I found a Stack Overflow thread from a couple of years ago on this. Seems your best bets are GNUstep and Cocotron.

Eh, I'm not sure. I just have one tiny simple app in the Store under my own name, all my other iOS jobs have been consultancy.

They did specifically mention that devs with active apps on the store would be picked first, but for the rest it really was a first come first served affair. My guess is that there were enough active devs to fill the venues, so they applied the first principle to those as well. I reserved my place like five minutes after I got the invite.

e: I can understand how lots of people are pretty mad at getting rejected and I would have been too, because HOLY poo poo is it ever a treasure trove of knowledge. Really the sort of stuff you can't get from checking out poo poo on the web or reading Apple's doc, this looks like getting schooled at a WWDC-level.

I have a project set up in Xcode 4.1. The project builds and functions correctly on my development machine (MacBook Pro running Lion). But when I transfer my app to the machine we need to run it on, it bounces in the dock once and then nothing else.

The target machine is running OS X 10.4.11 server. It has 2 quad core 3 ghz intel xeon processors (Mac Pro 2,1). I'm not sure if it's the age of the OS, that it's server, or the processors that I'm not built for correctly.

In Xcode I'm building for both 32 bit and 64 bit architectures. My Base SDK is 10.6 (the lowest I can go). Valid Architectures are i386 x86_64. The compiler is Apple LLVM compiler 2.1 The Deployment target is set to 10.4.

Can anyone see something that is set up wrong?

If memory serves, in 10.4 GUI apps could only be 32-bit. In OS X 10.4, Cocoa and Carbon were 32-bit only. Only build for 32-bit and see what happens. Also, make your app log its startup progress to a file so you can see exactly where it's having trouble (if it's getting launched at all).

Make really really really sure you aren't trying to use something not present in 10.4.

It used to be that you were given the option to install the 10.4 SDK when you installed Xcode, but not anymore evidently.

Sounds like you're going to have to go back to a non-Mac App Store version of Xcode. They've got the option during install to install the OS X 10.4 SDK if I'm not mistaken.

Supporting legacy systems like that is a major PITA. Especially if you're also trying to support more modern systems and features.

Thanks for the push in the right direction. With a 32 bit only build I get a crash log.
code:

Some googling tells me it's a problem with the LLVM compiler, and that the fix is to use the gcc compiler. If I use the GCC Compiler it won't build because GCC 4.2 requires build target of 10.5 or later. I guess I'd need GCC 4.0 but that isn't available. So apparently I'm screwed.

Keep searching on __NSConcreteGlobalBlock, there's a bunch of stuff about it that's more varied than "change the compiler" but I don't know what's relevant for you.

10.4 doesn't support blocks; the runtime support just isn't there. I mean, technically there are a couple things you can do with them, like pass them around (but not to any system functions, which do not exist) and never copy them ever, but if you're doing anything interesting at all, you will see failures. If you need to deploy back to 10.4, you must not use blocks.

There are workarounds if you really want to pretend that blocks exist there, but the better answer is that 10.4 is a really old OS at this point, and OS upgrades are not that expensive.

Can someone explain why linking windows is so unbelievably loving difficult? I'm trying to create a main window for this map application the book wants me to make because I'd rather just learn how to make the window than use their hacked file. I keep getting errors saying that the nib was loaded but no view was set.

http://www.makebetterthings.com/iphone/where-is-mainwindow-xib-in-xcode-4-2/

I tried all of the solutions here. I linked the app delegate to the window as its delegate, set the window as the view controller/changed the class as it mentions, and I tried modifying various lines in the actual code. Nothing works. It's late and I'm just going to go to bed, but I'm really loving frustrated with how illogical this poo poo can be sometimes. Maybe MVC is just a really confusing thing that I'm simply not getting, or I'm (once again) doing something horribly stupid, but I'm following the instructions that people said helped resolve their issues and it's just not working.

I don't want to quit on this poo poo, but it's becoming absolutely infuriating at how some of Objective-C/the Framework's design works, and Xcode doesn't seem to do much to help you. It's not helping my case for not trying to work with C# instead. Perhaps I should just try their hack or simply skim over the rest of the map app chapter I'm on and move on until I follow the book's later guides to creating windows and the like. Who knows. (Sorry in advance for the rant. I'm just really frustrated.)

