IPhone (SDK) Developer Forum

Is there a developer forum area specific to the iPhone?

Not yet.
I requested one in the feedback/discussions forum, you can add your 2 cents there. Hopefully someone will see it and create one.

IPhone SDK developers...

Hi,
Is there a 'forum' located somwhere (anywhere!) in the "developer's connection" pages?
It seems odd to me that there is no forum for those of us developer types to talk with each other regarding iPhone SDK development.
For example it would seem silly to ask in THIS forum area (anywhere under the iPhone main heading) ...
"Where can I find anything in the SDK that allows me to see/modify/update the SYSTEM PREF Bundle??"
Is there an off-apple-site (usenet?) group anywhere for these kinds of questions?
thanks,
tob

IPhone SDK: unrecognized selector

I'm relatively new to Objective-C/iPhone SDK development. I have an issue that really seems to produce random (or at least nondeterministic) errors, all of which are "unrecognized selector" errors.
I have a UITableViewController that is populated with table names from a MySQL database. When I select a table name, a second UITableViewController is created to display detailed data. I thought this was working just fine, but I discovered I have problems when I select a certain table name, (detailed results are displayed in second UITableViewController), go back, select the same table name, (...), go back, and select the same table name a third time. The Simulator explodes and gives me an error like:
* -[UICGColor length]: unrecognized selector sent to instance 0x1050810
Sometimes it's related to UICGColor, sometimes it's related to CALayerArray. Sometimes it doesn't produce any error at all and just terminates.
What's also weird is that only some of the table names cause this to happen. Also, if I cycle through several table names (i.e., not select the same table over and over), the app is fine. I would tend to think that maybe something is wrong with my database or MySQL C API usage, but the fact that things are perfectly fine the first and second (and third and fourth and ... and nth for some tables) time baffles me. I'm not using any dynamic method calling either -- just straight
[ object method: ] syntax, so I'm not sure how it suddenly can "lose" the selector reference that it was perfectly happy to use earlier. As far as I can tell, I'm releasing memory as necessary.
Any clues why this seems to be so weird and unpredictable? I can provide source if it would help.

Ugh. Problem solved. I was tampering with autorelease, and it got me into trouble. I had this:
query = [ [ [ NSString alloc ] initWithFormat:@"...%@", [ [ tableView cellForRowAtIndexPath:indexPath ] text ] ] autorelease ];
I thought that I should autorelease the "anonymous" object I created. It made sense at the time, but upon thinking about retain/release more closely, it's so clear now.

Request for iPhone developer forum

There has been a recent influx of new iPhone developers in the developer forums. They often don't identify their problem as being specific to the iPhone. You have to look at what they are talking about and see that it is all iPhone stuff. Apparently the iPhone SDK is significantly different enough that answers to basic questions for MacOS X development are not correct for the iPhone SDK.
If there were an iPhone SDK forum they might be more inclined to put iPhone-specific questions in there.

I completely agree with the previous sentiments for an iPhone developer forum. Why?
I am part of the problem. I have come into the Apple development process "solely" to work on the iPhone. I know nothing about Mac OS X. Because of that I was astounded that the iPhone documentation was not "iPhone" but rather Xcode documentation. Yes I understand that there is a great deal of overlap BUT from my point of view it looks as though Apple was extremely lazy in just dumping all of their code and documentation on the iPhone developer. They need about 5 editors to weed out what is and is not iPhone. Just my two cents.

Which forum to post in for iPhone software development?

Hello; I'm a newbie at iPhone software development. Is this the correct forum to post in if I have a question on iPhone software (application) development? A point in the right direction would be appreciated. Thanks! -John

I am assuming even though you list a Windows computer that you are using an Intel-based Mac for your development.

Iphone developer program or free iphone sdk - where is the difference?

I am a bit confused.
on one hand I can download the free iphone sdk on the other hand there is the $99 iphone developer program.
where is the difference?

And the Developer Program isn't the computer kind of program. It is the other kind, meaning "a plan or system under which action may be taken toward a goal." It is how Apple tracks those who want seriously want to distribute to through the iApp Store.

IPhone SDK Simulator - How to uninstall application developed

Hi,
I downloaded the HelloWorld sample for iPhone SDK. Compiled and was able to run the application.
How can I remove the just compiled app from the simulator? I even tried uninstalling the iPhone SDK and upon reinstalling it, I still see the icon in the simulator and able to run the HelloWorld app.
Thanks.
ST

Click and hold the application icon on the home screen. As soon as the "x" appears, click the "x". Then click the home button.

