ios - 无法在 viewDidLoad 方法中获取传递的数据

Question

我正在尝试像这样将一些数据传递给我的 View Controller 类:

MyViewController *vc = [[MyViewController alloc] init];
vc.myProperty = dataToBePassed;
[self.navigationController pushViewController:vc animated:YES];

我需要在 viewDidLoad 中进行一些 View 配置，但似乎 viewDidload 调用早于属性分配。

然后在 MyViewController 实现中:

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSLog(@"%@", self.myProperty); // Here i get myProperty = nil
}

- (void)viewWillAppear
{
    [super viewWillAppear];
    NSLog(@"%@", self.myProperty); // Here i get myProperty = dataToBePassed but it's to late
}

如何在不实现单例或委托(delegate)模式的情况下在 viewDidLoad 方法中获取传递的数据？

Answer 1

尝试这样做

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:
                            @"MainStoryboard" bundle:[NSBundle mainBundle]];

MyViewController *vc = [storyboard  instantiateViewControllerWithIdentifier:@"storyboardIdentifier"];
vc.myProperty = dataToBePassed;
[self.navigationController pushViewController:vc animated:YES];

您必须首先在 View Controller 的 Storyboard中设置 Storyboard标识符。
