UIActivityIndicator in Custom UITableViewCell

I have a custom UITableViewCell like this:

// Custom.h
@interface CustomQuestionCell : UITableViewCell {

    IBOutlet UIWebView *mywebView;

}

-(void) AssignWebView:(NSString *) _text;

// Custom.m
-(void) AssignWebView:(NSString *) _text {


    [mywebView loadHTMLString:_text baseURL:nil];

}

I can successfully use the UITableViewCell in UITableView in file called MainViewController. The delegate of UITableViewCell is MainViewController. In MainViewController I am calling below code to assign value to UIWebView.

// cellForRowAtIndexPath
//CustomQuestionCel.xib uses the class Custom defined above.

CustomQuestionCell *cell = (CustomQuestionCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier];

if(cell == nil) {

    [[NSBundle mainBundle] loadNibNamed:@"CustomQuestionCellView" owner:self options:nil];
    cell = tblQuestionCell;
}

[cell AssignWebView:[ListOfQuestions object开发者_运维知识库AtIndex:indexPath.row]];

return cell;

My question is:

I would like to display an activity indicator in each cell while the UIWebView is loading the data.

How can I accomplish this?

1. In your CustomQuestionCell header (.h file):

@interface CustomQuestionCell : UITableViewCell <UIWebViewDelegate> {
   IBOutlet UIWebView *mywebView;
   IBOutlet UIActivityIndicatorView *mySpinner;
}

2. In your CustomQuestionCell implementation (.m file):

- (void) AssignWebView:(NSString *) _text {
    [myWebView setDelegate:self];
    [mywebView loadHTMLString:_text baseURL:nil];
}

- (void)webViewDidStartLoad:(UIWebView *)webView {
    [myWebView setHidden:YES];
    [mySpinner startAnimating];
}

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    [mySpinner stopAnimating];
    [myWebView setHidden:NO];
}

3. In your CustomQuestionCellView nib file insert a spinner (UIActivityIndicatorView). Connect it as an mySpinner outlet to your File's Owner. Check Hides when stopped checkbox and uncheck Animating one.
