我在Swift中定义了一个这样的类:classRecordedAudio:NSObject{vartitle:String!varfilePathUrl:NSURL!init(title:String,filePathUrl:NSURL){self.title=titleself.filePathUrl=filePathUrl}}之后，我在Controller中声明了这个的全局变量varrecordedAudio:RecordedAudio!然后，在此函数中创建实例:funcaudioRecorderDidFinishRecording(recorder:AVAudioRecorder

我在新文件中创建了一个新的Swift类importFoundationclassRecordedAudio:NSObject{varfilePathUrl:NSURL!vartitle:String!}现在我想通过创建一个新对象在另一个类中使用它。importUIKitimportAVFoundationclassrecordSoundsViewController:UIViewController,AVAudioRecorderDelegate{varaudioRecorder:AVAudioRecorder!varrecordedAudio:RecordedAudio!//newo
