Connecting to the Internet in a Mac Application

The last GUI programming I have done was with Visual Basic, which included objects like Winsock and Inet to easily connect to the internet and retrieve the source from webpages.

I just got started into XCode, and was wondering if there is a similar component. I see that there is a Webkit option in the Library, but I have no idea how to use it.

任何帮助，将不胜感激。

I want to simulate the browser as well as possible (including cookies, headers, etc). Is the Webkit approach better than the link you just gave me? Sorry I was no more clear in the OP.

看答案

Apple has two guides in the documentation you'll want to look at, URL Loading System 和 WebKit Objective-C Programming Guide。 You'll probably be most interested in the former if you want to request data from a web server behind the scenes, or the latter if you want to actually put a web browser control into your application. Both documents should explain the classes you'll use and the general process, but let me know if you have questions.

A lot of the core Cocoa data types like NSString, NSDate, and even NSArray and NSDictionary have methods for loading data from a URL like Heng-Cheong Leong mentioned, but they abstract away all the low level stuff and probably won't be suitable if you want to deal with HTTP headers.

redis中的hash扩容渐进式rehash过程

背景： redis字典（hash表）当数据越来越多的时候，就会发生扩容，也就是rehash 对比：java中的hashmap，当数据数量达到阈值的时候(0.75)，就会发生rehash，hash表长度变为原来的二倍，将原hash表数据全部重新计算hash地址，重新分配位置，达到rehash目的 redis中的hash表采用的是渐进式hash的方式： 1、redis字典（hash表）底层有...
