iOS 实现UITableView左滑删除功能的三种方案

一、概述

UITbableView作为列表展示信息，除了展示的功能，有时会用到删除的功能，删除功能可以直接使用系统自带的删除功能，当横向向左轻扫cell时，右侧出现红色的删除按钮，点击删除当前cell。

二、效果图

三、技术实现

方案1:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    NIMRecentSession *recentSession = self.recentSessions[indexPath.row];
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        //删除数据源
    }
}

方案2:

-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewRowAction *deleteAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"删除" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {
      //删除数据源
    }];
    deleteAction.backgroundColor = [UIColor redColor];

    return @[deleteAction];
}

方案3:

API_AVAILABLE(ios(11.0))

- (UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath {
    UIContextualAction *deleteAction = [UIContextualAction contextualActionWithStyle:UIContextualActionStyleNormal title:@"删除" handler:^(UIContextualAction * _Nonnull action, __kindof UIView * _Nonnull sourceView, void (^ _Nonnull completionHandler)(BOOL)) {
      //删除数据源
    }];
    deleteAction.backgroundColor = Red6;
    
    UISwipeActionsConfiguration *Configuration = [UISwipeActionsConfiguration configurationWithActions:@[deleteAction]];
    Configuration.performsFirstActionWithFullSwipe = NO;
    return Configuration;
}
