iOS屏幕镜像显示所选应用程序的过扫描边框 [英] iOS screen mirroring shows overscan borders on selected apps

问题描述

问题:iPhone屏幕镜像&我的应用程序的专用外部视图在所有侧面都显示一英寸的黑色边框.

Problem: iPhone screen mirroring & a dedicated external view of my app show an inch of a black border on all sides.

但是:某些视图在全屏上显示完美，没有黑色边框，例如Apple TV菜单和照片应用程序.

But: Some views display perfect without black borders on the full-screen, e.g., the Apple TV menu and the photo app.

已经尝试-无效:

• 在1080p高清电视上禁用过扫描(禁用16:9过扫描")( IOS-外部(hdmi)输出仅填充屏幕的一半，除非手动编码视图时)

• Disabled overscan on 1080p HD TV ("Disable 16:9 overscan") ( iPad Mirroring using 2 screens, does it support 1080 resolution? )
• set UIScreenOverscanCompensation - has no effect ( IOS - External (hdmi) output fills only half the screen except when coding view manually )

设置:iPhone 4S(5.0.1)，Apple TV 2nd generation(4.4.4)

Setup: iPhone 4S (5.0.1), Apple TV 2nd generation (4.4.4)

有什么建议可以尝试吗?

Any suggestions what I could try additionally?

推荐答案

遇到同样的问题，花了一段时间才找到解决方案".原来，您可以将overscanCompensation设置为'3'，它将删除边框.

Ran into the same issue and it took a while to find the 'solution'. Turns out you can set the overscanCompensation to '3' and it will remove the borders.

我认为Apple只是忽略了文档& UIScreenOverscanCompensationNone的枚举，但在代码中对其进行了检查.

I think Apple just left out the documentation & enum for UIScreenOverscanCompensationNone, but that down in the code they check for it.
