最佳答案

//Your song id NSString *songID;

MPMediaPropertyPredicate *predicate = [MPMediaPropertyPredicate predicateWithValue:songID forProperty:MPMediaItemPropertyPersistentID];

MPMediaQuery *mySongQuery = [[MPMediaQuery alloc] init];
//finding songs for predicate
[mySongQuery addFilterPredicate: predicate];

//add songs to queue
[musicPlayer setQueueWithQuery:mySongQuery];

[musicPlayer play];
