ios - 关闭应用程序并在 appstart 上启动 webview

Question

我已发出 api 请求以从我的后端服务获取一些详细信息:

我想关闭我当前的 View Controller 并通过来自后端的 url 启动一个新网页:

NSDictionary *parameters = @{@"X-Service-Code" : @"PP", @"Accept" : @"application/json", @"Content-Type" : @"application/json"};
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    [manager GET:url1 parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {


        NSMutableArray *jsonArray = [[NSMutableArray alloc]init];
        jsonArray = [NSJSONSerialization JSONObjectWithData: responseObject options:NSJSONReadingMutableContainers error:nil];


        [self dismissViewControllerAnimated:YES completion:nil];


        NSString *urlAddress = [[jsonArray objectAtIndex:10]valueForKey:@"value"];
        [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlAddress]]];


    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

Web View 正在后台启动，但 View Controller 并未被关闭。有什么建议吗？

dismissViewControllerAnimated 需要在主线程上调用:

dispatch_async(dispatch_get_main_queue(), ^{
    [self dismissViewControllerAnimated:YES completion:nil];
});
