如何使用 ASIHTTPRequest 跟踪上传/下载进度 [英] How to Using ASIHTTPRequest to tracking Upload/Download progress

问题描述

我有一个问题是使用 ASIHTTPRequest 来跟踪上传/下载进度

I got some question is using ASIHTTPRequest to tracking Upload/Download progress

这是来自 ASIHTTPRequest 网站的示例

This is the sample from ASIHTTPRequest website

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadProgressDelegate:myProgressIndicator];
[request startSynchronous];
NSLog(@"Max: %f, Value: %f", [myProgressIndicator maxValue],[myProgressIndicator doubleValue]

它说:myProgressIndicator 是一个 NSProgressIndicator.

It says :myProgressIndicator is an NSProgressIndicator.

但看起来 Apple 已弃用 NSProgressIndicator

But it looks like Apple deprecated NSProgressIndicator

检查这里

那么……我怎么知道上传/下载进度???

So ... how can I know the Upload/Download progress ???

还有一个问题是...如果上传/下载在任务完成之前终止

Also another question is ...if the Upload/Download was terminated before the task finish

如何让上传/下载任务从停止点(断点?)开始?

How can I let the Upload/Download task continues start from the stop point(break point?) ?

非常感谢~

推荐答案

正如文档所说，在 iphone/ipad 的情况下，delegate 也可以是 UIProgressView:

As the documentation says, the delegate can also be an UIProgressView in case of iphone/ipad:

每个 ASIHTTPRequest 有两个委托可用于跟踪进度- downloadProgressDelegate(用于下载)和uploadProgressDelegate(用于上传).

Each ASIHTTPRequest has two delegates that can be used for tracking progress - downloadProgressDelegate (for downloads) and uploadProgressDelegate (for uploads).

进度委托可以是NSProgressIndicators (Mac OS X) 或UIProgressViews (iPhone).ASIHTTPRequest 会自动迎合差异这两个类的行为.如果你想要，您也可以使用自定义类作为进度委托，只要它响应 setProgress:.

Progress delegates can be NSProgressIndicators (Mac OS X) or UIProgressViews (iPhone). ASIHTTPRequest will automatically cater for the differences in the behaviour of these two classes. If you want, you can also use a custom class as a progress delegate, as long as it responds to setProgress:.

• 如果您正在表演单曲请求，您设置上传和/或下载进度委托请求
• 如果您正在执行多个队列中的请求，并且您想要跟踪所有人的整体进度队列中的请求，使用ASINetworkQueue 并设置进度队列的委托
• 如果你想同时做这两件事，这也是可能的(从 v0.97 开始)
