Ios 从Swift调用目标C方法

我正在Swift中构建一个应用程序，该应用程序导入一些.h文件。我有以下定义：

RTCEAGLVideoView.h

@interface RTCEAGLVideoView : UIView <RTCVideoRenderer>

   @property(nonatomic, weak) id<RTCEAGLVideoViewDelegate> delegate;

@end

但我得到了一个错误：

Value of type 'RTCVideoRenderer' has no member 'renderFrame'

任何帮助都将不胜感激

编辑： RTCI420Frame.h

#import <Foundation/Foundation.h>

// RTCI420Frame is an ObjectiveC version of cricket::VideoFrame.
@interface RTCI420Frame : NSObject

@property(nonatomic, readonly) NSUInteger width;
@property(nonatomic, readonly) NSUInteger height;

@property(nonatomic, readonly) const uint8_t* vPlane;

我试图复制您的问题，但使用虚拟文件对我来说效果很好。我怀疑您的问题不是桥接所有依赖的头

呈现桥接头.h

文件中的差异

您是否一直在使用桥接头？@EvgenyKarkan是的，我在其上添加了“RTCEAGLVideoView.h”。您是否也可以发布“RTCI420Frame”包含的内容？它可能会阻止该方法在swift中可用。@nickromano已完成。可能与的重复
