How to limit size of string in stringWithContentsOfURL:encoding:error:?

I do not see any answer on similar question regarding limiting size of read string from URL. A user can point by mistake on URL bringing several gigabytes 开发者_StackOverflow中文版of data which obviously will bring down my iPhone application. I want to limit size to 100Kb, is there any way to do that using the standard method?

In short, no, because the method you're referring to is pretty much a convenience method. If you want to check the size of the request prior to making it, you might as well use ASIHTTPRequest or even just NSURLConnection.

Specifically with ASIHTTPRequest, you'll get a delegate callback when the HTTP headers are received, so you'll know the size. Then, if the size is 100KB+, you can just cancel the request.
