声音与AVAudioPlayer玩 [英] Sound not playing with AVAudioPlayer

问题描述

我搜索，我相信我的问题是非常独特的。我知道使用AVAudioPlayer当模拟器5.1错误，这不是我的问题。我正在一个5.1的iOS设备上。

I've searched and I believe my problem is quite unique. I'm aware of the Simulator 5.1 bug when using AVAudioPlayer which isn't my problem. I'm running on a iOS 5.1 device.

下面是我的头文件：

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

-(IBAction)pushBell;

@end

和我的执行文件：

#import "BellViewController.h"

@interface BellViewController ()

@end

@implementation BellViewController

-(IBAction)pushBell {

    NSString *soundPath =[[NSBundle mainBundle] pathForResource:@"bell1" ofType:@"caf"];
    NSURL *soundURL = [NSURL fileURLWithPath:soundPath];
    NSError *error;

    AVAudioPlayer *theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:&error];
    [theAudio setDelegate:self];
    [theAudio setNumberOfLoops:0];
    [theAudio play];

}

@end

和我有一个按钮在我的.xib用于播放文件。

And I have a button in my .xib that plays the file.

的为了确保我正确地引用我的音频文件，我故意输入一个错误的文件名，确实是我得到了一个例外。为了确保该文件是可玩的，我把它寄给自己，发挥其在设备上。的

当我点击按钮，我听不见。有没有错误。我不知道什么是错的。

When I tap the button I hear nothing. There are no errors. I don't know what is wrong.

推荐答案

解决。

1：检查您的文件已在构建阶段被添加到复制包资源。

1.- Check if your file has been added to "Copy Bundle Resources" in Build Phases.

2：ViewController.m

2.- ViewController.m

#import <AVFoundation/AVAudioPlayer.h>

@interface ViewController ()
@property (nonatomic, strong) AVAudioPlayer *theAudio;
- (IBAction)pushBell;
@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSString *soundPath =[[NSBundle mainBundle] pathForResource:@"beep-beep" ofType:@"caf"];
    NSURL *soundURL = [NSURL fileURLWithPath:soundPath];

    NSError *error = nil;
    self.theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:&error];
}

- (IBAction)pushBell {
    [self.theAudio play];
}

3 .-的IBAction为连接到您在Interface Builder按钮。

3.- Connect the IBAction to your button in Interface Builder.
