[IOS]包含增刪改查移動的tableView展示+plist文件保存+程序意外退出保存Demo

發布時間:2020-07-16 13:35:09 來源:網絡 閱讀:499 作者:蓬萊仙羽 欄目:移動開發

做一個tableView,包含增刪改移動功能,并且修改值的時候,在按home鍵的時候會自動保存。如果可以的話使者保存自定義的類數組保存到plist中。

實現步驟:

1.創建一個SingleViewApplication的項目,首頁命名為FirstViewController

[IOS]包含增刪改查移動的tableView展示+plist文件保存+程序意外退出保存Demo

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 = @"目錄列表";     }     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;     //有右邊的>符號     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.創建二級子視圖控制器,不帶xib文件,命名DXWViewController

EditViewController.m:

#import "EditViewController.h" #import "DXWViewController.h" @interface EditViewController ()  @end  @implementation EditViewController //獲取沙盒文件路徑  -(NSString *)getPath  {          //用來獲得Document地址          NSArray *arr = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);//注意:這里是NSDocument不是NSDocumentation,特別注意          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個edit按鈕,按鈕按下去可以設置可以編輯     UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStyleBordered target:self action:@selector(itemLeftButtonClick:)];     //左按鈕返回 	self.navigationItem.leftBarButtonItem = button;     //右按鈕編輯保存并返回     UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithTitle:@"保存" style:UIBarButtonItemStyleBordered target:self action:@selector(itemRightButtonClick:)];     self.navigationItem.rightBarButtonItem = button1;          //實現不按保存按鈕也能夠保存到文件的功能,獲取應用     UIApplication *app = [UIApplication sharedApplication];     //在通知中心添加一個觀察者,當符合UIApplicationWillResignActiveNotification條件時,調用方法     [[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
