Hi all, I know I'm probably going to be berated for not properly reading the HIG or some documentation, but after going through several training videos and building a number of small projects on the iPhone, I'm now trying to put stuff together on the iPad and, well, my brain hurts. I understood the idea on the iPhone that one view = on...

I've been trying to make this work for some time now, but I think I need someone on the outside to see what I'm doing wrong. In my app, I'm getting a JSON value from a web server, and parsing it into my table view. responseData = [NSData dataWithContentsOfURL: [NSURL URLWithString: @"http://myserver/json"]]; NSString *responseString = [...

I'm trying to implement the Strategy pattern using Core Data and Objective C. To simplify, I have, say, a multilingual Text entity, which has several attributes, such as a Date for last saved, and a NSSString for author etc etc. I want to add a reference to a Language entity, which could be one of several subclasses, such as French, Ita...
By default, double-clicking triggers renaming in NSTableView. How can I let double-clicking instead trigger my own custom code (such as opening the double-clicked file)? And also: How can I let the renaming be like in Finder, where you first single click, and then click again and quickly move the mouse pointer away? That is how renamin...

I'd like to start creating a few apps for the mac and iPhone for personal interest, but I'm not sure which is the better place to start. Both seem to have a fair bit in common: objective-c, cocoa, xcode, etc. so I would assume that there are a lot of transferable skills. My question is: which is the easier starting point? Creating a sm...

I'm pretty sure that I'm going to feel really dumb when I remember how to do this, but here it is: I have two classes A and B. A has an object of type B, B has an object of type A. This is not that unusual. The problem is that A.h needs to import B.h and vice versa. However, one of them has to happen first, and when it does, the use of ...
Is it possible for an objective c application to run python files and read their data, ect? If so, can someone post code? or lead me in the right direction? Thanks, Elijah ...
Hey guys, I was wondering if objective C does any check to see if a pointer to an object is nil before calling the function. For example, say I have a myObject* ptr; and initialize ptr = nil; and call [self myFunction:ptr]; where myFunction is my own function and does no check to see if the object is nil. I heard somewhere th...