Cannot use AddressBook Framework for iphone SDK

I am trying to use the AddressBook Framework with iPhone SDK, and I added the following framework to my xcode project:
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Lib rary/Frameworks/AddressBook.framework
When I compile, references to classes such as ABAddressBook and ABPerson cannot be resolved. ('ABPerson undeclared ...'). However, It seems the C interface to AddressBook is defined.
I am using the framework in the iPhone SDK directory, and I have #import <AddressBook/AddressBook.h> in my header file, but it is not working for me. Any tips would be appreciated.

It does explain the OP's problems
Conserning add and checking if there are changed records in the addressbook I hear people complain about it and got refered to apple to report it as a bug for the sdk.
And since we still are limited when it comes to mentioning the api I will rather link something someone else wrote on the topic before.
Have a look here: http://forums.macrumors.com/showthread.php?p=5495200 that should give you some of the basics.

Developer forums?

Is there a iphone developer Forums? Ive got some programming questions..
I cant even find any iphone mailing lists...
Thanks

The iPhone SDK is not "released to the public" with "no strings attached". To obtain the kit, you have to sign up as an iPhone developer and agree to the terms of use which do include a nondisclosure statement. The fact that the SDK is free should not be taken to mean that it's completely open and available with no strings; that's just not the case.
I understand that. My only point was since anyone can sign up to be a developer (I did and I have never coded a thing in my life) having a NDA seems a little pointless.

Which version of iPhone SDK is available for MAC OS 10.3.9

Hi,
I want to develop an application for iPhone using my MAC OS 10.3.9 version.
Which version of iPhone SDK is available for MAC OS 10.3.9?
Can I install and work with iPhone SDK 6 or 7 version on MAC OS 10.3.9.
Regards,
Punit

but the installation steps of SDK says that it can be installed on MAC OS 9.3.x also by customizing it during installation for the MAC OS 9.3.x.
If possible, could you post a link to where this information is.
OS 9 does not have a version 9.3.x so I am not sure what you are referring to unless that was a typo and you meant 10.3.x?
I think you might get better support in the Developer forum. If you don't receive any other response here in this topic perhaps posting there might attract more knowledgable SDK users.

IPhone SDK 2.0 - xcode fails to build new project

I downloaded and installed the latest iPhone 2.0 SDK. I did not uninstall any previous tools (xcode/SDK). I assume the 2.0 SDK installation will perform the upgrade in a proper fashion (not requiring one to uninstall the previous SDK/xcode). I start up xcode. I check the version via the about menu. It states that the version of xcode is 'Version 3.1 (Beta)'. The project settings indicate that the Base SDK is Device - iPhone OS 2.0. I checked my system to ensure that my current filesystem has the correct SDK. It has the Macintosh HD->iPhoneOS.pltaform->Developer->SDK's->iPhoneOS2.0.sdk.
OK, everything seems good up to this point. I create a new xcode application for the iPhone. I then go to compile the application and I get the following error:
/Developer/iPhone Examples/Foo/Classes/FooAppDelegate.h:16: error: syntax error before 'UIToolbarController'
Source code line : UIToolbarController *toolbarController;
Yes I realize that the UIToolbarController API has been removed for SDK 2.0. However, how can one use xcode to build a starter application if it is generating code that references outdated API's???
Am I doing something wrong? I have searched all the forums but have not come across this issue. Hence, I think something is wrong with my setup/install. If the solution is not to use UIToolbarController API, then why does the xcode still use it to build starter code projects? Also, if we can't use the API, what is it's replacement?
thanks

It created more errors, as there are a whole lot of other API's
that have changed (UIViewController now doesn't resolve
some of it's members, e.g. toolbarItem).
Err... hello? Someone just told you what the names have changed to!
Wow. I have about 1 months worth of work, that I am going to
have to seriously think about throwing away because of all of
these growing pains.
Can't talk about the iPhone SDK specifically, but Xcode in general has great refactoring tools that will make the name changes, in all locations, in a split second for you. No, lets not get hysterical. It's not one month's work at all. It's not even five seconds work.
I think the newer 2.0 release is causing more problems than solutions.
That's the whole point. It's not a release. It's a beta. That's what happens with beta's. That's why you sign an NDA (non-disclosure agreement), stating that under no conditions will you discuss the SDK with anyone, and that you agree that things may change without prior notice or even break down completely.
Basically shutting down all of my development efforts.
Errrr.... hello again?

