一、文件下載
1.創建下載
//1.創建會話管理者
AFHTTPSessionManager *manager =[AFHTTPSessionManager manager];
NSURL *url = [NSURL URLWithString:@"http://120.25.226.186:32812/resources/videos/minion_01.mp4"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
//2.下載文件
/*
第一個參數:請求對象
第二個參數:progress 進度回調 downloadProgress
第三個參數:destination 回調(目標位置)
有返回值
targetPath:臨時文件路徑
response:響應頭信息
第四個參數:completionHandler 下載完成之後的回調
filePath:最終的文件路徑
*/
NSURLSessionDownloadTask *download = [manager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {
//監聽下載進度
//completedUnitCount 已經下載的數據大小
//totalUnitCount 文件數據的中大小
NSLog(@"%f",1.0 *downloadProgress.completedUnitCount / downloadProgress.totalUnitCount);
} destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {
NSString *fullPath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:response.suggestedFilename];

NSLog(@"fullPath:%@",fullPath);
return [NSURL fileURLWithPath:fullPath];
} completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) {
NSLog(@"%@",filePath);
}];
//3.執行Task
[download resume];
2.簡單下載工具類
+(void)get:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
{
//1.獲得請求管理者

}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if (failure) {
failure(error);
}
}];
}
+(NSURLSessionDataTask *)post:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
{
//1.獲得請求管理者
AFHTTPSessionManager *mgr = [AFHTTPSessionManager manager];
NSURLSessionDataTask *dataTask = [mgr POST:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {

五、網絡監測
