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);
}
