由于选中状态没有在返回cell的数据源方法中和数据绑定在一起，所以选中后滚动出视图再滚回来就没有选中了
1.@property (nonatomic, readonly, strong, nullable) UIImageView *imageView NS_AVAILABLE_IOS(3_0);
2.
3.@property (nonatomic, readonly, strong, nullable) UILabel *textLabel NS_AVAILABLE_IOS(3_0);

11.@property (nonatomic) UITableViewCellAccessoryType editingAccessoryType;
12.
13.@property (nonatomic, strong, nullable) UIView *editingAccessoryView;
14.
15.@property (nonatomic) UITableViewCellSelectionStyle selectionStyle;
2.accessoryType是一个结构体常量有如下几种类型及其对应对样式：
| UITableViewCellAccessoryType | 样式 |
|---|---|
| UITableViewCellAccessoryNone |  |
| UITableViewCellAccessoryDisclosureIndicator |  |
| UITableViewCellAccessoryDetailDisclosureButton |  |
| UITableViewCellAccessoryCheckmark |  |
| UITableViewCellAccessoryDetailButton |  |
3.accessoryView即为cell右侧的视图，如果accessoryView != nil，那么设置accessoryType将没有作用
1. UIButton *btn = [UIButton buttonWithType:UIButtonTypeSystem];
2. btn.frame = CGRectMake(0, 0, 80, 30);
3. [btn setTitle:@"download" forState:UIControlStateNormal];
4. cell.accessoryView = btn;
4.编辑模式,需要将tableview的editing 设置为 yes或者[tableView setEditing:YES animated:YES]; 才能进行编辑。
编辑模式下，用户可以进行删除、多选、重排序等操作。要进行多选操作必须将tableView.allowsMultipleSelectionDuringEditing = YES;在进行删除或重排序的时候必须对数据进行操作后才更新视图。
