截屏

我照着Native.js的例子这样写的:

function userDidTakeScreenshot( notification ){  
    console.log("已经截图");  
 }  
mui.plusReady(function(){  
    if ( plus.os.name == "iOS" ) {  
          NSNotificationCenter = plus.ios.importClass("NSNotificationCenter");  
          var nc = NSNotificationCenter.defaultCenter();  
          var delegate = plus.ios.implements("NSObject",{"userDidTakeScreenshot:":userDidTakeScreenshot});  
          nc.addObserverselectornameobject(delegate,  
                plus.ios.newObject("@selector","userDidTakeScreenshot:"),  
                "UIApplicationUserDidTakeScreenshotNotification",  
                null);  
    } else {  
      alert("Android");  
    }  
}

但是一截屏,程序就崩溃退出了,而且hbuilder中看不到崩溃日志. 求问怎么解决?
