Most questions regarding this problem are due to missing Xcode; I have Xcode 4.2 installed.

Install attempt:

    rvm install 1.9.3

Based on config.log (posted at bottom due to size) I tried symlinking gcc-4.2 to gcc and then installing:

    rvm install 1.9.3                       
    ERROR: The autodetected CC(/usr/bin/gcc-4.2) is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`, and set CC=/path/to/gcc .

So I could probably just grab gcc elsewhere, but I&#39;m mostly concerned as to why this is happening. Shouldn&#39;t installing Xcode be enough?

Can&#39;t install Ruby under Lion with RVM – GCC issues

I am trying to adjust the cell height for one of the cells on my table view. I am adjusting the size from the &quot;row height&quot; setting inside the &quot;size inspector&quot; of the cell in question. When I run the app on my iPhone the cell has the default size set from the &quot;row size&quot; in the table view.

If I change the &quot;row size&quot; of the table view then the size of all cells changes. I do not want to do that as I want a custom size only for one cell. I have seen a lot of posts that have a programmatic solution to the problem, but I would prefer to do it through storyboard, if that is possible.


Custom Cell Row Height setting in storyboard is not responding

For the most part with ARC (Automatic Reference Counting), we don&#39;t need to think about memory management at all with Objective-C objects. It is not permitted to create `NSAutoreleasePool`s anymore, however there is a new syntax:

    @autoreleasepool {
        …
    }

My question is, why would I ever need this when I&#39;m not supposed to be manually releasing/autoreleasing ?


----------


**EDIT:** To sum up what I got out of all the anwers and comments succinctly:

**New Syntax:**

`@autoreleasepool { … }` is new syntax for

    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    …
    [pool drain];

**More importantly:**

 - ARC uses `autorelease` as well as `release`.
 - It needs an auto release pool in place to do so.
 - ARC doesn&#39;t create the auto release pool for you. *However:*
  - The main thread of every Cocoa app already has an autorelease pool in it.
 - There are two occasions when you might want to make use of `@autoreleasepool`:
  1. When you are in a secondary thread and there is no auto release pool, you must make your own to prevent leaks, such as `myRunLoop(…) { @autoreleasepool { … } return success; }`.
  2. When you wish to create a more local pool, as @mattjgalloway has shown in his answer.




Why is @autoreleasepool still needed with ARC?

I still have Snow Leopard. I have Xcode 4.2 for iOS development. This morning I upgraded my iPhone and iPad to iOS 5.1. 

But Xcode 4.2 is not detecting my device for testing. I could not find the iOS 5.1 SDK image on Apple&#39;s developer site, for Xcode 4.2.

I don&#39;t want to do upgrade to Lion to get XCode 4.3 at this time.

Will I able to use Xcode 4.2 (on Snow Leopard) for iOS development now?

Is it possible to get the iOS 5.1 SDK for Xcode 4.2 on Snow Leopard?

I&#39;m currently developing an app for iPad. The development started for iOS 4.2 and is now continuing (and I think will be completed) for iOS 4.3.
I just read about ARC in iOS 5, and basically I understood that we will never need to release and retain objects anymore. My questions are:

1. If I decide to upgrade to iOS 5, do I need to remove all `[myObject retain]` and `[myObject release]` statements from my code?

2. If I develop a new app for iOS 5 using ARC, will I need to implement some sort of &quot;retro-compatibility&quot; checks? i.e.: will I need to check the version of iOS and call retain and release accordingly? So, basically, is ARC available for all iOS versions or just for iOS 5?

My objective is to create a tabbed application, then the view for each of the tabs are constructed in separate storyboards.

![Storyboard screenshot][1]

My mainstoryboard is a tab view.

Then I create a secondary storyboard (storyboard#2) with 2 View Controllers. The first view controller (also ticked as initial) have a button, and segue (modal) to 2nd view. ![First view controller][2]

I managed to load the view by subclassing and overriding loadView from storyboard#2.
![loadView override][3]

Here&#39;s the simulator output.

![Simulator][4]

When click on the &quot;click me&quot; button, I get a `EXC_BAD_ACCESS`. The segue does not work, seems like the second storyboard is not being loaded completely.

Has anyone tried to do this before and get it working? There&#39;s a youtube video from SkillMaster.net but he does not demonstrate if a segue is working under the secondary storyboard. the video is here: http://youtu.be/D4_twoYvB4M

Thanks for any input and help!

Using Multiple Storyboards in iOS

I keep searching, but cannot find **a clear and simple explanation on how to include one XCode project, along with all of it&#39;s sub-classes into another project.** I routinely see stuff like that in sample projects that I download off the web, but do not know how to do this myself.

