正在进行通话时的iOS启动图像 [英] iOS Launch Image for when Call is in Progress

问题描述

我知道Apple的应用程序和一些第三方应用程序在通话进行时会修改启动图像.典型的启动映像是320x480(全屏)或320x460(减去状态栏)，但是如何为320x440(在进程栏中减去调用)设置额外的启动映像?

I know Apple's app and a few third party apps have a modified launch image for when a call is in progress. The typical launch image is either 320x480(full screen) or 320x460(minus status bar), however how do you have an additional launch image for 320x440(minus call in process bar)?

有人知道怎么做吗，看来这没有记载，但是苹果的应用程序和某些第三方应用程序(Twitter，Facebook，Tipulator)正在使用单独的启动映像来进行通话.

Does anyone know how this is done, it appears this is undocumented, however Apple's apps and some third party apps (Twitter, Facebook, Tipulator) are using a separate launch image for when a call is in progress.

更新:从应用程序添加这些图像.就像我们通过Facebook和Twitter徽标看到的那样，似乎所有人都在裁剪图像.

Update: Adding these images from the apps. It appears like they all are cropping the image as we see with the Facebook and Twitter Logo.

推荐答案

没有API(已记录文档或其他文档)可用于在进行呼叫时使用其他启动映像.您所看到的是开发人员按照文档中指定的说明进行操作后得到的结果，并且操作系统没有因此而裁剪图像.

There is no API, documented or otherwise, for using a different launch image when a call is in progress. What you’re seeing is the result of the developer following the directions specified in the documentation, and the OS not cropping their image as a result.

许多第三方开发人员选择包含裁剪后的320x460启动图像(省略了标准的高度为20像素的状态栏)，而不是文档指定的320x480全屏图像.发生这种情况时，如果状态栏处于双高模式，则操作系统将从图像中间裁切20个像素.

Many third-party developers opt to include a cropped 320x460 launch image (omitting the standard height 20 pixel status bar) instead of the documentation-specified 320x480 full screen image. When that happens, the OS will crop 20 pixels from the middle of the image if the status bar is in double-height mode.

解决方案::提供完整的320x480图片，并且状态栏为双倍高度时不会被裁剪.

Solution: Provide a full-size 320x480 image, and it will not be cropped when the status bar is double-height.
