Question

我搜索了一个答案并找到了很多，但没有任何方法可以解决我的错误，大多数答案告诉我删除带有黄色感叹号的项目，但我找不到任何答案。

我的版本在运行iOS8的所有iOS模拟器中运行正常 - 但是一旦我尝试使用iOS7.1，无论选择手机/ ipad，它都会失败。

以下是错误日志：

关于如何解决这个问题的任何明确方向都非常受欢迎，因为我正在了解有关编码的更多信息。

Answer 1

根据Apple文档，registerUserNotificationSettings仅适用于iOS 8及更高版本。如果你想支持旧版本的iOS，你必须以其他方式实现这一点。

Answer 2

来自官方Apple文档

状况

适用于iOS 8.0及更高版本。此registerUserNotificationSettings方法使用不能用于ios7。

更新1

也许你可以使用

[[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

而不是registerUserNotificationSettings

iOS7.1中的应用程序失败 - 由于未捕获的异常＆＃39; NSInvalidArgumentException＆＃39;
