iOS 11下 editActionsForRowAtIndexPath被替換成兩個新的代理

Demo

// iOS 11 新特性 左邊側滑

- (nullable UISwipeActionsConfiguration *)tableView:(UITableView *)tableView leadingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath {
}

// iOS 11 新特性 右邊側滑
- (nullable UISwipeActionsConfiguration *)tableView:(UITableView *)tableView trailingSwipeActionsConfigurationForRowAtIndexPath:(NSIndexPath *)indexPath {
}

直接進行左右兩邊進行側滑操作
