Question

Generating a UIWebView with on-board resources is easy enough with the following code.

NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
[webView loadHTMLString:htmlString baseURL:baseURL];

However, what I need to do is move one step past simply having pre-generated data on the device, to actually downloading the data from a server to store locally. A lot of that I can handle myself with a reasonable degree of ease, but the question becomes: ‘what archive formats does IOS natively support?’

I know there are add-ons that let me support ZIP or PKZip, but if possible it would be preferable to restrict to Apple’s built-in tools.

Answer 1

If we interpret “archive” generously, as a way to store heterogeneous data in a single file without necessarily compressing it, then you could consider property lists and SQLite databases as archive formats. And, yes, the word “archive” is sometimes used that way, as in .tar format.
