iOS獲取AppIcon and LaunchImage's name(app圖標和啟動圖片名字)

2020-06-08 12:19mrr JAVA教程

這篇文章主要介紹了iOS獲取AppIcon and LaunchImage's name(app圖標和啟動圖片名字)的相關資料,非常不錯，具有參考借鑒價值，感興趣的朋友一起學習吧

在某種場景下，可能我們需要獲取app的圖標名稱和啟動圖片的名稱。比如說app在前臺時，收到了遠程通知但是通知欄是不會有通知提醒的，這時我想做個模擬通知提示，需要用到icon名稱；再比如在加載某個控制器時，想設置該控制器的背景圖片為啟動圖片，需要用到啟動圖片名稱。

　　而事實上icon圖片放在系統(tǒng)AppIcon文件夾里，啟動圖片放在系統(tǒng)LaunchImage文件夾里，取這些圖片的名稱和其他一般資源圖片名稱不一樣。

　　為了方便舉例子，咱們先簡單粗暴點

假設當前項目只支持iPhone設備，并且只支持豎屏；而且當前項目里已經(jīng)設置好了AppIcon圖標和啟動圖片，

如何獲取icon圖標名稱和啟動圖片名稱呢 ？

上代碼和打印日志：

}

看到了，項目AppIcon圖標和啟動圖片信息，都可以從 [[NSBundle mainBundle] infoDictionary] 獲得，當前這里面還包含了app的其他信息如版本、app名稱、設備類型、支持方向。。。

打印所有信息看看：

---------- 接下來我們再來在app既支持iPhone和iPad設備，又支持橫屏和豎屏時，AppIcon和LaunchImage是怎樣的以及如何獲取 ---

先上兩張圖，再上測試代碼：

iOS獲取AppIcon and LaunchImage's name(app圖標和啟動圖片名字)

iOS獲取AppIcon and LaunchImage's name(app圖標和啟動圖片名字)

iOS獲取AppIcon and LaunchImage's name(app圖標和啟動圖片名字)

  AppIcon76x76,
  "AppIcon83.5x83.5"
 )
 iconLastName: AppIcon83.5x83.5
 */
}

2、獲取在支持iPhone和iPad開發(fā)，支持橫屏和豎屏時，獲取啟動圖片，并設為背景圖片代碼

(iPhone設備只有在Plus, 即5.5英寸才有豎屏和橫屏兩套圖片，其他4、5、6豎屏橫屏共用一張啟動圖片)
