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

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

     NSString *view2 = @"goToView2";
     NSString *view3 = @"goToView3";

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

         UIViewController *send = segue.destinationViewController;

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

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

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

         UIViewController *send = segue.destinationViewController;

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

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

         }
     }else{
         NSLog(@"nothing");
     }
 }
