Как скачать и сохранить аудио с сервера?

#ios #objective_c #аудио

Хочу сделать музыкальный проигрыватель. Но не знаю как можно скачать файл с облака
и сохранить на устройстве. Помогите пожалуйста с решением этой проблемы.

код:

AudioPlayer.m

#import "AudioPlayer.h"

@implementation AudioPlayer


- (void)initPlayer:(NSString*) audioFile fileExtension:(NSString*)fileExtension
{
NSURL *audioFileLocationURL = [[NSBundle mainBundle] URLForResource:audioFile withExtension:fileExtension];
NSError *error;
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioFileLocationURL
error:&error];
}


- (void)playAudio {
[self.audioPlayer play];
}


- (void)pauseAudio {
[self.audioPlayer pause];
}


- (BOOL)isPlaying {
return [self.audioPlayer isPlaying];
 }


-(NSString*)timeFormat:(float)value{

float minutes = floor(lroundf(value)/60);
float seconds = lroundf(value) - (minutes * 60);

int roundedSeconds = lroundf(seconds);
int roundedMinutes = lroundf(minutes);

NSString *time = [[NSString alloc]
                  initWithFormat:@"%d:%02d",
                  roundedMinutes, roundedSeconds];
return time;
 }

 - (void)setCurrentAudioTime:(float)value {
[self.audioPlayer setCurrentTime:value];
 }


 - (NSTimeInterval)getCurrentAudioTime {
return [self.audioPlayer currentTime];
 }


 - (float)getAudioDuration {
return [self.audioPlayer duration];
 }


 @end

Ну допустим скачать можно вот так

NSString *stringURL = @"http://www.cloud.com/music.mp3";
NSURL  *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,
YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];  

    NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"music.mp3"];
    [urlData writeToFile:filePath atomically:YES];
}


Загрузить, и начать играть

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,
YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"music.mp3"];

self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:filePath]
error:nil];
[self.player play];