IPhone SDK Beta and Unix Tools

Does anyone know how to compile Unix tools for the iPhone with the SDK? All I seem to be able to find is, "install the toolchain". That doesn't help.
Specifically, I'd like to compile ettercap-ng. I know ettercap has ARM sources and even an ARM .deb in the apt-get repo (for debian). Given all that, it shouldn't be hard to do.
I've already got some dev tools on my actual iPhone, and I can use a terminal emulator to issue the compile and make commands.
I'm trying to compile ettercap-NG 0.7.3, and every time I do, (cd /{ettercap source here} && ./configure) I get:
checking whether make sets $(MAKE)... (cached) yes
checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.
Seeing as that's as far as I seem to be able to get on the actual handset, does anyone know how to use the SDK on a MacBook (Leopard 10.5.3 so on and so forth) to do it, and then transfer it over?

Mark, You have to be a registered iPhone developer to have the beta level firmware that allows direct access to the iPhone via the SDK. As far as accessing the BSD file structures the only way AFAIK thats currently possible is to hack the phone. And of course we cannot discuss that on this forum....

Learning iPhone SDK - Trying to draw an image

Although I have programmed for Mac in the last years, I have never used Mac-specific technologies as Cocoa (I have programmed more in OpenGL, SDL, and the like).
Now I am getting started with the iPhone SDK. I'd like to do some OpenGL|ES stuff, but since it is not supported in the Simulator, and you need to join the Developer Program to test stuff on directly on the device (and admission of new members is closed right now), I am focused on other stuff right now, like using Core Graphics for drawing images on the iPhone.
My application is based on the Cocoa Touch Application template. I left the default code except for a few changes.
In file "UntitledAppDelegate.m", I have changed the method applicationDidFinishLaunching to:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
contentView = [[[MyView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease];
[window addSubview:contentView];
[window makeKeyAndVisible];
Then, in the MyView interface file (MyView.h), I have added the attribute "UIImageView* image;" to the class, which is declared as a property, and synthesized.
In the class implementation (MyView.m), I have changed the method initWithFrame to:
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
self.backgroundColor = [UIColor darkGrayColor];
image = [self loadImageView:@"box01.png"];
[self addSubview:image];
return self;
loadImageView is a private method I have implemented as:
- (UIImageView *)loadImageView:(NSString *) imageName {
UIImage *img = [UIImage imageNamed:imageName];
UIImageView *theView = [[UIImageView alloc] initWithImage:img];
return theView;
Since I have loaded the UIImage, and initialized a UIImageView with it, and the image view is added as a subview of the main view attached to the window, I thought it should be everything needed to draw an image on the screen. But nothing is visible. The screen is simply black when I run this on the Simulator. It doesn't even set the background to dark gray.
So I need some help with this, I sure that anyone with experience in Mac programming will know how to help me.
Thank you in advance.

I removed the XIB file from the project, but that didn't help. It was a problem with my inexperience with Objective-C. When accessing class properties in a method of the same class, i was not putting "self." before the property (in C++ that's redundant). For example, in the line "window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];". After adding it, it works correctly.

IPhone SDK CodeSign Error: Redux (latest OS X update is broken)

This bug - http://discussions.apple.com/thread.jspa?threadID=1455699&start=0&tstart=0 - is back. My AdHoc project, which worked perfectly last week, has just stopped building, with this:
"object file format invalid or unsuitable"
As soon as I upgraded from 10.5.7 to 10.5.8, this bug appeared.
However, this bug was officially fixed in 10.5.7 - so, I'm guessing here, Apple has accidentally re-created it.
Unfortunately, I cannot add to the original post, because Apple has frozen the topic.
So, here's a new topic to ask if anyone else is having this problem, and what they did about it - is it exactly the same as the old bug? or is it different in some way?
I'm going to try some of the workarounds for the old bug - but hacking command line scripts isn't fun, and I'm worried I might break something even worse .

Running iPhone SDK & Leopard on G4 1.42 emac?

Looking for a cheap entry point to get into developing apps for iphone. I can get the 1.42ghz G4 emac for $200 or G5 PPC 2.0ghz for $775.
I've read that the G4 will run leopard, but havent found anyone running leopard and iphone sdx on the G4. I'd like to try things out first on the G4, but is it going to be so unbearably slow that I'm going to regret taking the cheap way out? Thanks.

Further research has led me believe now that iPhone SDK will only run on Intel based machines. If that is indeed the case, neither machine will work for me.
