如何檢測和實現單擊主頁按鈕上的觸摸事件？

Question

不確定是否有可能，但有什麼方法可以檢測到主頁按鈕上的單點觸摸。首先，我只想添加一個NSLog，如果用戶在home按鈕上觸摸一次（沒有實際按下），但我不知道在哪裏添加這個功能。 Apple允許您與主頁按鈕進行交互嗎？

我看了一下應用程序的委託方法，但我看不到在單擊（觸摸）上下文中有任何工作方式。非常感謝你的幫助。

不，還沒有。沒有任何API可用於明確檢測主頁按鈕交互。
您可以依靠傳統的app delegate生命週期函數調用來執行您想要的任何邏輯。

- (void)applicationWillResignActive:(UIApplication *)application 
{ 
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. 
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game. 
} 

- (void)applicationDidEnterBackground:(UIApplication *)application 
{ 
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. 
} 

- (void)applicationWillTerminate:(UIApplication *)application 
{ 
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:. 
}
