我遇到AVAudioPlayer类的奇怪问题。 每次尝试访问它的一个属性时,它们都是空的。AVAudioPlayer isPlaying始终返回null
// Get the file path to the song to play.
NSString *filePath = [[[NSBundle mainBundle] pathForResource:pSound.fileName
ofType:pSound.fileType] retain];
// Convert the file path to a URL.
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
NSError* err;
//Initialize the AVAudioPlayer
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&err];
if(err){
NSLog(@"Initializing failed with reason: %@", [err localizedDescription]);
}
else{
[self.audioPlayer setDelegate:self];
[self.audioPlayer prepareToPlay];
self.playCount = self.playCount + 1;
NSLog(@"%@", [self.audioPlayer isPlaying]); //this displays null; also if I call it at a later time
};
[filePath release];
[fileURL release];
任何想法?
编辑:奇怪的是当我保存IsPlaying模块为BOOL和打印布尔我得到一个值...
你有没有设法解决这个问题?我有同样的问题,无法弄清楚。 – Neeku 2013-11-23 15:59:07
