当尝试在 iOS 8.x 下注册推送通知时：
application.registerForRemoteNotificationTypes(UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound)
我收到以下错误：
registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later.
有什么想法吗？新的做法是什么？当我在 iOS 7.x 上运行这个 Swift 应用程序时，它确实有效。
EDIT
在 iOS 7.x 上，当我包含我得到的条件代码时（SystemVersion 条件或 #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000）
dyld: Symbol not found: _OBJC_CLASS_$_UIUserNotificationSettings
对于 iOS
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
//-- Set Notification
if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
// iOS 8 Notifications
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[application registerForRemoteNotifications];
}
else
{
// iOS < 8 Notifications
[application registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
}
//--- your custom code
return YES;
}
适用于iOS10
