xcode4.2

I am trying to get in to some graphics in C++. I figured it was best to start with the most capable graphics framework so I am going with the OpenGL included in Lion. Basically I started a command line tool in C++ in XCode 4.2 and that's all I have done. I need to somehow link OpenGL with the XCode so I can use it. After I get it set up on my Mac platform, I hope I can use a basic how-to guide for OpenGL for C++ to get further as, if you haven't noticed, I am not entirely clear on how to precede. Pretty much all I have read is some background information on how OpenGL uses the CPU and GPU

I upgraded my iPad to 5.0 a couple days ago, and upgraded Xcode to 4.2 at the same time so I could continue to test my apps. Now I am having problems with touch code in several apps that worked with previous versions of Xcode. I subclassed UIImageView to add some dragging features by overriding -(void)TouchesBegan and -(void)TouchesMoved . I did not override -(void)TouchesEnded in the subclass, but handled that in the view controller for the view that contains the image view. I pulled the subclassed UIImageView into a new project for testing, and have narrowed down the issue to the fact that

I started to use Xcode 4.2 and i have problems with generating code coverage. Xcode 4.2 does not include the GCC 4.2 compiler, but it was replaced with the LLVM GCC 4.2 compiler. The first one was needed to generate code coverage in the previous version of Xcode. I followed the 'tutorial' on CoverStory website , but this results in the following: a) when i do all steps, no coverage files. b) when i link the libprofile_rt.dylib to my project, the test which should fail, do not fail anymore. Did anyone encounter this issue? And how did you solve it? Thanks Here is a way to enable compiling with

EDIT: changed the title. I didn't know it at the time but this is a duplicate of Why am I crashing after MKMapView is freed if I'm no longer using it? This question is similar to Why is object not dealloc'ed when using ARC + NSZombieEnabled but different enough that I thought it worth throwing out there in case anyone understands and can explain to me what is happening. The other question may be an XCode bug so I presume this could be similar. Scenario: RootViewController has a tableView displaying a bunch of items Selecting a cell presents a modal detailViewController containing another

I am developing an app using XCode 4.2 and I am trying to create an ABPerson using initWithVCardRepresentation and/or ABPersonCreatePeopleInSourceWithVCardRepresentation , but I can t find a working example . can someone help? I get the VCard in an NSString format.... Thanks This is a full example and it works perfectly, it bases on the latest iOS 8. First of all you should check authorization status and request access right if not, then save the vcard, let just review the code below: if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized){ NSLog(@"Authorized"); [self

Out of the blue, the "symbol navigator" (second icon from the left in the navigator pane) started just giving me access to a single .h file. The "project navigator" continues to display the entire project. I've tried flipping things back and forth, restarting Xcode, etc, to no avail. It's stuck on that one file. The one clue I have is that the .h file is the only .h in the project's second target, a test target. But I don't see any way to select a target (vs the project) for navigation by the symbol navigator (and I definitely didn't "play with" any settings that might affect this.) Any ideas?
