本文介绍使用AFNetworking库在iOS应用中实现文件上传及下载的功能。通过具体代码示例展示了如何利用AFHTTPSessionManager进行文件上传并跟踪进度，同时演示了如何下载文件到指定路径并监控下载进度。

// ViewController.m

// AFN上传文件

// Created by 唐帅 on 16/7/3.

#import "ViewController.h"

#import "AFNetworking.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

}

- (IBAction)uploadFile:(id)sender {

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

NSString *urlstr = @"http://localhost/post/upload-m.php";

[manager POST:urlstr parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {

// 文件二进制

NSData *data = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"mm01.jpg" ofType:nil]];

// 拼接请求体

[formData appendPartWithFileData:data name:@"userfile[]" fileName:@"mmm01.jpg" mimeType:@"image/jpg"];

} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {

NSLog(@"%@",responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

NSLog(@"%@",error);

}];

}

- (IBAction)downloadFile:(id)sender {

//配置信息

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

//管理者

// AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:config];

//下载地址

NSString *urlstr = @"http://localhost/1.zip";

//请求

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlstr]];

NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {

NSLog(@"%f",downloadProgress.fractionCompleted);

} destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {

NSString *filePath = @"/Users/haoxu/Desktop/11/22.zip";

//这个一定不能错，错了就出不来了

return [NSURL fileURLWithPath:filePath];

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

// 文件最终保存的路径 : 从上面自动剪切过来的

NSLog(@"%@",filePath.path);

}] ;

// 开启下载任务

[downloadTask resume];

}

- (void)didReceiveMemoryWarning {

[super didReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}
