objective-c - iOS 单元格标签链接

Question

大家好，我是 iOS 编程的新手，我需要一些帮助。

我有一个 TableView 单元格，它由 .plist 文件中的数据填充。我需要能够在其中一个单元格内建立链接。我怎么能这样做？

这是将数据加载到单元格中的代码:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"CustomTableCell";
    static NSString *CellNib = @"DetailViewCell";



    DetailViewCell *cell = (DetailViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellNib owner:self options:nil];
        cell = (DetailViewCell *)[nib objectAtIndex:0];
    }   

    cell.accessoryType = UITableViewCellAccessoryNone;
    cell.cellTitleLabel.textColor = [UIColor blackColor];
    cell.cellTitleLabel.font = [UIFont systemFontOfSize:20.0];
    cell.cellSubtitleLabel.textColor = [UIColor darkGrayColor];

    informations = [[NSArray alloc] initWithObjects:@"City", @"Country", @"State", @"History", @"Link", nil];
    subtitles = [[NSArray alloc] initWithObjects:titleString, subtitleString, stateString, populationString, @"Link", nil];


    cell.cellTitleLabel.text = [informations objectAtIndex:indexPath.row];
    cell.cellSubtitleLabel.text = [subtitles objectAtIndex:indexPath.row];

    return (DetailViewCell *) cell; 
}

对于单元格“链接”，我需要它打开一个存储在 .plist 文件中的 url。我该怎么做？

非常感谢

首先，将以下内容移动到viewDidLoad

   informations = [[NSArray alloc] initWithObjects:@"City", @"Country", @"State", @"History", @"Link", nil];
    subtitles = [[NSArray alloc] initWithObjects:titleString, subtitleString, stateString, populationString, @"Link", nil];

其次，对于值为@"Link"的单元格

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
    DetailViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if(cell.cellTitleLabel.text == @"Link")
    {
          //Open in safari
          [[UIApplication sharedApplication] openURL:[NSURL URLWithString:cell.cellSubtitleLabel.text]];
    }
}
