ios - 应用程序可以在模拟器上运行，但不能在设备上运行。Https Web 服务问题

Question

我在我的应用程序中通过 Post 网络服务获取数据。当我在模拟器上运行该应用程序时它似乎工作正常但在设备上失败。该服务以 https .. 开头，所以你们认为这可能是原因。我在设备上运行时的响应数据为空，因此应用程序崩溃......这是我的代码，用于使用 Web 服务和获取数据......

如有任何关于如何使用 https 服务的帮助，我们将不胜感激。

    NSURL *url1 = [NSURL URLWithString:urlname];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url1 cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:60.0];
