今はみんなAFNetworkingを使うのが好きです。守る人がいます。公式文書を見てください。使用コードを簡単に羅列してください。
まずCocoaPodsを通じて(使ったことがないのはこの文章を見ます)AFNetworkingを下ろします。
Podfile

platform :ios, '7.0'

pod "AFNetworking", "~> 2.0"

方法1：GET要求

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"JSON: %@", responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"Error: %@", error);

}];

方法二：POSTリクエスト

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSDictionary *parameters = @{@"foo": @"bar"};

[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"JSON: %@", responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"Error: %@", error);

}];

方法3：POST Multi-Part Request

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSDictionary *parameters = @{@"foo": @"bar"};

NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];

[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

    [formData appendPartWithFileURL:filePath name:@"image" error:nil];

} success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"Success: %@", responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"Error: %@", error);

}];

方法四：ダウンロードファイルのタスクを作成します。

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];



NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];

NSURLRequest *request = [NSURLRequest requestWithURL:URL];



NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {

    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];

    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];

} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {

    NSLog(@"File downloaded to: %@", filePath);

}];

[downloadTask resume];

方法5：ファイルアップロードタスクを作成する

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];



NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];

NSURLRequest *request = [NSURLRequest requestWithURL:URL];



NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {

    if (error) {

        NSLog(@"Error: %@", error);

    } else {

        NSLog(@"Success: %@ %@", response, responseObject);

    }

}];

[uploadTask resume];

方法6：アップロードファイルのタスクを作成し、進捗を表示する

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

        [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];

    } error:nil];



AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSProgress *progress = nil;



NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {

    if (error) {

        NSLog(@"Error: %@", error);

    } else {

        NSLog(@"%@ %@", response, responseObject);

    }

}];

[uploadTask resume];

方法7：アップロードデータを作成するdataタスク

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];



NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];

NSURLRequest *request = [NSURLRequest requestWithURL:URL];



NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {

    if (error) {

        NSLog(@"Error: %@", error);

    } else {

        NSLog(@"%@ %@", response, responseObject);

    }

}];

[dataTask resume];

方法8：ネットワーク状態を取得する

[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));

}];

方法9：HTTP Manager Reachability

NSURL *baseURL = [NSURL URLWithString:@"http://example.com/"];

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];



NSOperationQueue *operationQueue = manager.operationQueue;

[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

    switch (status) {

        case AFNetworkReachabilityStatusReachableViaWWAN:

        case AFNetworkReachabilityStatusReachableViaWiFi:

            [operationQueue setSuspended:NO];

            break;

        case AFNetworkReachabilityStatusNotReachable:

        default:

            [operationQueue setSuspended:YES];

            break;

    }

}];



[manager.reachabilityManager startMonitoring];

方法10：AHTTPRequest OperationのGET要求

NSURL *URL = [NSURL URLWithString:@"http://example.com/resources/123.json"];

NSURLRequest *request = [NSURLRequest requestWithURL:URL];

AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];

op.responseSerializer = [AFJSONResponseSerializer serializer];

[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"JSON: %@", responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"Error: %@", error);

}];

[[NSOperationQueue mainQueue] addOperation:op];

方法11：Batch of Operations

NSMutableArray *mutableOperations = [NSMutableArray array];

for (NSURL *fileURL in filesToUpload) {

    NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

        [formData appendPartWithFileURL:fileURL name:@"images[]" error:nil];

    }];



    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];



    [mutableOperations addObject:operation];

}



NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:@[...] progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {

    NSLog(@"%lu of %lu complete", numberOfFinishedOperations, totalNumberOfOperations);

} completionBlock:^(NSArray *operations) {

    NSLog(@"All operations in batch complete");

}];

[[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO];

方法12：要求された情報を得る（私も使ったことがないので、あまり使わない）
Request Serialzation
Request serializers create requests from URL stings，encoding parameters as eigher a query string or HTTP body.

NSString *URLString = @"http://example.com";

NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};

Query String Parameter Ecoding

[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];



GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3

URL Form Parameter Ecoding

[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];



POST http://example.com/

Content-Type: application/x-www-form-urlencoded



foo=bar&baz[]=1&baz[]=2&baz[]=3

JSONパラメータEcoding

[[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];



POST http://example.com/

Content-Type: application/json



{"foo": "bar", "baz": [1,2,3]}

jquery体中contensts()を経験しました。
