为什么披露指标不显示?
Why disclosure indicator don't show?
当应用程序 运行 在模拟器中 Disclosure indicator 没有 show.Because 这个我不能去 Detail

我怎样才能做到这一点?请帮助我。我是新人
试试这个
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
.......
}
更新
