做一个tableView，包含增删改移动功能，并且修改值的时候，在按home键的时候会自动保存。如果可以的话使者保存自定义的类数组保存到plist中。
实现步骤：
1.创建一个SingleViewApplication的项目，首页命名为FirstViewController
FirstViewController.h:
#import <UIKit/UIKit.h> @interface FirstViewController : UITableViewController @property(nonatomic,retain) NSMutableArray *array; @end
FirstViewController.m:
#import "FirstViewController.h" #import "DXWViewController.h" @interface FirstViewController () @end NSString *CellIdentifier = @"Cell"; @implementation FirstViewController - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { self.array = @[ [[DXWViewController alloc] initWithStyle:UITableViewStylePlain]]; self.title = @"目录列表"; } return self; } - (void)viewDidLoad { [super viewDidLoad]; [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:CellIdentifier]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } #pragma mark - Table view data source - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.array count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; int row = [indexPath row]; cell.textLabel.text = ((DXWViewController *)self.array[row]).title; //有右边的>符号 cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { int row = [indexPath row]; [self.navigationController pushViewController:self.array[row] animated:YES]; } @end
2.创建二级子视图控制器，不带xib文件，命名DXWViewController
![]()
![]()
DXWViewController.h:
#import <UIKit/UIKit.h> @protocol change <NSObject> -(void)changeData:(int)row Name:(NSString *)name; @end @interface DXWViewController : UITableViewController<UIAlertViewDelegate> @property(nonatomic,retain)NSMutableArray *array; @property(retain,nonatomic)NSIndexPath *indexPath; @end
DXWViewController.m:
#import "DXWViewController.h" #import "EditViewController.h" BOOL RIGHTBUTTON; @interface DXWViewController () @end @implementation DXWViewController //获取沙盒文件路径 -(NSString *)getPath { //用来获得Document地址 NSArray *arr = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);//注意：这里是NSDocument不是NSDocumentation,特别注意 NSLog(@"%@",arr); //在地址上增加文件 NSString *path = [arr[0] stringByAppendingPathComponent:@"abc.plist"]; NSLog(@"%@",path); return path; } -(BOOL)writeDataToFile:(NSString *)path DataSource:(NSMutableArray *)array { return [array writeToFile:path atomically:YES]; } -(NSMutableArray *)getDataFromFile:(NSString *)path { //判断是否有文件 if([[NSFileManager defaultManager] fileExistsAtPath:[self getPath]]) { NSMutableArray *arr = [NSArray arrayWithContentsOfFile:[self getPath]]; return arr; } } - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { self.title = @"子视图"; // NSArray *arr = @[@"返回上一级",@"小花",@"小李",@"小王",@"小丁",@"小张",@"小康",@"小刘",@"小墩",@"大墩"]; // self.array = [arr mutableCopy]; // if ([self writeDataToFile:[self getPath] DataSource:self.array]) { // NSLog(@"success"); // } //获取数据 self.array = [self getDataFromFile:[self getPath]]; } return self; } - (void)viewDidLoad { [super viewDidLoad]; //首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑 UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:@"添加" style:UIBarButtonItemStyleBordered target:self action:@selector(itemLeftButtonClick:)]; self.navigationItem.leftBarButtonItem = button; UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithTitle:@"删除" style:UIBarButtonItemStyleBordered target:self action:@selector(itemRightButtonClick:)]; self.navigationItem.rightBarButtonItem = button1; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.array count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *identifier = @"Identifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier]; } int row = [indexPath row]; cell.textLabel.text = self.array[row]; return cell; } -(void)itemLeftButtonClick:(id)sender { //设置可以编辑 RIGHTBUTTON = false; [self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态 if (self.tableView.editing) { [self.navigationItem.leftBarButtonItem setTitle:@"完成"]; } else { [self.navigationItem.leftBarButtonItem setTitle:@"添加"]; } } -(void)itemRightButtonClick:(id)sender { RIGHTBUTTON = true; //设置可以编辑 [self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态 if (self.tableView.editing) { [self.navigationItem.rightBarButtonItem setTitle:@"完成"]; } else { [self.navigationItem.rightBarButtonItem setTitle:@"删除"]; } } //设置编译图标 -(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { //删除 if (RIGHTBUTTON) { return UITableViewCellEditingStyleDelete; } else { return UITableViewCellEditingStyleInsert; //return UITableViewCellEditingStyleNone; } } //设置是否可以移动 -(BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { if (RIGHTBUTTON) { return NO; } else { if (indexPath != 0) { return YES; } } } -(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { if ([indexPath row] == 0) { return NO; } else { return YES; } } //实现UIAlertView代理协议 -(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { //获取AlertView中的数据 NSString *str = [alertView textFieldAtIndex:0].text; //将数据插入到array数组中（位置是点击的位置的下一行） [self.array insertObject:str atIndex:[self.indexPath