IOS7 table index displays as a white bar

Question

I am trying to set up a table index, but it appears as a white panel on the right. I use a storyboard. Does anyone know what is going on? Thanks

The code:

#pragma mark - Tableview datasource - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections in a tableview return self.arrayOfCharacters.count; } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { // Return the height of each cell return 55; } - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { // Return table index return [NSArray arrayWithArray: [@"A|B|C|D|E|F|G|H|I|J|K|L|M|N|O|P|Q|R|S|T|U|V|W|X|Y|Z|#" componentsSeparatedByString:@"|"]]; } - (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index { // Match the section titls with the sections NSInteger count = 0; // Loop through the array of characters for (NSString *character in self.arrayOfCharacters) { if ([character isEqualToString:title]) { return count; } count ++; } return 0; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the each section return [[self.objectsForCharacters objectForKey:[self.arrayOfCharacters objectAtIndex:section]] count]; } - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { // Return the title for each section return [NSString stringWithFormat:@"%@", [self.arrayOfCharacters objectAtIndex:section]]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellIdentifier = @"preplanCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; } // Create a pointer to our preplan LBPrePlan *preplan = [[self.objectsForCharacters objectForKey:[self.arrayOfCharacters objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row]; cell.textLabel.text = preplan.name; cell.detailTextLabel.text = preplan.address; return cell; }

Found my problem. With iOS7, you have the option to set sectionIndexBackgroundColor. It turns out he worked all the time.

Answer 2

You can change the background color of the indexview index in ios7 using the following code

  [[UITableView appearance] setSectionIndexBackgroundColor:[UIColor clearColor]]; [[UITableView appearance] setSectionIndexTrackingBackgroundColor:[UIColor lightGrayColor]]; [[UITableView appearance] setSectionIndexColor:[UIColor darkGrayColor]];
