open（{modal：true}）抛出NSException

问题描述：

我收到一个NSException，当我点击我的rightNavButton尝试打开一个新窗口。但是，当我这样做时，它突然退出模拟器，并给我一个NSException错误。我已经完成了有关该主题的研究并没有遇到同样的问题。open（{modal：true}）抛出NSException

win.rightNavButton = btnCart;

如果任何机构都知道这个问题，或者已经有它的过去和已固定的：我试图打开不具有任何错误，这是我不断收到错误我的js文件它请尽快让我知道！

谢谢

能否请你告诉你的代码？ –

@MuhammadZeeshan我在错误代码 –

的底部添加了代码请参见异常终结应用程序由于未捕获的异常'NSInternalInconsistencyException'，原因：'试图开始从到，而转换已经在进行中。等待viewDidAppear/viewDidDisappear以知道当前转换已完成。在我看来，你目前的窗口正在做一些处理。 –

答

我在应用程序中遇到了类似的崩溃。

我只是像实施睡眠方法：

function sleep(milliseconds) 
{ 
    var start = new Date().getTime(); 

    while((new Date().getTime() - start) < milliseconds) 
    { 
     // Do nothing 
    } 
}

，并打开窗户像以前一样把它称为：

sleep(1000); 
myWin.open();

open（{modal：true}）抛出NSException
