iOS ASIHttpRequest 和 AFNetWorking 实时监测下载进度

本文主要是介绍iOS ASIHttpRequest 和 AFNetWorking 实时监测下载进度，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

ASIHttpRequset

遵守< ASIProgressDelegate>协议

@property (nonatomic, retain) ASIHTTPRequest *request;

// 下载路径

self.request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:@"http://dlsw.baidu.com/sw-search-sp/soft/2a/25677/QQ_V4.0.2.1427684136.dmg"]];

// 给下载任务设置路径和代理

[_request setDownloadDestinationPath:path];

[_request setDownloadProgressDelegate:self];

_begainDownloadTimer = [NSTimer scheduledTimerWithTimeInterval:3.f target:self selector:@selector(begainDownloadTimerAction) userInfo:nil repeats:NO];

// 开始下载

- (void)begainDownloadTimerAction

{

[_request startAsynchronous];

}

// 实时下载数据在这个代理方法里通知

- (void)request:(ASIHTTPRequest *)request didReceiveBytes:(long long)bytes

{

}

AFNetWorking

@property (nonatomic, retain) AFHTTPRequestOperation *operation;

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://dlsw.baidu.com/sw-search-sp/soft/2a/25677/QQ_V4.0.2.1427684136.dmg"]];

//下载附件

self.operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

_operation.outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO];

[_operation start];

//下载进度控制

__block TestWifiSpeedVC *weakSelf = self;

[_operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {

}
