AFNetwork を使用して複数のファイルをダウンロードしたいのですが、これを実装する方法がわかりません。ご覧のとおり、操作配列を作成し、それに 3 つのタスクを追加します。
NSMutableArray *operations = [NSMutableArray array];
NSArray *requestArray = @[ @"...task1.zip", @"task2.zip", @"task3.zip" ];
for (int i = 0; i < 3; i++) {
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:[requestArray objectAtIndex:i]]];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:[[requestArray objectAtIndex:i] lastPathComponent]];
operation.outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"Successfully downloaded file to %@", path);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
[operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
NSLog(@"Operation%i: bytesRead: %d", i, bytesRead);
NSLog(@"Operation%i: bytesRead: %lld", i, totalBytesRead);
NSLog(@"Operation%i: bytesRead: %lld", i, totalBytesExpectedToRead);
}];
[operations addObject:operation];
}
そして、私は何をすべきですか?私は次のことをしますが、何も起こりません
AFHTTPClient *requestHandler = [[AFHTTPClient alloc] init];
[requestHandler enqueueBatchOfHTTPRequestOperations:operations progressBlock:^(NSUInteger numberOfCompletedOperations, NSUInteger totalNumberOfOperations) {
} completionBlock:^(NSArray *operations) {
}];
この問題についてのアイデアはありますか?
