    <p>I have a <code>tableview</code> loading properly for the first time, but it should reload the data when I'm calling the method <code>loadJsonData</code>. The <code>reloadData</code> method is called at the end of the <code>loadJsonData</code> method. But the <code>tableview</code> is not reloading. The data source is updated before calling the <code>reloadData</code> method. The delegate and dataSource of <code>tableview</code> are also set to self.</p> <p>I checked if it is executing <code>numberOfRowsInSection</code> method and found that it is not executing the method. Can anybody help me?</p> <p>Below is the code:</p> <pre><code>-(void)loadJsonData:(NSString *)fileName:(int )count { titleArray=[[NSMutableArray alloc]init]; dateArray=[[NSMutableArray alloc]init]; descriptionArray=[[NSMutableArray alloc]init]; urlArray=[[NSMutableArray alloc]init]; thumbnailArray=[[NSMutableArray alloc]init]; NSString *filePath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"json"]; NSString *fileContent = [[NSString alloc] initWithContentsOfFile:filePath]; SBJSON *Parser = [[SBJSON alloc] init]; NSDictionary *data = (NSDictionary *) [Parser objectWithString:fileContent error:nil]; NSArray *items=[data objectForKey:fileName]; NSSortDescriptor *sortDescriptor; sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:@"date" ascending:YES] autorelease]; NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor]; NSArray *sortedArray; sortedArray = [items sortedArrayUsingDescriptors:sortDescriptors]; items=sortedArray; for (NSDictionary *item in items) { NSString *temp=[item objectForKey:@"title"]; NSString* str = [temp stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [titleArray addObject:str]; temp=[item objectForKey:@"date"]; [dateArray addObject:temp]; temp=[item objectForKey:@"thumbnailURL"]; str = [temp stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [thumbnailArray addObject:str]; temp=[item objectForKey:@"description"]; str = [temp stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [descriptionArray addObject:str]; temp=[item objectForKey:@"htmlURL"]; str = [temp stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [urlArray addObject:str]; } [Parser release]; if (count==1) { [tableview performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO]; NSLog(@"reload data test"); } } -(NSInteger) numberOfSectionsInTableView:(UITableView *)aTableView { // Return the number of sections. return 1; } -(NSInteger)tableView:(UITableView *)aTableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the section. NSLog(@"nof rows test.."); return [thumbnailArray count]; } </code></pre> <p>EDIT</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { CustomCell *cell; cell=(CustomCell *)[tableView dequeueReusableCellWithIdentifier:@"cell"]; if (cell == nil) { cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"cell"] autorelease]; cell.contentMode=UIViewContentModeScaleAspectFit; cell.Title.text=[titleArray objectAtIndex:indexPath.row]; cell.description.text=[descriptionArray objectAtIndex:indexPath.row]; NSURL *url = [NSURL URLWithString:[thumbnailArray objectAtIndex:indexPath.row]]; NSData *data = [NSData dataWithContentsOfURL:url]; UIImage *img = [[UIImage alloc] initWithData:data]; cell.Image.image=img; cell.Date.text=[dateArray objectAtIndex:indexPath.row]; NSLog(@"date is : %@",cell.Date.text); cell.selectionStyle=UITableViewCellSelectionStyleNone; } return cell; } </code></pre>

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).
