根據webviews內容調整UITableViewCell與WebViews

我試圖根據webview的高度有一個單元格的自定義高度。根據webviews內容調整UITableViewCell與WebViews

現在我嘗試將webview的frame.size.height添加到一個NSMutableArray，當然它在insertObject上崩潰（我在這裏試過的解決方案很sl））。

我該如何做到這一點？

int indexPathIntValue; 

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    static NSString *MyIdentifer = @"PictureCell"; 

    InspirationFeedCell *cell; 
    cell = (InspirationFeedCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifer]; 
    NSBundle *mainBundle = [NSBundle mainBundle]; 
    if (cell == nil) { 
     [mainBundle loadNibNamed:@"PictureCell" owner:self options:nil]; 
     cell = self.feedCell; 
     self.feedCell = nil; 
    } 

    indexPathIntValue = indexPath.row; 

    //Here I deleted some code that fetches descriptionWebString 

    [cell.feedWebView setDelegate:self]; 
    [cell.feedWebView loadHTMLString:descriptionWebString baseURL:nil]; 

    return cell; 

} 

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

    CGRect frame = webView.frame; 
    frame.size.height = 1; 
    webView.frame = frame; 
    CGSize fittingSize = [webView sizeThatFits:CGSizeZero]; 
    frame.size = fittingSize; 
    webView.frame = frame; 

    int heightOfWebViewInt = frame.size.height; 
    [sizeOfWebViewCell insertObject:[NSNumber numberWithInt:heightOfWebViewInt] atIndex:indexPathIntTest]; 
    DLog(@"numberSizeInValue: %d", heightOfWebViewInt); 

    if (!alreadyUpdated) { 
     alreadyUpdated = YES; 
     [inspirationFeedTable reloadData]; 
    } 
} 


- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { 
    if (indexPath.row < [sizeOfWebViewCell count] && [sizeOfWebViewCell count] != 0) { 

     NSNumber *numberValueOfHeight = [sizeOfWebViewCell objectAtIndex:indexPath.row]; 


     int rowAtHeight = numberValueOfHeight.integerValue; 

     return rowAtHeight; 

    } 
    return 360; 

}