row]+1]; //用点击位置的下一行创建一个新的NSIndexPath int newrow = [self.indexPath row]+1; NSIndexPath *index = [NSIndexPath indexPathForRow:newrow inSection:0]; //在tableView的这个NSIndexPath中插入数据 [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:index] withRowAnimation: UITableViewRowAnimationFade]; [self writeDataToFile:[self getPath] DataSource:self.array]; } -(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { //删除按钮 if (RIGHTBUTTON) { if ([indexPath row] != 0) { int row = [indexPath row]; [self.array removeObjectAtIndex:row]; [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationMiddle]; [self writeDataToFile:[self getPath] DataSource:self.array]; } } //添加按钮 else { //获得点击的indexPath self.indexPath = indexPath; //创建一个UIAlertView,用来获得数据 UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"enterstring" message:nil delegate:self cancelButtonTitle:@"ok" otherButtonTitles: nil]; //带有输入框的UIAlertView alert.alertViewStyle = UIAlertViewStylePlainTextInput; [alert show]; } } //可以根据行来设置delete按钮位置上button的标题 -(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath { return @"你删我一个试试"; } -(void)dealloc { [self.array release]; [self.indexPath release]; [super dealloc]; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if ([indexPath row] == 0) { [self.navigationController popToRootViewControllerAnimated:YES]; } else { EditViewController *edit = [[EditViewController alloc] init]; edit.sname = self.array`indexPath row`; edit.row = indexPath.row; edit.delegate = self; [self.navigationController pushViewController:edit animated:YES]; } //蓝色背景消失 [tableView deselectRowAtIndexPath:indexPath animated:YES]; } -(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath { if (!RIGHTBUTTON) { if ([destinationIndexPath row]!=0) { id object= self.array`sourceIndexPath row`; [self.array removeObject:self.array`sourceIndexPath row`]; [self.array insertObject:object atIndex:[destinationIndexPath row]]; NSLog(@"%d",[self.array count]); NSLog(@"当前位置%d,目标位置%d",[sourceIndexPath row],[destinationIndexPath row]); [self writeDataToFile:[self getPath] DataSource:self.array]; } //如果是跟第一行移动，则不允许这样操作，重新加载数据 [self.tableView reloadData]; } } //实现遵循协议的方法 -(void)changeData:(int)row Name:(NSString *)name { [self.array replaceObjectAtIndex:row withObject:name]; [self writeDataToFile:[self getPath] DataSource:self.array]; [self.tableView reloadData]; } @end
3.创建一个可以修改的viewController With xib，命名为：EditViewController
![]()
EditViewController.h:
#import <UIKit/UIKit.h> #import "DXWViewController.h" @interface EditViewController : UIViewController @property (retain, nonatomic) IBOutlet UITextField *name; @property(retain,nonatomic)NSString *sname; @property(assign,nonatomic) int row; - (IBAction)assignBoardClick:(id)sender; @property(nonatomic,retain)id<change>delegate; @end
EditViewController.m:
#import "EditViewController.h" #import "DXWViewController.h" @interface EditViewController () @end @implementation EditViewController //获取沙盒文件路径 -(NSString *)getPath { //用来获得Document地址 NSArray *arr = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);//注意：这里是NSDocument不是NSDocumentation,特别注意 NSLog(@"%@",arr); //在地址上增加文件 NSString *path = [arr[0] stringByAppendingPathComponent:@"abc.plist"]; NSLog(@"%@",path); return path; } - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { self.title = @"信息修改"; } return self; } -(void)viewWillAppear:(BOOL)animated { self.name.text = self.sname; } - (void)viewDidLoad { [super viewDidLoad]; //首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑 UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStyleBordered target:self action:@selector(itemLeftButtonClick:)]; //左按钮返回 self.navigationItem.leftBarButtonItem = button; //右按钮编辑保存并返回 UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithTitle:@"保存" style:UIBarButtonItemStyleBordered target:self action:@selector(itemRightButtonClick:)]; self.navigationItem.rightBarButtonItem = button1; //实现不按保存按钮也能够保存到文件的功能，获取应用 UIApplication *app = [UIApplication sharedApplication]; //在通知中心添加一个观察者，当符合UIApplicationWillResignActiveNotification条件时，调用方法 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(save:) name:UIApplicationWillResignActiveNotification object:app]; } -(void)save:(id)sender { self.sname = self.name.text; if ([self.delegate respondsToSelector:@selector(changeData:Name:)]) { [self.delegate changeData:self.row Name:self.sname]; } } //返回 -(void)itemLeftButtonClick:(id)sender { [self.navigationController popViewControllerAnimated:YES]; } //保存 -(void)itemRightButtonClick:(id)sender { [self changedata]; [self.navigationController popViewControllerAnimated:YES]; } - (void)changedata { self.sname = self.name.text; if ([self.delegate respondsToSelector:@selector(changeData:Name:)]) { [self.delegate changeData:self.row Name:self.sname]; } } - (IBAction)assignBoardClick:(id)sender { [sender resignFirstResponder]; } - (void)dealloc { [_name release]; [super dealloc]; } @end
