方式一：通過定義一個實體類傳值 (從ViewController1 跳轉至 ViewController2)

1、定義實體類NotificationEntity

.h聲明文件

#import

@interface NotificationEntity : NSObject

{

}

@property (nonatomic,retain) NSString *strTitle; //參數一

@property (nonatomic,retain) NSString *strContent; // 參數二

@property (nonatomic,retain) NSString *strUrl; //參數三

@end

.m實現文件

#import "NotificationEntity.h"

@implementation NotificationEntity

@synthesize strTitle=_strTitle;

@synthesize strContent=_strContent;

@synthesize strUrl=_strUrl;

@end

2、在ViewController2中

在.h文件中聲明實體類NotificationEntity為ViewController2的類成員變量：

@property (retain,nonatomic) NotificationEntity *mNotifEntity;

在.m文件中通過@synthesize為成員變量mNotifEntity合成存取方法：

@synthesize mNotifEntity=_mNotifEntity;

3、在ViewController1中實現跳轉並傳遞參數

// 組裝實體類的實例變量

NotificationEntity *mNotificationEntity = [[NotificationEntity alloc] init];

[mNotificationEntity setStrTitle:strTitle];

[mNotificationEntity setStrContent:strContent];

[mNotificationEntity setStrUrl:strUrl];

// 實例化ViewController2

ViewController2 *viewController2 = [[ViewController2 alloc] init];

// 注入參數

[viewController2 setMNotifEntity:mNotificationEntity];

// 跳轉

[self.window.rootViewController presentModalViewController:viewController2 animated:YES];

4、在ViewController2中接收參數：

- (void)viewDidLoad

{

[super viewDidLoad];

[self.lblTitle setText:[self.mNotifEntity strTitle]];

[self.lblContent setText:[self.mNotifEntity strContent]];

}

5、在ViewController2中加入返回ViewController1的事件：

- (IBAction)backOff:(id)sender

{

[self dismissModalViewControllerAnimated:YES];

}
