iOS TableView loads data very slowly
ios, ios5, ios6, iphone
Solution
It seems you're not calling `[self.tableView reloadData];` from the main thread and that could be the cause of your problem.
You could try:
[self.tableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:YES];

Problem
I'm working on a project that parse data from web service and shows in a table view. Everything is ok, but I'm not satisfied with the performance of tableview. After parsing data form web I called reload data to show the data, But it is not showing cells immediately. It shows the data after 10/15 seconds later. I've checked all data's are loaded before I called reload data. And the strange thing is that it shows the cells immediately if I try to drag the table. Any idea? Update ``` -(void)receivedCategories:(NSMutableArray *)categoryItems{ [self.spinner stopAnimating]; self.categories=categoryItems; if (self.tableView!=nil) { [self.tableView reloadData]; } } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.categories count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CategoryCell"; CategoryCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier]; cell.category = [self.categories objectAtIndex:indexPath.row]; return cell; } ``` CategoryCell.m ``` @implementation CategoryCell - (void)setCategory:(Category *)category { [self.categoryTitle setText:category.title ]; [self.categorySubTitle setText:category.description]; } @end ```
