I need to use a custom NSView subclass to draw some content, but it isn't drawing as highlighted when the user hovers and it doesn't dismiss the NSMenu when the user clicks on it. Any ideas? Edit So using -drawRect: and [[self enclosingMenuItem] isHighlighted] I'm able to tell whether or not I need to draw the view as highlighted and a...
I figure I can achieve what I want by using NSCalendar and NSDateComponents, but that would run something like the following: Get "now" Create an NSDateComponents from "now". If "now" is pre-7am, then use today's date. If "now" is post-7am, use tomorrow's date. If today is the last day of the month, increase month, set day to 1. If i...

I've been building a framework and writing unit tests in GHUnit. One of my Framework's accessor methods returns an NSInteger. I assert the expected value in the tests like this: GHAssertEquals(1320, request.port, @"Port number should be 1320"); When running my tests with an AppKit UI based frontend this assertion passes. However, w...

What's the minimum implementation needed to make a custom NSView with an editable text area? I assume NSTextFieldCell can be used for this. I've succeeded in drawing the cell in the view (which is straightforward), but making it editable seems to require a more complicated coordination between the view and the cell. Is there sample code ...

My iPhone SDK and Objective-C learning is moving ahead quickly, thanks to several great books and online help (including this one). But I do have some basic questions due to what I already know that will be answered eventually, but I'd rather get a heads-up now if possible :) Are there equivalents for LayoutManagers in Cocoa Touch? Ar...

I'm building a program, and I'm quite confident using Objective-C, but I don't know how to programmatically download a file from the web and copy it on the hard drive. I started with : NSString url = @"http://spiritofpolo.com/images/logo.png"; NSData* data = [NSData dataWithContentsOfURL:[NSURL URLWithString:url]]; But then I don't kn...
Ok, so I'm pretty new to Cocoa, especially Bindings, but here's what I'm trying to do. I've got a Core Data model consisting of two entities: Category and Item. Category has a to-many relationship to Item called children, and Item has a relationship to Category called parent. Item has two attributes that Category does not have: quantity...
I've been using NSURLConnection to do a HTTP post to establish the connection. I've also implemented the didReceiveData delegate to process incoming bytes as they become available. As incoming data comes in via didReceiveData, I add the NSData to a data buffer and try parsing the bytesteam if enough data has come in to complete a messa...

Another iPhone noob question. The app I'm building needs to show a shared custom UIToolbar for multiple views (and their subviews) within a UITabBarController framework. The contents of the custom toolbar are the same across all the views. I'd like to be able to design the custom toolbar as a xib and handle UI events from its own cont...
I got this code: GrooveOnDownload *dlg = [[GrooveOnDownload alloc] init]; NSURLDownload *dw = [[NSURLDownload alloc] initWithRequest:request delegate:dlg]; It starts the download in a delegate class with outlets for UI controls. But for some reason controls don't respond to direct messages from the delegate. //Header of the delegate...
