[ANN] CoreParse (Version n+1)

Hi All, A while ago I showed you all my parsing library 'CoreParse', and got some really useful feedback. Today, I'd like to show you what's changed since then! • Easier processing of syntax trees into your data structures. In earlier versions of CoreParse you had to use a parser delegate t

Hi, I am getting occasional reports of an exception from users of my software, but they are not able to reproduce it, and nor am I. I have a sheet which has an NSCollectionView on it and a couple of buttons and a slider. The NIB also instantiates an array controller which is used as the content

NSURLRequests and Firewalls

I just found out why some JSON parsing was failing, the data returned from the NSURLRequest was the HTML for our firewall authentication page. Is there an established practice or set of documents on the iOS Dev Lib that shows how to handle this? I scanned the sample code and found nothing. Se

Convert PDF CGContextRef to NSView for hi-res printing

Hi, I'm stuck on a problem on how to print high resolution graphs on Mac OS X, by using the wonderful CorePlot (1) framework. I've asked on the Coreplot mailing list but no answer...maybe it's too obvious that I don't see the tree in the forest: My method produces a CGContextRef (with CGPDFCont

I think generally a firewall ought to return an http status code of 302 redirected which you could probably key off for a login handler. Time Dwarf, Roaring Guy On 2012-03-05, at 11:21 AM, Alex Zavatone wrote: > I just found out why some JSON parsing was failing, the data returned from > the

Yeah, at this facility, I get a web page asking to log in with auth parameters, so it's going to be interesting. Using the simulator, even if I enter the auth parameters in Safari, I'll run the app again from Xcode and get the same HTML telling me that permission was denied and asking for auth

Re: Unclear on -initWithBytesNoCopy:

Perhaps the only 'correct' solution to this problem is to fall back to the CFString level, where you can pass a custom CFAllocator to e.g. CFStringCreateWithBytesNoCopy(). That way the lifetime is effectively managed by the CFString, so it should behave correctly in all cases. 'course, the imp

Re: How are views supposed to reload after being nillified by memory warnings?

Well, at any rate, I have no such subview property. I've also found that among my series of modal presentations, there's a view that's displayed modally, whose user interaction works just fine, but whose viewWillAppear and viewWillDisappear methods are never called. As far as I know, it could be

Interesting. If that's the case, then the documentation for that method is correct, the caller is responsible for freeing the returned object. I will file a bug report. Thanks. - Original Message - From: Gus Mueller To: Cocoa mailing list Cc: Sent: Monday, March 5, 2012 1:44 PM Sub
