open（{modal：true}）拋出NSException

我收到一個NSException，當我點擊我的rightNavButton嘗試打開一個新窗口。但是，當我這樣做時，它突然退出模擬器，並給我一個NSException錯誤。我已經完成了有關該主題的研究並沒有遇到同樣的問題。open（{modal：true}）拋出NSException

var btnCart = Titanium.UI.createButton({

btnCart.addEventListener('click', function(e){

win.rightNavButton = btnCart;

如果任何機構都知道這個問題，或者已經有它的過去和已固定的：我試圖打開不具有任何錯誤，這是我不斷收到錯誤我的js文件它請儘快讓我知道！

謝謝

能否請你告訴你的代碼？ –

@MuhammadZeeshan我在錯誤代碼 –

的底部添加了代碼請參見異常終結應用程序由於未捕獲的異常'NSInternalInconsistencyException'，原因：'試圖開始從到，而轉換已經在進行中。等待viewDidAppear/viewDidDisappear以知道當前轉換已完成。在我看來，你目前的窗口正在做一些處理。 –

我在應用程序中遇到了類似的崩潰。

我只是像實施睡眠方法：

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

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

，並打開窗戶像以前一樣把它稱爲：

sleep(1000); 
myWin.open();
