UITableView 轻松自定义多选cell 不使用系统样式

1、先看效果

UITableView.gif

2、需要什么效果

1.点击全选需要全选cell

2.在全选状态下，取消任意一个，全选按钮为 normal 转态

3.一个一个选择，直到全部选择，全选按钮为 selected 状态

3、实现

3.1.在cell中添加一个 按钮 或者 图片，用来显示选择或者未选择中的转态，在初始化时 默认设为 未选择的转态或者图片,和透明度为0或hidden = YES ,我使用的是按钮做这个状态的现实，只需要UIControlStateNormal和UIControlStateSelected状态下的图片，不需要实现点击事件

RSButton* selectedButton = [[RSButtonalloc]initWithType:RSButtonTypeOnlyImage];

selectedButton.alpha=0.0;

[selectedButtonsetImage:[UIImage imageNamed:@"rs_common_selected_normal_2"] forState:UIControlStateNormal];

[selectedButtonsetImage:[UIImage imageNamed:@"rs_common_selected_selected_2"] forState:UIControlStateSelected];

[viewaddSubview:selectedButton];

self.selectedButton= selectedButton;


3.2.重写UITableViewCell的方法


- (void)setSelected:(BOOL)selectedanimated:(BOOL)animated {

    [supersetSelected:selectedanimated:animated];

    self.selectedButton.selected= selected;

}


以上代码就可以实现 cell 在点击的时候，改变按钮的图片显示

4、设置UITableView

4.1.设置UITableView 是否可以多选


        _tableView.allowsMultipleSelection = YES;


4.2.点击 编辑 让 UITableView 进入多选状态（编辑状态）让按钮从隐藏状态显示出来

    4.2.1 重写UITableViewCell 的方法，显示或隐藏按钮，在UITableView 进入编辑状态的时候会调用

    -(void)setEditing:(BOOL)editing animated:(BOOL)animated {    

        // [super setEditing:editing animated:animated]; 这里不要调用super 不然显示是系统自带的样式

        [UIView animateWithDuration:0.2

                         animations:^{

               self.selectedButton.alpha= editing ?1.0:0.0;

        }];

   }


    4.2.2 点击 编辑的时候 让UITableView 进入编辑转态

    /// 编辑按钮点击事件

    - (void)editAction:(UIButton*)sender {

        sender.selected= !sender.selected;

        [self.tableView setEditing:sender.selected animated:YES]; // 这个就会调用 2.1 中的代码 显示或隐藏 cell中的 按钮

    }


    4.2.3 设置 UITableViewDelegate 中的代码,

    - (void)tableView:(UITableView*)tableViewdidSelectRowAtIndexPath:(NSIndexPath*)indexPath {

            if(tableView.isEditing) {// 判断一下是不是编辑状态

            [tableViewselectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionNone];

            self.selectedIndexPaths = tableView.indexPathsForSelectedRows; // 获取 UITableView 当前选中的 cell

        }else{    

        }

    }

    - (void)tableView:(UITableView*)tableViewdidDeselectRowAtIndexPath:(NSIndexPath*)indexPath{

            if(tableView.isEditing) { // 判断一下是不是编辑状态

            [tableViewdeselectRowAtIndexPath:indexPathanimated:YES];

            self.selectedIndexPaths = tableView.indexPathsForSelectedRows; // 获取 UITableView 当前选中的 cell

        }

    }

    4.2.4 必须设置 不然在 UITableView 在编辑状态下 无法响应 4.2.3 中的代码

    - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{

        return UITableViewCellEditingStyleDelete | UITableViewCellEditingStyleInsert;

    }

5、设置记录 选择的 数组

5.1 添加属性

@interfaceRSFamilyListController()

@property (strong,  nonatomic) UITableView * tableView;

@property (weak,    nonatomic) RSView * editView;

@property (weak,    nonatomic) RSButton * checkAllButton; // 全选按钮 它在  editView上 点击编辑的时候隐藏或显示

@property (strong,  nonatomic) NSArray * datas; /// 源数据

@property (strong,  nonatomic) NSArray * selectedIndexPaths; /// 记录选择中的 cell 4.2.3 和 4.2.4 中的代码有

@end


5.2 重写 selectedIndexPaths set方法，用来判断是不是 全全部选中



- (void)setSelectedIndexPaths:(NSArray *)selectedIndexPaths {

    _selectedIndexPaths = selectedIndexPaths;

    // 判断一下 选择的数量是不是等于源数据的数量,这就可以 显示 按钮的 UIControlStateNormal 状态 或者 UIControlStateNormal 状态

    self.checkAllButton.selected = (selectedIndexPaths.count == self.datas.count);

}
