ios - Appdelegate presentviewcontroller

Question

我正在尝试使用以下内容显示网页 google.com。出于某种原因，它没有向 google.com 提供控制器。任何人都可以帮忙吗？

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    SFSafariViewController *vc = [[SFSafariViewController alloc] initWithURL:[NSURL URLWithString:@"https://www.google.com"]];
    [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:vc animated:YES completion:nil];
    return YES;
}

我认为这应该有效：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    SFSafariViewController *vc = [[SFSafariViewController alloc] initWithURL:[NSURL URLWithString:@"https://www.google.com"]];
    self.window.rootViewController = vc;
    return YES;
}

尝试这个

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

            SFSafariViewController *vc = [[SFSafariViewController alloc] initWithURL:[NSURL URLWithString:@"https://www.google.com"]];
            self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
        return YES;
    }

将SafariViewController演示文稿代码移动到viewDidAppear您的RootViewController. 如果您RootViewController是 a UINavigationController，请将其移至viewDidAppear导航控制器的topViewController
