ios - 如何获得歌曲的实际持续时间，如“mm：ss”格式？

Question

assetURL = [item valueForProperty: MPMediaItemPropertyAssetURL];
NSLog(@"%@", assetURL); // asset url declares the song url and song path

AVURLAsset* audioAsset = [AVURLAsset URLAssetWithURL:assetURL options:nil]; // declare the audio asset url
CMTime audioDuration = audioAsset.duration; // get duration in cm time
double audioDurationSeconds = CMTimeGetSeconds(audioDuration); // convert audio duration in double 

但这是一个问题，因为我只在几秒钟内获得音频持续时间，但我需要歌曲持续时间的“MM：SS”格式。

请帮我。提前致谢。

Answer 1

NSUInteger audioDurationSeconds = (long)CMTimeGetSeconds(audioDuration);
NSUInteger minutes = floor(audioDurationSeconds % 3600 / 60);
NSUInteger seconds = floor(audioDurationSeconds % 3600 % 60);
NSString *time = [NSString stringWithFormat:@"%02ld:%02ld", minutes, seconds];
