表格多选删除

1、系统方式

  • 将要删除的数据添加到待删数组中，从数据源中删除待删数组中包含的数据，刷新表格。
  • OC 中可设置编辑模式为 UITableViewCellEditingStyleDelete | UITableViewCellEditingStyleInsert; 或者设置 myTableView.allowsMultipleSelectionDuringEditing = YES; 进入多选模式。

  • 1.1 待删数据数组初始化

// 声明待删数据数组
@property(nonatomic, retain)NSMutableArray *tempDeleteArray;

// 初始化待删数据数组
tempDeleteArray = [[NSMutableArray alloc] init];

  • 1.2 自定义方法

// 编辑按钮点击响应事件
- (void)editClick:(UIButton *)button {

	// 改变编辑开关状态
	[myTableView setEditing:!myTableView.editing animated:YES];

	// 设置编辑模式，允许编辑时多选，或者在协议方法中设置
	myTableView.allowsMultipleSelectionDuringEditing = YES;

	// 当编辑状态发生改变的时候，清空待删数组
	[tempDeleteArray removeAllObjects];

	[myTableView reloadData];
}

// 删除按钮点击响应事件
- (void)deleteClick:(UIButton *)button {

	// 从数据源中删除待选数组中包含的数据
	[myDataArray removeObjectsInArray:tempDeleteArray];

	// 清空待删数组
	[tempDeleteArray removeAllObjects];

	[myTableView reloadData];
}

  • 1.3 UITableView 协议方法

// 设置编辑模式
/*
删除、插入、多选删除，不设置默认时为删除，
或者在编辑按钮点击事件中直接设置 myTableView.allowsMultipleSelectionDuringEditing = YES;
*/
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {

	// 多选删除
	return UITableViewCellEditingStyleDelete | UITableViewCellEditingStyleInsert;                       
}

// 表格选中点击响应事件
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

	// 判断 tableView 的编辑状态，表格处于编辑状态
	if (tableView.isEditing) {
		// 选中 cell 的时候，将对应的数据源模型添加到待删除数组中
		[tempDeleteArray addObject:[myDataArray objectAtIndex:indexPath.row]];
	}
	else {
		// 恢复未选中状态时的颜色
		[tableView deselectRowAtIndexPath:indexPath animated:YES];
	}
}

// 表格取消选中点击响应事件
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {

	// 判断 tableView 的编辑状态，表格处于编辑状态
	if (tableView.isEditing) {
		// 将对应的数据模型从待删除数组中移除
		[tempDeleteArray removeObject:[myDataArray objectAtIndex:indexPath.row]];
	}
}
