storyboard有多个Segue的传递

 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:)]) {
12             
13             [send setValue:@"view2" forKey:@"Str2"];
14             
15         }
16     }else if([[segue identifier] isEqual:view3]){
17         
18         UIViewController *send = segue.destinationViewController;
19         
20         if ([send respondsToSelector:@selector(setStr3:)]) {
21             
22             [send setValue:@"view3" forKey:@"Str3"];
23             
24         }
25     }else{
