UItUItableView 自定义 多选和全选
这个是StoryBoard写了
model 类
#import
@interface My_CommodityModel : NSObject
//按钮选中
@property (nonatomic,assign) BOOL seleted;
//是否改变 移动
@property (nonatomic,assign) BOOL isMoved ;
@end
My_MyCommodityTableViewCell
#
#import
@interface My_MyCommodityTableViewCell : UITableViewCell
//最左边的选中图片
@property (weak, nonatomic) IBOutlet UIImageView *selectedImageView;
//商品介绍
@property (weak, nonatomic) IBOutlet UILabel *goodNamelabel;
@property (weak, nonatomic) IBOutlet UIView *moveBackgroundView;
//商品图片
@property (weak, nonatomic) IBOutlet UIImageView *goodsImageView;
@end
@end
// 这里主要用了 一个tableViewCell 两种标识符 防止Cell重用机制
不会写博客，下面复制代码了
#import "My_FootViewController.h"
#import "My_MyCommodityTableViewCell.h"
#import "My_CommodityModel.h"
@interface My_FootViewController ()
{
BOOL isSeleted; //最上面 删除按钮 是否是选择状态
NSInteger count; // 点击cell 选中状态的个数 用来判断全选按钮的状态
}
@property (weak, nonatomic) IBOutlet UITableView *tableView;
@property (weak, nonatomic) IBOutlet UIButton *deleteButton;//导航栏删除按钮
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *tableViewBottom;//tableView下面的约束
@property (weak, nonatomic) IBOutlet UIView *bottomView;//最下面的View
//全选按钮
@property (weak, nonatomic) IBOutlet UIButton *allSeletedButton;//全选按钮
@property (nonatomic,strong)NSMutableArray *dataArray;
@end
