1 使用cocoa pod引入AFNetworking，#imoport<AFNetworking/AFNetworking.h>
2 使用方法
（1）get请求
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];[manager ^(AFHTTPRequestOperation *operation, id responseObject) {NSLog(@"JSON: %@", responseObject);} failure:^(AFHTTPRequestOperation *operation, NSError *error) {NSLog(@"Error: %@", error);}];
（2）post请求
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];NSDictionary *parameters = @{@"foo": @"bar"};[manager parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {NSLog(@"JSON: %@", responseObject);} failure:^(AFHTTPRequestOperation *operation, NSError *error) {NSLog(@"Error: %@", error);}];
（3）图片上传
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];NSDictionary *parameters = @{@"foo": @"bar"};file://path/to/image.png"];[manager parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {[formData ];} success:^(AFHTTPRequestOperation *operation, id responseObject) {NSLog(@"Success: %@", responseObject);} failure:^(AFHTTPRequestOperation *operation, NSError *error) {NSLog(@"Error: %@", error);}];
（4）文件下载
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];"];NSURLRequest *request = [NSURLRequest requestWithURL:URL];^NSURL *(NSURL *targetPath, NSURLResponse *response) {];return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {NSLog(@"File downloaded to: %@", filePath);}];[downloadTask resume];
（5）创建上传任务
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];"];NSURLRequest *request = [NSURLRequest requestWithURL:URL];file://path/to/image.png"];^(NSURLResponse *response, id responseObject, NSError *error) {if (error) {NSLog(@"Error: %@", error);} else {, response, responseObject);}}];[uploadTask resume];
（6）带进度的任务上传
^(id<AFMultipartFormData> formData) {[formData file://path/to/image.jpgfilename.jpgimage/jpeg];} 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 {, response, responseObject);}}];[uploadTask resume];
