TableView编辑

准备工作
1.Student.h

#import <Foundation/Foundation.h>@interface Student : NSObject@property(nonatomic,copy)NSString *name;@property(nonatomic,copy)NSString *phone;@property(nonatomic,copy)NSString *address;@property(nonatomic,copy)NSString *age;@property(nonatomic,copy)NSString *sex;@property(nonatomic,copy)NSString *hobby;@end

2.Student.m

#import "Student.h"@implementation Student-(void)setValue:(id)value forUndefinedKey:(NSString *)key{}@end

3.RootViewController.m

#import "RootViewController.h"#import "Student.h"@interface RootViewController ()<UITableViewDataSource,UITableViewDelegate>@property(nonatomic,retain)NSMutableArray *stuArr;@property(nonatomic,retain)UITableView *tableView;@end@implementation RootViewController- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view.    self.view.backgroundColor=[UIColor whiteColor];    [self createData];    self.tableView=[[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStylePlain];    [self.view addSubview:self.tableView];    [self.tableView release];    self.tableView.dataSource=self;    self.tableView.delegate=self;    //设置导航栏编辑按钮    self.navigationItem.rightBarButtonItem=self.editButtonItem;    //开启一下tableView的编辑模式//    [self.tableView setEditing:YES animated:YES];}//重写一下系统提供的编辑按钮(rightButton)点击方法-(void)setEditing:(BOOL)editing animated:(BOOL)animated{    [super setEditing:editing animated:animated];    [self.tableView setEditing:editing animated:animated];}-(void)createData{    NSString *path=@"/Users/dllo/Desktop/UI/UI11_tableView编辑/UI11_tableView编辑/Student.plist";    NSArray *arr=[NSArray arrayWithContentsOfFile:path];    self.stuArr=[NSMutableArray array];    for (NSDictionary *dic in arr) {        Student *stu=[[Student alloc] init];        [stu setValuesForKeysWithDictionary:dic];        [self.stuArr addObject:stu];        [stu release];    }}-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    Student *stu=self.stuArr[indexPath.row];    stu.name=@"陈伟霆";//    [self.tableView reloadData];    //单行刷新(不消耗资源)    [self.tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationRight];}-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{    return self.stuArr.count;}-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{    static NSString *reuse=@"reuse";    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:reuse];    if (!cell) {        cell=[[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:reuse] autorelease];    }    Student *stu=self.stuArr[indexPath.row];    cell.textLabel.text=stu.name;    return cell;}

二.
逐行的去设置哪些行编辑,哪些行不编辑

#pragma mark 逐行的去设置哪些行编辑,哪些行不编辑-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{//    if (indexPath.row%2==0) {//        return YES;//    }else{        return YES;//    }}

设置编辑模式

-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{    //返回的是多选状态//    return UITableViewCellEditingStyleInsert|UITableViewCellEditingStyleDelete;    return UITableViewCellEditingStyleDelete;}

设置删除按钮的标题

-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{    return @"来点我";}

实现左滑效果,而且是对应按钮功能的方法

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{    NSLog(@"编辑开始");    //判断当前编辑模式    if(editingStyle==UITableViewCellEditingStyleDelete){     //先把数组里的对象删掉        [self.stuArr removeObjectAtIndex:indexPath.row];        //第一种方式//        [self.tableView reloadData];        //第二种方式        [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationLeft];    }}

移动

-(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{    //他只是视觉上移动,并没有改变数据的顺序,所以想要改变数组顺序,需要用代码实现    //获取要移动的数据    Student *stu=[self.stuArr[sourceIndexPath.row] retain];    //在数组里把这个对象移除掉    [self.stuArr removeObjectAtIndex:sourceIndexPath.row];    [self.stuArr insertObject:stu atIndex:destinationIndexPath.row];    [stu release];}

- (nullable NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath{    UITableViewRowAction *actionFirst=[UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive  title:@"通话" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {        NSLog(@"233333333333");    }];    actionFirst.backgroundColor=[UIColor cyanColor];    return @[actionFirst];}
