[IOS]包含增删改查移动的tableView展示+plist文件保存+程序意外退出保存Demo

#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

#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
