当AVAudioPlayer停止播放时,我想知道并更改UIImageView。我正在努力,但我还没想到这一点。有什么办法吗?我的代码在
之下 if ([[NSFileManager defaultManager] fileExistsAtPath:ttsOutWav]) {
audioPath1 = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:ttsOutWav] error:&error];
if (!error) {
[audioPath1 play];
NSLog(@"should be played");
}
else {
NSLog(@"Error in creating audio player:%@",[error description]);
}
}
else{NSLog(@"such file doesnt exist");}

我自己从未这样做过,但我希望您需要设置AVAudioPlayerDelegate
委托类并实现以下方法:
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player
successfully:(BOOL)flag
答案 1 :(得分:1)
使用此委托方法,以便此方法将回调,
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
}
以及解码时出错时的以下代理
- (void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error
{
}
