使用MPMoviePlayerViewController的時髦錯誤

有誰知道這些錯誤是什麼意思？當我點擊一個按鈕來播放視頻時，我會得到這個（通過網絡按需下載）。使用MPMoviePlayerViewController的時髦錯誤

我遇到的問題是我的視頻沒有音頻播放。實際上音頻音量欄在加載時會完全消失。

我有這事做這些錯誤嘿的感覺。

在設備上運行時，或者只是在模擬器上出現這些錯誤嗎？我想我在模擬器上看到過這樣的錯誤，但從來沒有在設備上看到。 – joerick

有趣。不，只是模擬器。 – crewshin

我想他們只是代表在模擬器中不能再現的功能的框架 - 看着它，這都是與硬件相關的東西。所以我猜測它與你的問題沒有任何關係...... – joerick

HDA是音頻格式（http://en.wikipedia.org/wiki/Intel_High_Definition_Audio）。由於Mac使用不同的音頻和視頻驅動程序，因此某些情況下音頻或視頻類型將無法在模擬器中播放，因爲它實際上並未實現設備上的完整軟件堆棧。在這種情況下，它看起來像您的視頻所使用的HDA音頻驅動程序在Mac上不可用。

這並不意味着您的Mac不能播放音頻HDA只是內部監督辦公室尋找的插件是不可用的。所以它只是禁用視頻的音頻部分並繼續播放。

歷史你以前不能夠在模擬器上播放YouTube視頻，而他們將努力在設備正常。這又是一個缺少插件的情況。較新版本的iOS模擬器有一個存根插件，用於轉換Mac的能力和模擬器如何訪問它們。

您是否在項目的構建設置中添加了提到的框架？

對我來說，它看起來像框架是不存在於你的二進制文件引用。

添加所需的框架，你可以做以下步驟：

在Xcode
打開項目，在項目導航
點擊根項目選擇目標
轉到Build Phases並展開Link with libraries
確保提到的框架在此處列出。
如果它們不存在添加它們，重建你的App

我希望這有助於

好吧，我又想過了。如果它在設備上工作，那麼我的建議可能不是你正在尋找的，因爲如果框架沒有與你的項目鏈接，那麼它在任何情況下都不起作用... – Besi

沒錯。這是編譯最新的Xcode時發生的事情。由於某些原因，Sim沒有看到Sim的正確框架 – Jann

音量欄應該走 - 因爲它是連接到粗線路輸出碼頭它的表現設備。請確保您的計算機的聲音是，太...

至於錯誤 - 我也有類似的問題，我的應用程序，它越來越不顧錯誤的相似的轉換，是沒有任何實際問題。經驗法則是，如果它在設備上工作，那麼你很好。
