file - 从Plist播放音频文件

Question

在我的Controller.h文件中...我列出了我正在使用的NSDictionary以及要提取的项目。但是我在识别音频记录变量时遇到问题...

@property (nonatomic, retain) NSDictionary *dataForCurrentLevel;
@property (nonatomic, retain) IBOutlet UILabel *Name;
@property (nonatomic, retain) IBOutlet UILabel *Author;
@property (nonatomic, retain) IBOutlet UILabel *Time;
@property (nonatomic, retain) NSString *Recording;

在我的Controller.m文件中...

- (void)viewDidLoad 
{     

// Configure the user interface by extracting the data from the dictionary
     Name.text = [dataForCurrentLevel valueForKey:@"Name"];
     Author.text = [dataForCurrentLevel valueForKey:@"Author"];
     Time.text = [dataForCurrentLevel valueForKey:@"Time"];     

//以上行工作正常。构建引入并在我的新 View Controller 中显示数据，没有问题。但是，我无法提取字典项随附的音频m4a文件。使用以下代码，我可以播放一个特定的音频文件...但是如何更改以下代码，以在当前表级别拉入plist词典中列出的音频文件？仅供引用，音频文件中列出了对象键:“录制”类型:“字符串”和变量值，例如:“buzz.4ma”

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"buzz" ofType:@"m4a"]];
self.myPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error:nil];

//如何获取pathForResource以在plist词典中选择可变音频文件？

我更改了plist词典，发现解决方案是:
NSDictionary * dict = [NSDictionary dictionaryWithContentsOfFile:plistPath];
dict = [dict objectForKey:@“Root”];

for (int i = 0; i < numberOfSongs; i++){

    NSDictionary *songInfo = [dict objectForKey:[NSString stringWithFormat:@"Item%d",i]];
