storyboard有多个Segue的传递

在项目中需要在一个页面向多个页面传不同的值。

在view2Controller和view3Controller中分别有相应的Str2和Str3

 1 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

 2 {

 3     

 4     NSString *view2 = @"goToView2";

 5     NSString *view3 = @"goToView3";

 6     

 7     if ([[segue identifier] isEqual:view2]) { //通过[segue identifier] 得到指向那个页面

 8         

 9         UIViewController *send = segue.destinationViewController;

10         

11         if ([send respondsToSelector:@selector(setStr2:)]) { //view2页面中的setStr2

12             

13             [send setValue:@"view2Value" forKey:@"Str2"];

14             

15         }

16     }else if([[segue identifier] isEqual:view3]){

17         

18         UIViewController *send = segue.destinationViewController;

19         

20         if ([send respondsToSelector:@selector(setStr3:)]) { //view3页面中的setStr3

21             

22             [send setValue:@"view3Value" forKey:@"Str3"];

23             

24         }

25     }else{

26         NSLog(@"nothing");

27     }

28 }
