iOS 5 Segue 实现

在两个视图控制器之间实现 segue 时，如何使用 segue 对象更改目标视图控制器的属性？文档说这可以在prepareForSegue:sender:方法中完成。我尝试过但没有成功

我不知道你是否还需要这个答案，但这是一个如此孤独的帖子，如果我是对的，这不再属于保密协议。如果我错了，请缓和我的答案，让我们忘记，所以我们开始：我刚刚完成了一些使用你需要的东西。这是适合我的代码：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"relevantSegueIdentifier"])
    {
        // [segue destinationViewController] is read-only, so in order to
        // write to that view controller you'll have to locally instantiate
        // it here:
        ViewController *upcomingViewController = [segue destinationViewController];
        
        // You now have a solid reference to the upcoming / destination view
        // controller. Example use: Allocate and initialize some property of
        // the destination view controller before you reach it and inject a
        // reference to the current view controller into the upcoming one:
        upcomingViewController.someProperty = [[SomePropertyClass alloc] initWithString:@"Whatever!"];
        upcomingViewController.initialViewController = [segue sourceViewController];
        // Or, equivalent, but more straightforward:
        //upcomingViewController.initialViewController = self;
    }
}

这假设 someProperty 和initialViewController 都是目标视图控制器的合成访问器。希望这可以帮助！
