avplayer沒有播放該網址

Question

我正在使用avplayer播放音頻網址，但它無法正常工作，我不知道我錯在哪里

NSString *radioURL = @"https://www.example.com";

radioPlayer = [AVPlayer playerWithURL:[NSURL URLWithString:radioURL]] ;
// [radioPlayer seekToTime:kCMTimeZero];
NSLog(@"radio player %@",radioPlayer.currentItem);
[radioPlayer play];

任何幫助，將不勝感激。

我強烈推薦下面的代碼來播放無線電流：請看看AVPlayer_Class

 -(void)Play{
        NSString *radioURL = @"https://www.example.com"; //this url must valid 
        AVPlayer *player = [[AVPlayer alloc]initWithURL:[NSURL URLWithString:radioURL]];
        self.songPlayer = player;    //self.songPlayer is a globle object of avplayer
        [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(playerItemDidReachEnd:)
                                                     name:AVPlayerItemDidPlayToEndTimeNotification
                                                   object:[songPlayer currentItem]];
        [self.songPlayer addObserver:self forKeyPath:@"status" options:0 context:nil];
}


- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {

        if (object == songPlayer && [keyPath isEqualToString:@"status"]) {
            if (songPlayer.status == AVPlayerStatusFailed) {
                NSLog(@"AVPlayer Failed");

            } else if (songPlayer.status == AVPlayerStatusReadyToPlay) {
                NSLog(@"AVPlayerStatusReadyToPlay");
                [self.songPlayer play];


            } else if (songPlayer.status == AVPlayerItemStatusUnknown) {
                NSLog(@"AVPlayer Unknown");

            }
        }
    }

- (void)playerItemDidReachEnd:(NSNotification *)notification {

     //  code here to play next sound file

    }

我有同樣的問題，只是意識到我沒有保留播放器（使用ARC）！ 所以它被取消分配並在開始后立即停止播放。

您需要確保擁有強大的屬性radioPlayer並使用self.radioPlayer而不是radioPlayer。

Answer 3

你做得很好，但你的方法需要在一個地方糾正。使用以下方法檢查：

NSURL *audioURL = [NSURL URLWithString:radioURL];
NSData *audioData = [NSData dataWithContentsOfURL:audioURL];
self.audioPlayer = [[AVAudioPlayer alloc] initWithData:audioData error:nil];
self.audioPlayer.numberOfLoops = -1;
self.audioPlayer.delegate = self;
[self.audioPlayer prepareToPlay];
self.audioPlayer.volume=1.0;
[self.audioPlayer autorelease];
[self.audioPlayer Play];

並為AVAudioPlayer添加適當的委托方法。

您是否忘記設置屬性App Transport Security Settings -> Allow Arbitrary Loads (Yes) ？

Answer 5

確保URL是AddingPercentEscapes 。

NSURL *audioURL = // Your Url;
NSString *encodedString = [@"Your Url" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *myURL = [[NSURL alloc] initWithString:encodedString]
AVPlayer *player = [AVPlayer playerWithURL:myURL];
[player prepareToPlay];
player play];
