现场:在使用摄像机时将动物放到部分屏幕上
原标题:iOS: Zoom in to part of screen when using camera

我正在使用<代码>UIImagePickerController在屏幕上播放录像。 是否有办法把一部分实况录像带上去? 例如,录像的正段?

如果有可能,如何?

最佳回答

传真机组有财产:

@property (nonatomic) CGAffineTransform cameraViewTransform

CGAffine Transform有文件记载:http://developer.apple.com/library/mac/#documentation/GraphicsImaging/Reference/CGAffine Transform/Reference/ reference.html“rel=“nofollow”>,载于

铭记这只会改变对屏幕上摄像材料的介绍。 绘制产出图是另一个问题,但照相转换财产也可以帮助你。
