我只是在音频文件播放完毕后尝试做某事,但似乎没有用。
在我的.h文件中,我有这个:
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
#import <AVFoundation/AVFoundation.h>
#import <CoreAudio/CoreAudioTypes.h>
@interface soundViewController : UIViewController
<AVAudioPlayerDelegate>
{
//various outlets
}
@property (strong, nonatomic) AVAudioPlayer *audioPlayer;
@end
在.m文件中我得到了:
#import "soundViewController.h"
@interface soundViewController ()
@end
@implementation soundViewController
@synthesize audioPlayer;
方法是:
- (void) playWord{
Word *currentWord = [[Word alloc]init];
currentWord = [testWords objectAtIndex:wordNum-1];
NSString *item = [currentWord word];
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/%@.mp3", [[NSBundle mainBundle] resourcePath], item]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = 0;
if (audioPlayer == nil){
NSLog(@"error in audioPlayer");
}
else{
[audioPlayer play];
NSLog(@"Playing word");
}
}
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag{
if (flag==YES){
NSLog(@"Finished!");
}
}
所以......一切都在游泳(除了声音文件以大写字母开头不起作用的事实),但是为什么声音结束时我没有看到“完成”的日志信息?
感谢您的帮助, 的Morten
答案 0 :(得分:2)
实际上,实际需要设置播放器的委托,例如:
audioPlayer.delegate = self;
希望这有帮助!
