Swift添加Icon＆amp;用于滑动单元格操作的文本

Question

我尝试向Swipe Action添加图标，但我找不到任何解决方案。有人说＆＃34;使用＆traffingSwipeActionsConfigurationForRowAt＆＃39;无法实现＆＃39; trailingSwipeActionsConfigurationForRowAt＆＃39; ＆＃34 ;.这是真的还是有任何解决方案？谢谢你的回复。

Answer 1

尝试这样

func tableView(_ tableView: UITableView,
                       trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
{
      let deleteAction = UIContextualAction(style: .normal, title:  "", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
                // Your Call Here
                success(true)
      })
      deleteAction.image = UIImage(named: "Trash")
      deleteAction.backgroundColor = COLOR_ORANGE

      return UISwipeActionsConfiguration(actions: [deleteAction])
}

在此代码中，您可以添加有助于您的自定义逻辑。这适用于ios 11.

- (UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath {
    UIContextualAction *delete = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleDestructive
                                                                         title:@"DELETE"
                                                                       handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
                                                                           NSLog(@"index path of delete: %@", indexPath);
                                                                           completionHandler(YES);
                                                                       }];

    UIContextualAction *rename = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal
                                                                         title:@"RENAME"
                                                                       handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
                                                                           NSLog(@"index path of rename: %@", indexPath);
                                                                           completionHandler(YES);
                                                                       }];

    UISwipeActionsConfiguration *swipeActionConfig = [UISwipeActionsConfiguration configurationWithActions:@[rename, delete]];
    swipeActionConfig.performsFirstActionWithFullSwipe = NO;

    return swipeActionConfig;
}

我希望这会对你有所帮助