Thanks for the additional info. I didn't use blocks in my code, but I did use GCDAsyncSocket for networking so I expect that's where it's coming from.

Upgrading 10.4 isn't really an option right now. One of the main apps we use is still ppc only, when Lion killed Rosetta it killed our ability to upgrade. We'd have to track down a used copy of snow leopard server. It's actually put us in quite a bad position, because we also can't buy new computers and these are heavily used production servers.

This all has to do with automated page pagination for a printing press. We have 1 server that feeds 7 plants and if you ask me it's retarded that we've put ourselves in this position. In fact we make fun of our customers who still use quark 4 and then have their 12 year old computer die because they put themselves in the same position we're in now.

I might have to suggest running my app on a different box, it's not ideal, but it would work.

Yeah, 10.4 doesn't have Grand Central Dispatch.

It would be worth it to upgrade to 10.6, which has most of the niceties of 10.7 but still has Rosetta. You could use blocks, GCD, etc.

A better solution would be to find a replacement for that PPC app, though I'm sure you're well aware of this

Follow the second tutorial you linked. Worked for me, does it work when you try? Remember, when you change the class names in Interface Builder you have to press enter after you type in the class name, or it won't take.

So when you change the class of File's Owner to UIApplication you have to press ENTER afterwards.

Here is a working test app, made by following your second link.

Relevant to the other post before yours, there were three lines of code in the AppDelegate.m which were screwing with the window. I'm still not so great with self understanding, but it appears Xcode 4.2 was having the delegate allocate a window for itself. I don't know if that's a nuance of 4.2, but the code was automatically placed there. At least it works now, I guess.

I didn't remove any code and it still worked.

As for self it's pretty much the equivalent of C++'s this. It points to the current instance of whatever class the object is. So if you make an object foo that has method bar, and in the code for foo you need to call bar, you'd do

code:

[self bar];
// and can access properties like
self.someProperty = 5;
// or like this if you're like the guy that wrote the BNR book and hate dot-notation
[self setSomeProperty:5];

I was trying to add the window for delegates from a previous chapter. Xcode had made a window for the project but there's been some odd issues with linking which I mentioned before; someone had linked to a temporary fix which the book's authors posted on their forums. I tried making a new window and it might have been referring to the old one which was being created from within the delegate file using self.

I'm going through the Stanford online class and there's a point where he adds a ViewController, and has a checkbox option during its creation to make it a TableViewController. It appears that this option is gone from the latest Xcode, so to follow along is it just as simple as creating a regular ViewController and implementing UITableViewController or is this indicative of some deeper chance with the way these things work?

If you installed it through the app store, then downloaded the update through the app store, you'll need to run "Install Xcode" again. It will say update rather than install on the button. I did the exact same thing. They don't really make it clear on the app store.

I'm mixing C++ and Objective C because I'm a bad person and have had a nightmare of a time after upgrading some of the libraries I'm using as well as XCode, but after multiple reinstalls the problem I am left with is this:

C++ class declarations using NSObject as a base

code:

class myClass: NSObject{

are giving the error 'Base specifier must name a class', yet in my Objective C files the

code:

@interface myClass:NSObject{

is working all hunky-dory, and yes I am importing foundation. I'd downgrade back to an earlier XCode (I think I was using the last 3.* before and it worked) but I'm hoping there is a solution that is less of a pain in the rear end than screwing around with the project to compile it. Or rewriting everything into ObjectiveC :cry:

I kinda expected Google to come up with something obvious but apparently I've managed to screw up in a way nobody else has.

Is there a setting I need to enable somewhere to make this work?

Making C++ classes inherit from ObjC classes is something that technically GCC lets you do, but only accidentally, and it has never actually worked unless you basically do everything yourself. I mean, your objects won't even get a class pointer, and you certainly can't define ObjC methods on your class, so I am skeptical that this was ever useful for you.

Anyway, this is considered old badness, and Clang has never supported it. Your Xcode upgrade probably switched you to using Clang. Technically you can switch back to LLVM-GCC, but please just stop doing this. You really don't have to rewrite the entire world in Objective-C; you can have ivars of arbitrary C++ types (as long as they're default-constructible), you can write arbitrary C++ code in your method definitions, etc. You just can't naively mix the class hierarchies.
