本範例為點擊按鈕播放影片,步驟如下
1. 建立專案後加入MediaPlayer.framework
2. storyboard加入一顆按鈕來觸發影片播放
3. 將要播放的影片網址複製

本範例為點擊按鈕播放影片,步驟如下
1. 建立專案後加入MediaPlayer.framework
2. storyboard加入一顆按鈕來觸發影片播放
3. 將要播放的影片copy進專案中

此範例為點擊按鈕觸發點擊按扭播放音樂,
順帶一提此程式需要在實機上執行才有效過, 模擬器則無法測試
Step1. 創建一個新專案, 加入一顆按鈕, 點擊可產生播放音樂, 將音樂檔案加入專案, 並建立Button與程式之關聯性
Step2. 加入AVFoundation.framework, 並#import <AVFoundation/AVFoundation.h>
