我正在尝试制作一个简单的音频板应用程序，我正在关注 AVFoundationPlayer 上的 Apple 文档，但我一直收到此错误（“NSBundle”没有可见的@interface 声明选择器“pathForRescourc:ofType:”）并且我已经搜索过一个小时，没有结果。
我的 .h 文件
#import <UIKit/UIKit.h>
#import <AVFoundation/AVAudioPlayer.h>
@interface ViewController : UIViewController <AVAudioPlayerDelegate> {
}
//actions
-(IBAction)playSound1;
-(IBAction)playSound2;
-(IBAction)playSound3;
-(IBAction)playSound4;
@property (nonatomic, strong) AVAudioPlayer *player;
@结尾
我的 .m 文件
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize player;
- (void)viewDidLoad
{
NSString *soundFilePath1 =
[[NSBundle mainBundle] pathForRescource: @"trumpet"
ofType: @"mp3"];
NSURL *fileURL1 = [[NSURL alloc] initFileURLWithPath: soundFilePath1];
AVAudioPlayer *newPlayer =
[[AVAudioPlayer alloc] initWithContentsOfURL:fileURL1 error:nil];
[fileURL1 release];
self.player= newPlayer;
[newPlayer release];
[player prepareToPlay];
[player setDelegate: self];
[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.
}
@结尾
如果我可以提供任何其他详细信息，我将很乐意提供帮助并感谢您的阅读。
