暂时用的比较多的就这两个，用到其他的 再来更新！！
最近又用到了下载，索性 上传下载都研究了一下 ，补充进来
补充试用AFN3.0下载方法
1 /**
2 * AFN3.0 下载
3 */
4 - (void)downLoad{
5
6 //1.创建管理者对象
7 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
8 //2.确定请求的URL地址
9 NSURL *url = [NSURL URLWithString:@""];
10
11 //3.创建请求对象
12 NSURLRequest *request = [NSURLRequest requestWithURL:url];
13
14 //下载任务
15 NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {
16 //打印下下载进度
17 WKNSLog(@"%lf",1.0 * downloadProgress.completedUnitCount / downloadProgress.totalUnitCount);
18
19 } destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {
20 //下载地址
21 WKNSLog(@"默认下载地址:%@",targetPath);
22
23 //设置下载路径，通过沙盒获取缓存地址，最后返回NSURL对象
24 NSString *filePath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject];
25 return [NSURL URLWithString:filePath];
26
27
28 } completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) {
29
30 //下载完成调用的方法
31 WKNSLog(@"下载完成：");
32 WKNSLog(@"%@--%@",response,filePath);
33
34 }];
35
36 //开始启动任务
37 [task resume];
38
39 }
AFN3.0 上传
