IOS开发（54）之Storyboard之传值

1 前言

上一次我们介绍了Storyboard的简单创建方法，这次我们来介绍一下如何通过Storyboard进行两个ViewController之间的传值。

2 代码实例

2.1 新建一个不带nib文件ViewController文件

2.2 将Storyboard中的第二个视图控制器的类设置为新建的SecondView

2 .3 为视图过度的Segue标识设置一个名称

ZYViewController.m

 //通知视图控制器,继续将被执行。UIStoryboardSegue：一个UIStoryboardSegue对象负责执行过渡两视图控制器。
 - (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
     //原视图控制器
     NSLog(@"Source Controller = %@", [segue sourceViewController]);
     //目标视图控制器
     NSLog(@"Destination Controller = %@", [segue destinationViewController]);
     //过渡标识
     NSLog(@"Segue Identifier = %@", [segue identifier]);
     if ([[segue identifier] isEqualToString:@"SimpleSegueToSecondViewController"]){
         ZYSecondViewController *viewController = [segue destinationViewController];
         viewController.str = @"sdfsdfdsfdsfs";
     }
 }

ZYSecondViewController.h

 #import <UIKit/UIKit.h>

 @interface ZYSecondViewController : UIViewController

 @property(nonatomic,copy)NSString *str;

 @end

ZYSecondViewController.m

 - (void)viewDidLoad
 {
     [super viewDidLoad];
     // Do any additional setup after loading the view.
     //Test
     NSLog(@"str=======>%@",str);
 }

 -(void)dealloc{
     [str release];
     [super dealloc];
 }

运行结果：

点击Button后控制台结果：

2013-05-09 14:10:15.850 StoryboardsTest[610:c07] Source Controller = <ZYViewController: 0x75668d0>

2013-05-09 14:10:15.850 StoryboardsTest[610:c07] Destination Controller = <ZYSecondViewController: 0x8e25730>

2013-05-09 14:10:15.851 StoryboardsTest[610:c07] Segue Identifier = SimpleSegueToSecondViewController

2013-05-09 14:10:15.852 StoryboardsTest[610:c07] str=======>sdfsdfdsfdsfs

3 结语

以上就是主要内容，希望对大家有所帮助。
