應用程序didFinishLaunchingWithOptions`或applicationDidBecomeActive

Question

我想知道如何提供用戶從服務器下載內容的方式。

我的意思是如果用戶訂閱了一個月，我想每天發送一個新內容（歌曲）。但我不確定如何處理這個問題。

我是否需要調用web服務的application didFinishLaunchingWithOptions或 - (void)applicationDidBecomeActive:(UIApplication *)application {

請讓我知道我應該使用哪一個對於這種情況。

非常感謝您的幫助

如果你在開始一個新的連接計劃時，應用程序啓動，那麼你要使用

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    // Override point for customization after application launch. 
    return YES; 
} 

然而，applicationDidBecomeActive更適合當您的應用程序停止後臺時，恢復您暫停的下載。在這裏開始下載也可以接受。

- (void)applicationDidBecomeActive:(UIApplication *)application 
{ 
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. 
}
