在故事板上，视图和传递数据 [英] On storyboards, views and passing data along

问题描述

在我的 Xcode 4.2 故事板中，我有 2 个 UIViewControllers、This one time 和 In band camp

In my Xcode 4.2 storyboard, i have 2 UIViewControllers, This one time and In band camp

• 在这一次中，我有一个带有傻名字"的UIButton
• 在In band camp中，我有一个带有label"的UILabel

• In This one time, i have a UIButton with "silly name" on it
• In In band camp, i have a UILabel with "label" on it

考虑到我们正在处理 2 个独立的类 AND 我们在 Xcode 4.2 中使用 storyboards(其中设置了视图之间的转换通过 segue)我如何将愚蠢的名字"从视图控制器 This one time 传递到视图控制器 In band camp 中的标签?"

Considering that we're dealing with 2 separate classes AND we're in Xcode 4.2 using storyboards (where transition between views is setup via a segue) how can i pass "silly name" from view controller This one time to the label in view controller In band camp?"

推荐答案

1. 将storyboard中segue的标识符设置为AwesomeSegue"
2. 实现 prepareForSegue 方法

3. 在方法内部，检查segue的标识符是否与AwesomeSegue"匹配——如果是，使用destinationViewControllerObject

1. Set the identifier of segue in storyboard to "AwesomeSegue"
2. Implement prepareForSegue method

3. Inside the method, check if identifier of segue matches "AwesomeSegue" - if yes, use the destinationViewControllerObject

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"AwesomeSegue"]) {
        InBandCampViewController *ibcVC = [segue destinationViewController];
        ibcVC.yourData = self.someStuff;
    }
}
