{
   audio =    
   (
       {
           type = pronunciation;
           url = "/v2/dictionaries/assets/ldoce/gb_pron/abate0205.mp3";
       }

知道了， 执行以下操作

NSDictionary *dictResult = [JSONRepsponse objectForKey:@"result"];
NSDictionary *dictPronunciations = [dictResult valueForKey:@"pronunciations"];
NSDictionary *dictAudio = [dictPronunciations valueForKey:@"audio"];
NSString *strMp3Path = [dictAudio valueForKey:@"url"];
NSString *commonUrl = @"https://api.pearson.com";
NSString *strUrl = [commonUrl stringByAppendingString:strMp3Path];
NSURL *url =  [NSURL URLWithString:[strUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSData *dataMp3 = [NSData dataWithURL : url];

您可以使用此数据在 AvAudio Player 中播放 Mp3
