EditViewController.h:

#import  #import "Person.h" #import "ChangeViewController.h" @interface EditViewController : UIViewController @property(copy,nonatomic)Person *per;//对象 @property (retain, nonatomic) IBOutlet UITextField *name; @property (retain, nonatomic) IBOutlet UITextField *age; @property(assign,nonatomic) int row; //位置 @property(nonatomic,retain)iddelegate; @end

EditViewController.m:

#import "EditViewController.h"  @interface EditViewController ()  @end  @implementation EditViewController  - (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.per.name;     self.age.text = [NSString stringWithFormat:@"%d",self.per.age]; }  - (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:)]; 	self.navigationItem.leftBarButtonItem = button;          UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithTitle:@"保存" style:UIBarButtonItemStyleBordered target:self action:@selector(itemRightButtonClick:)];     self.navigationItem.rightBarButtonItem = button1; } //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.per.name = self.name.text;     self.per.age = [self.age.text intValue];     if ([self.delegate respondsToSelector:@selector(changeData:Per:)]) {         [self.delegate changeData:self.row Per:self.per];     } }  - (void)dealloc {     [_name release];     [_age release];     [super dealloc]; } @end
