我正在尝试设置表索引,但它在右侧显示为白条。我正在使用故事板。有谁知道发生了什么?谢谢
代码:
#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;
}
