 111;
......
webView.tag = 222;
.......
Then in didSelectRowAtIndexPath
UITableViewCell *cell = (UITableViewCell *) [tableView cellForRowAtIndexPath:indexPath];
UIView *customView = [cell.contentView viewWithTag:111];
Use viewWithTag to find out webview
UIWebView *wView = [customView viewWithTag:222];
Or iterate over custom view to find out webview
UIWebView *wView = nil;
for ((id) subView in [customView subviews]) {
if ([subView isKindOfClass:[UIWebView class]]){
//Found WebView
wView =(UIWebView *) subView;
break;
}
}
