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:)]) {
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{
26         NSLog(@"nothing");
27     }
28 }