Within XCode, along with .h and .m files, and folders, there&#39;s a whole new project, starting with a blue xcode project icon, that is expandable to contain everything within the project. 

Please, can someone explain to me step by step what do I need to do to add one XCode project into another one? I&#39;ve seen a ton of one liners like &quot;header search paths&quot;, but that does not tell me much. 

**UPDATE: After re-reading the documentation, I realized that the project to include must be dragged ONTO the BLUE project icon of the parent project.** Regular sources can be dragged anywhere, but a  project must be dragged onto a project.
 
Thank you!

When creating a project in Xcode 4, it asks what Class prefix to add to all new files.

Is there a way to change (or remove) this, after a project is already started?

I have imported the three20 project into my project, and when I upgraded to Xcode 4.2 with iOS 5, a bunch of warnings appeared in the project.  

I don&#39;t care about them, but they make a lot of noise, and it&#39;s easy to miss any real warnings in my project now.  Is there a way to disable warnings for those specific libraries?

Is there a way to merge XCode 4.2 Storyboard files? 

I&#39;m working with another developer on an iPhone project and all my attempts at merging changes into a storyboard file have met with failure and after which Xcode is no longer able to load the storyboard. Consequently I have to do an svn revert and then redo my modifications.

When view is loaded manually, developer remains in control when it comes to initializations, we choose what initializer to call, what variables to set etc.

When view is loaded from the storyboard segue ... what happens to that initializer? Where should variables be set i&#39;d like to be available once view had been loaded?

Please help me understand the sequence here. How is instance of the class created here, who creates it and how can we intervene and help set it up to our liking?

I&#39;m unable to change the price of an in-app purchase. I added initially for testing purposes, but now that I&#39;m submitting the app, I&#39;d like to change it. Unfortunately, it doesn&#39;t seem to accept the change. It is showing me the same price tier not the updated one.what should i do ?

I created a Text Field in Interface Builder.  I set it&#39;s &quot;Return Key&quot; to Done.  This is a one line only input (so it wont need multiple lines).

**Can anyone help me remember what was the flag to tell the XCode to not use ARC for some file?** I had several files in my project marked as such... Until I added another file and decided to convert that one to ARC. Sounds easy, right? I expected that I would be able to simply check a file that I want and let the XCode do it&#39;s magic. Well, not so easy, during pre-check it stripped all -Noarc flags from the files and now I need to manually re- apply the flag to several files. 

the moral of this story is: **once your project is in ARC and you have some files marked as no ARC, do not re-run the convert to ARC tool from Refactor&gt;Convert to ARC.** It will not restore your settings even if pre-check fails.

I have found a few other posts that show how to add a script to increment the build number with a script:

https://stackoverflow.com/questions/9258344/xcode-better-way-of-incrementing-build-number

https://stackoverflow.com/questions/7371345/xcode-projects-build-number

https://stackoverflow.com/questions/4694070/can-xcode-insert-the-version-number-into-a-librarys-filename-when-building

But what I want to do, is only increase the build number when I use ARCHIVE (both before and after).

Example:
If current build number is 21, then when I choose Product &gt; Archive the build number will be increased to 22, it will go through its process of building and creating the Archive file with the build number of 22, and then when it is finished archiving, it will increase the build number to 23.


Xcode-Increment build number only during ARCHIVE?

I have a Cocoa app that has an `NSWindowController` controlling an `NSWindow` with an `NSComboBox` in it. Nothing special, and it worked fine until upgrading to OS X 10.7.2. Now I get the following exception, which occurs only once, when the window controller&#39;s window loads. (Since the window controller in my app remains loaded, it happens only once per app launch.) Subsequently focusing and unfocusing the combo box does not trigger it.

Anyone know whether something changed in 10.7.2, and if so how to work around it?

(This is happening with Xcode 4.2.)

Unlocking Focus on wrong view ((null)) under OS X 10.7.2

I&#39;m using XCode 4.2 and have built my UI using Storyboards. I need to create a view that has content above and below a UITableView and I can achieve this by using a UIViewController.  A UITableViewController does not let you add content above or below the table.  You can use the table header/footer but that doesn&#39;t work for what I would like to achieve.

I now have a UIViewController with a UITableView embedded in it.  I can adjust the height and width of the UITableView accordingly which provides me the UI layout that I am looking for.

I can customize the static cells in the UITableView but when I try to build I get the following error:

&gt;Illegal Configuration: Static table views are only valid when embedded in UITableViewController instances

My question is how are others getting around this?  Creating a tableview with static cells and laying them out visually is very nice but apparently that is not allowed for some reason that I cannot understand.  I can&#39;t switch to a UITableViewController because of my visual layout requirements.

Any assistance would be greatly appreciated.
