我正在开发一个基于网络的应用程序, 只有当我的服务器为特定主机服务时才需要启动该应用程序。 如果网络连接不可用, 我正计划显示一个重新启动应用程序的警告视图 。 我使用此选项 :
NSURL *scriptUrl = [NSURL URLWithString:@"http://lmsstaging.2xprime.com"];
NSData *data = [NSData dataWithContentsOfURL:scriptUrl];
if (data != nil) {
//Launch my application
}
else {
//show an alert
}
但问题是,当我点击警示视图中的“ 好” 按钮时, 我希望我的应用程序退出。 这是这样做的正确方式吗? 有人可以建议其他选项来克服这一情形吗?
不存在“ 官方” 退出方式。 苹果建议您警告要说 : “ 此应用程序需要网络连接。 按主按钮退出 。 ”
