我正在尝试使用Xcode 6编译现有的应用程序。
这是我的代码:
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。
这是我对iOS 8的检查:
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];
答案 0 :(得分:8)
这样做:
#if __IPHONE_OS_VERSION_MIN_REQUIRED >= 80000
UIUserNotificationSettings *settings = [UIApplication.sharedApplication currentUserNotificationSettings];
#endif
