Как скачать и сохранить аудио с сервера?

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

Ответ

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];
