使用 NIB 定义 UITableViewCell Out of Storyboard

Question

我使用 Json 数组来显示来自服务器的数据。

当我将 CellIdentifier 更改为

我在 CellIdentifier 中使用的 @Cell 时，pushDetailView 正在工作并且它会转到下一页，但是当我再次更改为 CustomCell 时，只需在第一页显示城市和州的名称，当我单击它时不会转到下一页。 我需要@CustomCell的原因，因为我在第一页需要 2 个标签视图，当我将其更改为@cell它时显示一个标签。

谢谢。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"CustomCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
// Configure the cell...
City * cityObject;
cityObject = [ citiesArry objectAtIndex:indexPath.row];
cell.textLabel.text = cityObject.cityState;
cell.detailTextLabel.text = cityObject.cityPopulation;

cell.detailTextLabel.numberOfLines = 4;

//NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://mobileapps.binaryappdev.com/applelogo.png"]  ];
//[[cell imageView] setImage:[UIImage imageWithData:imageData]  ];

return cell;
}

如果你在推入单元格时没有自定义单元格的segue，你的方法didSelectRow：AtIndexPath将被调用。你可以从该方法或[self performSegueWithIdentifier： @"pushDetailView" sender： self];
