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，它不会通过google.com呈现控制器。有人可以帮忙吗？

- (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;
}

Answer 1

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;
}

Answer 2

试试这个

 - (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演示代码移动到viewDidAppear的RootViewController。如果您的RootViewController是UINavigationController，请将其移至导航控制器的viewDidAppear的topViewController
