在IOS開發中經常會用到系統相冊，相機，音視頻等功能。每次都寫比較麻煩，自己封裝了一個工具類，實現一句話調用系統相冊，相機，音視頻等功能。方便以后項目的開發。
//加載圖片
SystemTool.shareTool.choosePicture(self, editor: false) { (image) in
button.setImage(image, for: UIControlState.normal)
}
//加載視頻
//http://baobab.wdjcdn.com/14562919706254.mp4
SystemTool.playVideoWithPath(video: "apple.mp4", viewController: self)
//加載音樂
SystemTool.playAudioWithPath(sound: "song.mp3")
//停止音樂
SystemTool.stopAudioPlayer()
