我试图在我的ClientViewController.mm类中调用一个方法并不断收到此错误:由于未捕获的异常而终止应用程序
'NSInvalidArgumentException', reason: '+ [ClientViewController TestMethod]: 
 unrecognized selector sent to class 
我有另一个实现接口的类。
void AppleRecognitionStatusObserver::onRecognitionStatusChanged
                                       (RecognitionStatus newStatus) {
    switch(newStatus) {
        case kInProgress:
            [ClientViewController TestMethod];
            break;
        ....etc
    }
}
如何从另一个 C++ 类调用ClientViewController方法?
客户端视图控制器.h
//imports UIKit etc
@interface ClientViewController : UIViewController <AVAudioRecorderDelegate>{
    IBOutlet UIButton *recoButton;
    // some other buttons
}
@end
// and the .mm
//#imports....
@interface ClientViewController ()
@end
@implementation ClientViewController
-(void)TestMethod{
    outLabel.text = @"Has been called!";
}
