移動版Safari使用Hammer.js時崩潰

2014-01-16 41 views

我正在爲iPad使用Javascript的多人遊戲。我爲多人遊戲使用Smartfox服務器，觸摸事件使用Hammer.js。我有在那裏，當我在我的遊戲的一個特定部分用錘子事件的問題移動版Safari使用Hammer.js時崩潰

，它崩潰移動Safari瀏覽器。它在個人電腦上運行得非常好，但在iPad上導致了崩潰。

這是我的代碼的一部分它發生在哪裏：

this.startButton.hammer().on("tap", this.handleStartClicked);

所有我在「handleStartClicked」功能做的是從輸入框獲取用戶名和密碼，並將其保存到本地存儲（如果可用），並調用Smartfox「連接」功能，該功能將用戶連接到Smartfox並開始登錄過程。下面是函數：

onStartClicked:function(e){ 
    if(this.nameInput.val() == "" || this.pwInput.val() == "") {return;} 

    this.startButton.unbind("click", this.onStartClickBind); 

    if(window.localStorage != null && window['localStorage'] != null){ 
    window.localStorage.username = this.nameInput.val(); 
    window.localStorage.password = this.pwInput.val(); 
    } 

    this.sfs.connect();

}

如果我點擊開始按鈕，移動Safari瀏覽器崩潰的時間約80％。即使它不會立即崩潰，它通常會在遊戲後期的某個時間點崩潰。但是，如果我從不點擊開始按鈕（例如，如果我只是在沒有觸摸交互的情況下自動啓動用戶），那麼崩潰就不會發生 - 即使在稍後的遊戲中也不會發生。我甚至嘗試徹底刪除啓動按鈕，只是將觸摸監聽器添加到整個文檔主體中，並且它仍然崩潰，所以它似乎沒有特別與按鈕有關的任何內容（它只是包裝在一個普通的HTML按鈕中jQuery對象）。

好奇的是，如果我改變Hammer.js事件到正規jQuery的事件：

this.startButton.bind("click", this.onStartClickBind);

移動Safari瀏覽器從未崩潰。不在開始點擊...不在遊戲中的任何點。它似乎解決了一切。另一個好奇的是，我在我的代碼的其餘部分使用了Hammer事件，但它似乎成爲一個問題的唯一地方就在於這一個處理程序。我對遊戲中這個處理程序與其他任何處理程序有什麼不同之處感到茫然，除非崩潰以某種方式與Mobile Safari，Hammer.js和Smartfox之間的交互有關。我在遊戲中向其他Hammer處理程序發送了Smartfox的呼叫，但它們不會使Safari宕機，所以這似乎不大可能。

另外，我有iPad的崩潰日誌下面，如果雞舍再點亮的問題：

看起來CFRelease失敗，可能是由於釋放的東西已經被釋放（雖然偏移CFRelease看起來奇怪的高點）。無論這真的必須是WebKit中的錯誤。你有沒有嘗試更新到更高版本的iOS？

另外我注意到你的代碼示例中，你是從「點擊」中解除綁定，而不是從「點擊」解除綁定。不知道這是否是故意的（大概只是一個複製粘貼問題，因爲我也注意到你附加「tap」到handleStartClicked，但你粘貼的功能是onStartClicked）。

我曾與移動Safari和HammerJS類似的問題，這是導致該隨機崩潰使用localStorage的的。我仍然不確定它爲什麼會發生，但是一旦我們將本地存儲抽象到其他地方，並與錘子聽衆一起使用均衡器，它就會奏效。

Hammer(this.startButton).on('press tap', function(){ 
    that.emit('handleClickStart', this.sfs); 
} 

Controller.prototype.__proto__ = EventEmitter2.prototype; 

Controller.prototype.handleClickStart = function(sfs){ 
    if (!credential) return; 

    storageLib.set('credentials', credentials); 

    sfs.connect(); 
}; 

var storageLib = { 
    localStorage: localStorage, 
    set: function(key, val) { 
     if(val instanceof Object) val = JSON.stringify(val); 
     this.localStorage.setItem(key, val); 
     return this.isSet(key); 
    }, 
    isSet: function(key){ 
     var item = this.localStorage.getItem(key); 
     if(item) return true; 
     else return false; 
    } 
};
