每年iOS更新後，SDK中多少會有些API在最新的版本被棄用，此時就要去寫condition code分別跑在不同版本的iOS。Notification也在iOS 8有所變動，包含Remote Notification與Local Notification，我們就來看怎麼改比較容易吧～
如果沒有處理iOS 8的情況，是不會跳出請求允許傳送通知的提示喔！
Remote Notification可以這麼寫：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// ---------------------------------------------------------------------- //
// 向 Apple 註冊並取得 token
// ---------------------------------------------------------------------- //
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
}
Local Notification可以這麼做：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// The following line must only run under iOS 8. This runtime check prevents
// it from running if it doesn't exist (such as running under iOS 7 or earlier).
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
}
}
可以發現，Local Notification在iOS 7以前不用寫任何註冊的code，iOS 8以後才開始要寫呢！
加入處理iOS 8的Local Notification後，總算能像iOS 7以前那樣跳出提醒該丟垃圾的提示囉～

您好：
請教您，在程式未啟動狀態下，進入app如何取得推播訊息？？
謝謝

好問題！
Remote和Local都可以在專案中的AppDelegate.m實作已定義的方法：
Remote：
– (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo NS_AVAILABLE_IOS(3_0);
Local：
– (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification NS_AVAILABLE_IOS(4_0);
