Question

我的应用程序在模拟器中完美打开，但是当我按下按钮进行播放时，没有声音播放。按钮似乎被按下，但没有播放音频。是我的代码或模拟器的问题吗？

这是我的ViewController.h

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>

@interface ViewController : UIViewController <AVAudioPlayerDelegate> {

}

- (IBAction)Whaddup;
- (IBAction)Speak;
- (IBAction)Hail;

@end

和我的ViewController.m

#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>

@interface ViewController ()

@end

@implementation ViewController




- (IBAction)Whaddup {
    NSString *path = [[NSBundle mainBundle] pathForResource:@"Whaddup" ofType:@"wav"];
    AVAudioPlayer *theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
    [theAudio play];
}

- (IBAction)Hail {
    NSString *path = [[NSBundle mainBundle] pathForResource:@"Hail" ofType:@"wav"];
    AVAudioPlayer *theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
    [theAudio play];
}

- (IBAction)Speak {
    NSString *path = [[NSBundle mainBundle] pathForResource:@"Speak" ofType:@"wav"];
    AVAudioPlayer *theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
    [theAudio play];
}




- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

有没有人知道为什么这不起作用？我将我的三个按钮与我的急救人员联系在一起，每个按钮使用“Touch Up Inside”。

尝试执行以下操作：您在项目中创建一个名为“Resources”的文件夹，并添加文件音乐“test.mp3”，例如：并在.h文件中：

#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
@property(retain,nonatomic) AVAudioPlayer * audioPlayer;// you add this variable

和.m文件

@synthesize audioPlayer;
-(void) readMP3{
    if (![audioPlayer isPlaying]) {
        NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/%@", [[NSBundle mainBundle] resourcePath],@"test.mp3"]];
        NSError *error;
        audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
        audioPlayer.numberOfLoops = 0;
        [audioPlayer play];
    }
}

和

-(void) stopReading{
[audioPlayer stop];
}

我希望能帮到你

音频不在iOS模拟器中播放？
