iOS获取AppIcon and LaunchImage's name(app图标和启动图片名字)

2020-06-08 12:19mrr JAVA教程

这篇文章主要介绍了iOS获取AppIcon and LaunchImage's name(app图标和启动图片名字)的相关资料,非常不错，具有参考借鉴价值，感兴趣的朋友一起学习吧

在某种场景下，可能我们需要获取app的图标名称和启动图片的名称。比如说app在前台时，收到了远程通知但是通知栏是不会有通知提醒的，这时我想做个模拟通知提示，需要用到icon名称；再比如在加载某个控制器时，想设置该控制器的背景图片为启动图片，需要用到启动图片名称。

　　而事实上icon图片放在系统AppIcon文件夹里，启动图片放在系统LaunchImage文件夹里，取这些图片的名称和其他一般资源图片名称不一样。

　　为了方便举例子，咱们先简单粗暴点

假设当前项目只支持iPhone设备，并且只支持竖屏；而且当前项目里已经设置好了AppIcon图标和启动图片，

如何获取icon图标名称和启动图片名称呢 ？

上代码和打印日志：

}

看到了，项目AppIcon图标和启动图片信息，都可以从 [[NSBundle mainBundle] infoDictionary] 获得，当前这里面还包含了app的其他信息如版本、app名称、设备类型、支持方向。。。

打印所有信息看看：

---------- 接下来我们再来在app既支持iPhone和iPad设备，又支持横屏和竖屏时，AppIcon和LaunchImage是怎样的以及如何获取 ---

先上两张图，再上测试代码：

iOS获取AppIcon and LaunchImage's name(app图标和启动图片名字)

iOS获取AppIcon and LaunchImage's name(app图标和启动图片名字)

iOS获取AppIcon and LaunchImage's name(app图标和启动图片名字)

 )
 iconLastName: AppIcon83.5x83.5
 */
}

2、获取在支持iPhone和iPad开发，支持横屏和竖屏时，获取启动图片，并设为背景图片代码

(iPhone设备只有在Plus, 即5.5英寸才有竖屏和横屏两套图片，其他4、5、6竖屏横屏共用一张启动图片)
