iOS table简单实现增加移动和删除功能与自定义cell的实现
在RootViewController.h文件中
#import
@interface RootViewController :UIViewController
{
BOOL editState;
}
//@property (nonatomic,retain)NSArray *noteList;
@property (nonatomic,retain)NSMutableArray *noteList;
@property (weak, nonatomic) IBOutletUITableView *mTableView;
//添加移动操作
- (void)noteMove;
//添加删除
- (void)noteDelete:(id)sender;
@end
在RootViewController.m
#import "RootViewController.h"
@interface RootViewController () <UITableViewDataSource,UITableViewDelegate>
@end

}
@end
自定义cell
xib文件
CustomCell.h文件为:
#import
@interface CustomCell : UITableViewCell
@property (weak, nonatomic) IBOutlet UILabel *dateLabel;
@property (weak, nonatomic) IBOutlet UILabel *titleLabel;
@end
RootViewController.m改为
//
// RootViewController.m
// 实现一个简单的表
