var AVSpeechSynthesizer = plus.ios.importClass("AVSpeechSynthesizer");  
            var AVSpeechUtterance = plus.ios.importClass("AVSpeechUtterance");  
            var AVSpeechSynthesisVoice = plus.ios.import("AVSpeechSynthesisVoice");  
            var sppech = new AVSpeechSynthesizer();  
            var voice = AVSpeechSynthesisVoice.voiceWithLanguage("zh-CN");  
            var utterance =  AVSpeechUtterance.speechUtteranceWithString("哈哈哈哈哈");   
                       var delegate = plus.ios.implements("AVSpeechSynthesizerDelegate",  
                            {"speechSynthesizer:didFinishSpeechUtterance:":function(){  
                                  console.log('info:已完成');  
                            }});  

                        sppech.plusSetAttribute('delegate', delegate);  
               // utterance.plusSetAttribute("rate",30.1);  
            utterance.setVoice(voice);  
            sppech.speakUtterance(utterance);  
            plus.ios.deleteObject(voice);  
            plus.ios.deleteObject(utterance);  
            plus.ios.deleteObject(sppech);

如上代码，添加监听播放完成代码会闪退，求解决方案，或者其他方法监听播放完成事件
