我将歌曲放入表格中,我希望当第一首歌曲结束时在表格 View 中播放下一首歌曲..>>
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if let audio=NSBundle.mainBundle().pathForResource( elmp3[indexPath.row] , ofType: "mp3")
{
let url=NSURL (fileURLWithPath: audio)
do {
player = try AVAudioPlayer (contentsOfURL: url)
}
catch{"erorr"}
当你在同一 View 中播放cel歌曲时按下
这是数组歌曲
var elmp3 = ["001","002","003","004","005","006","007","008","009","010","011","012","013","014","015","016","017","018","019","020","021","022","023","024","025","026","027","028","029"]
最佳答案
- 为 selectedIndex 创建一个实例变量。
- 在 didSelectRowAtIndexpath: 方法中将 selectedIndex 更新为 indexPath.row。
- 实现 AVAudioPlayerDelegate 方法并为 AVAudioPlayer 实例设置委托(delegate)。
- 并在 audioPlayerDidFinishPlaying: 回调方法中,增加 selectedIndex 并播放列表中的下一个音频。
步骤如下:
1.
var selectedIndex:Int = 0
2.
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
//Set selected index
self.selectedIndex = indexPath.row
//get audio file URL at index
if let audio=NSBundle.mainBundle().pathForResource( elmp3[self.selectedIndex] , ofType: "mp3")
{
let url=NSURL (fileURLWithPath: audio)
do {
player = try AVAudioPlayer (contentsOfURL: url)
//Set delegate for AVAudioPlayer
player.delegate = self
}
catch{"error"}
}
3。
class AudioPlayerController:UIViewController, AVAudioPlayerDelegate{
func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer,
successfully flag: Bool){
if flag == true && self.selectedIndex < elmp3.count{
//Increment current index
++ self.selectedIndex
//Load audio at current index and play
if let audio=NSBundle.mainBundle().pathForResource( elmp3[self.selectedIndex] , ofType: "mp3")
{
let url=NSURL (fileURLWithPath: audio)
do {
player = try AVAudioPlayer (contentsOfURL: url)
player.delegate = self
}
catch{"error"}
}
}
}
