    <p>I have a scrollview with a dynamic height. The height depends on the image and the text that I got back from my core database. I have the following.</p> <p>In my <code>ViewDidLoad</code> I call my method <code>getNewsItem</code>.</p> <p>Here is how the method looks like.</p> <pre><code>-(void)getNewsItem{ NSManagedObjectContext *context = [RKManagedObjectStore defaultStore].persistentStoreManagedObjectContext; NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:@"News"]; NSLog(@"news ID IN METHOD %d",_newsId); NSPredicate *predicate = [NSPredicate predicateWithFormat: @"new_id = %d",_newsId]; [fetchRequest setPredicate:predicate]; NSSortDescriptor *descriptor = [NSSortDescriptor sortDescriptorWithKey:@"new_id" ascending:YES]; fetchRequest.sortDescriptors = @[descriptor]; NSArray *matches = [context executeFetchRequest:fetchRequest error:nil]; newsItem = [matches objectAtIndex:0]; lblTitle.text = newsItem.pnt_new_title; lblTitle.font = [UIFont fontWithName:@"ShadowsIntoLightTwo-Regular" size:16.0]; lblTitle.textColor = [UIColor whiteColor]; NSString *datetext = [newsItem.new_date substringWithRange:NSMakeRange(0, 11)]; lblDate.text = datetext; lblDate.font = [UIFont fontWithName:@"TitilliumWeb-Regular" size:15.0]; NSString *imgUrl = @""; imgUrl = [NSString stringWithFormat:@"http://mosaqua.appmax.be/%@",newsItem.new_imgurlbig]; NSData *imgData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:imgUrl]]; UIImage *image = [UIImage imageWithData:imgData]; self.img_Picture.image = [UIImage imageWithData:imgData]; float ratioImage = image.size.width/image.size.height; float ratioPlaceholder = 320/206; float width; float heigth; float x; if(ratioImage &lt; ratioPlaceholder){ width = 206 * ratioImage; heigth = 206; }else{ width = 320; heigth = 320/ratioImage; } if (heigth &lt; self.view.bounds.size.width){ x = (self.view.bounds.size.width - width) / 2; }else{ x = 0; } NSLog(@"x is %f",x); if(heigth &lt; 206){ self.img_titlback.frame= CGRectMake(-4, heigth-8, self.view.bounds.size.width+5, 45); self.lblTitle.frame = CGRectMake(40, heigth-8, self.view.bounds.size.width, 40); self.btnBack.frame = CGRectMake(5, heigth, 67, 28); self.lblDate.frame = CGRectMake(7, heigth+30, self.view.bounds.size.width, 45); [self updateScrollView:newsItem.pnt_new_description andHeight:heigth+60]; }else{ [self updateScrollView:newsItem.pnt_new_description andHeight:300]; } self.img_Picture.frame = CGRectMake(x, 0, width, heigth); } </code></pre> <p>Webview method</p> <pre><code>-(void)updateScrollView:(NSString *)text andHeight:(float)height{ NSLog(@"till here in scrollview"); UIWebView *webView = [[UIWebView alloc]initWithFrame:CGRectMake(10, height,self.view.bounds.size.width-30, 20)]; [[webView scrollView] setBounces: NO]; webView.delegate = self; [scrollView addSubview:webView]; [self setWebDescription:webView]; } </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
