ios - 为编程 UINavigationController 制作文件？

Question

我制作了一个 UINavigationController，我让它工作得很好，但我现在需要使用它。我需要与 Controller 同步的文件。我以编程方式构建所有内容。

如何设置这些文件？

AppDelegate.h:

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) UINavigationController *navigationController;
@property (strong, nonatomic) UIViewController *rvc;

AppDelegate.m:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    self.navigationController = [[UINavigationController alloc] init];
    [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0/255 green:126/255 blue:233/255 alpha:1]];
    [self.window addSubview:[self.navigationController view]];

    [self.navigationController pushViewController:self.rvc animated:YES];

    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

    return YES;
}

创建一个 UIViewController 子类并使 rvc 属性具有该类的类型。之后你可以在创建的子类中编写你的逻辑。

正确的 didFinishLaunchingWithOptions 实现:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    self.navigationController = [[UINavigationController alloc] init];
    [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0/255 green:126/255 blue:233/255 alpha:1]];
    self.window.rootViewController = self.navigationController;

    self.rvc = [[<your_class_name> alloc] init];
    [self.navigationController pushViewController:self.rvc animated:YES];

    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

    return YES;
}
