我正在尝试使用Xcode 6编译现有应用程序。
以下是我的代码：
UIUserNotificationSettings *settings = [UIApplication.sharedApplication currentUserNotificationSettings];
这是我的错误：
use of undeclared identifier 'UIUserNotificationSettings'
我不知道如何解决这个问题。
这是我的iOS 8检查：
if (SYSTEM_VERSION_LESS_THAN(_iOS_8_0)) {
// Displaying notifications and ringing
if ([self isMissingMandatoryNotificationTypes:[UIApplication.sharedApplication enabledRemoteNotificationTypes]]) {
[self registrationWithSuccess:^{
DDLogInfo(@"Push notifications were succesfully re-enabled");
} failure:^{
[self.missingPermissionsAlertView show];
}];
}
} else {
// UIUserNotificationsSettings
UIUserNotificationSettings *settings = [UIApplication.sharedApplication currentUserNotificationSettings];
