A download manager for iOS. Actually, all that you need to download files without any external library.

Goals:

  • download of a sequence of files
  • ease of download of a sequence of files with the same base URL address
  • create locally the folders hierarchy mapping the remote path (splitting the URL) or save all files in the same directory
  • in case of files the with same base URL address, its components are not used in the folders creation
  • downloads happen in background and in a serial fashion
  • ability of canceling downloads that are not started yet

If you’d like to include this component as a pod using CocoaPods, just add the following line to your Podfile: pod "ADBDownloadManager"

Try out the included demo project or just run pod try ADBDownloadManager to give it a try.

Simple usage:

  • copy ADBDownloadManager class into your project
  • import ADBDownloadManager.h in your class
  • create the DownloadManager
NSString *documentsDirectory = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
// without base URL
self.downloadManager = [[ADBDownloadManager alloc] initWithLocalPathFolder:documentsDirectory];
// or with base URL
self.downloadManager = [[ADBDownloadManager alloc] initWithBaseRemoteURL:@"http://www.myservice.com/"
                                                         localPathFolder:documentsDirectory];
  • optionally set behaviours
self.downloadManager.forceDownoad = YES; // overwrites files, default is NO
self.downloadManager.createFoldersHierarchy = NO; // avoid the creation of the folders hierarchy, default is YES
  • set the delegate and the dataSource
self.downloadManager.delegate = self;
self.downloadManager.dataSource = self;

[self.downloadManager start];
  • implement the ADBDownloadManagerDataSource protocol
#pragma mark - ADBDownloadManagerDataSource

- (NSUInteger)numberOfFilesToDownloadForDownloadManager:(ADBDownloadManager *)manager { ... }

- (NSString *)downloadManager:(ADBDownloadManager *)manager
 pathForFileToDownloadAtIndex:(NSUInteger)index { ... }
  • implement the ADBDownloadManagerDelegate protocol
#pragma mark - ADBDownloadManagerDataSource

- (void)downloadManager:(ADBDownloadManager *)manager
 didDownloadFileAtIndex:(NSUInteger)index
          fromRemoteURL:(NSString *)remoteURL
            toLocalPath:(NSString *)localPath
                  bytes:(NSUInteger)bytes { ... }

- (void)downloadManager:(ADBDownloadManager *)manager
     didFailFileAtIndex:(NSUInteger)index
          fromRemoteURL:(NSString *)remoteURL
            toLocalPath:(NSString *)localPath
                  error:(NSError *)error { ... }

- (void)downloadManagerDidCompleteAllDownloads:(ADBDownloadManager *)manager
                                    failedURLs:(NSArray *)failedURLs
                                    totalBytes:(NSUInteger)totalBytes { ... }

- (void)downloadManagerWillStart:(ADBDownloadManager *)manager { ... }

- (void)downloadManagerDidStop:(ADBDownloadManager *)manager { ... }
  • start the manager
[self.downloadManager start];
  • stop it later if you need to
[self.downloadManager stop];

There you go.
