开发项目时候需要用到tableview左滑删除,就研究了一下,话不多说直接上代码
//设Cell可编辑
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
//设置删除按钮
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
return UITableViewCellEditingStyleDelete;
}
//进入编辑(删除)模式
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
//出现alterView隐藏删除按钮
[tableView setEditing:NO animated:YES];
if (editingStyle == UITableViewCellEditingStyleDelete) {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:@"你确定删除该消息?" preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil]];
[alertController addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {
//需要先删除数据源中对应数据,不然执行下一步会崩溃
[reconnaissanceListArr removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}]];
[self presentViewController:alertController animated:YES completion:nil];
}
}
//修改编辑按钮文字
-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath
{
return @"删除";
}
//设置进入编辑状态时,Cell不会缩进
- (BOOL)tableView: (UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath
{
return NO;
}
