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");
    }
}
