Opentok: OTCameraCaptureResolutionswift 中的高等效变量

Question

我需要更改发布商的视频质量。 我面临着从Objective C 到 Swift 3.0 的转换问题。

这是我的目标 C 代码：

OTPublisherSettings *settings = [[OTPublisherSettings alloc] init];
settings.name = @"Bob's video";
settings.audioTrack = NO;
settings.videoTrack = YES;
settings.cameraResolution = OTCameraCaptureResolutionHigh;
settings.cameraFrameRate = OTCameraCaptureFrameRate30FPS;

转换后的 Swift 代码是

let settings = OTPublisherSettings()
settings.name = "Bob's video"
settings.audioTrack = false
settings.videoTrack = true
settings.cameraResolution = OTCameraCaptureResolutionHigh
settings.cameraFrameRate = OTCameraCaptureFrameRate30FPS

最后两行显示错误消息"使用未解析的标识符'OTCameraCaptureResolutionHigh'"。请指教。似乎 swift 对上述使用了另一组变量。

Answer 1

let settings = OTPublisherSettings()
settings.name = "Bob's video"
settings.audioTrack = false
settings.videoTrack = true
settings.cameraResolution = .high
settings.cameraFrameRate = .30fps
