In my app, there is a portion that holds a static contacts directory. I would like the directory to appear indexed (alphabetically) and the detail view will need to be grouped also. (I am somewhat trying to replicate the look and feel of the Contacts app.) I have it working, just no index and a detail page that is just a view with a col...
As I was sifting through some of the Xcode project flags, I stumbled across a flag called "Auto-vectorization" which enables the compiler to optimize operations to take advantage of vector registers (where applicable). Why would I ever turn this off? Are there performance considerations (it should be better)? I don't really care about...
I'm diving into iOS development and I just found out about the Static Analyzer and it's been pointing out all sorts of mistakes I was making in the code. The Static Analyzer doesn't really seem to eat up any extra time when building and so I'm wondering why it isn't enabled by default. Are there any reasons you wouldn't want to use the...

In the code below, CTFramesetterSuggestFrameSizeWithConstraints sometimes returns a CGSize with a height that is not big enough to contain all the text that is being passed into it. I did look at this answer. But in my case the width of the text box needs to be constant. Is there any other/better way to figure out the correct height for ...
Hello, As the subject says, I have a project based on Apple's TabController template. The problem is that when navigating to Second View in the TabController, the First View's "viewDidLoad" method is called. The second view's method is NOT called. Any idea what might cause this? I would post code but I'm not sure what part might pertai...
Hi, I have a pretty obscure problem here. I'm writing a photoshop plugin (for mac) using Xcode. I use printf statements for simple debugging. A printf without a format string works fine, however, if I use a format string to try and print out a value it does not show up in xcode's debugger console. #include <stdio.h> DLLExport ...
I've been using agvtool for one of my iPhone apps on general principle, and have recently found a reason why I want to be able to check the version variable (so that I can re-copy help content into the Documents directory, if it's out of date). The variable, MyAppVersionNumber, defined in MyApp_vers.c, is auto-generated during the build...
Hey guys, I looked thru the documentation a bit but didn't see anything of much substance (but I must not be looking in the right place) What are my options if I want to iterate through a user's itunes library meta data? Let's say I want to build an Array of all their song titles. Is this possible with current public SDK APIs? Dave ...
I noticed that there are some words that XCode does not recognize. For example the word initWithCoder. It also won't recognize NSString if the word const comes before it. How can I fix this? ...

Hi All, Here is a list of problems I have after building my app with xcode 3.2.3 and running it on simulator 4.0. Of course, all these issues did work with the previous environment. Location manager does not update location. It used to update with the location at Cupertino but now I get locationManager:didFailWithError: called with er...

I'm following a tutorial from chapter 12 of the book "Beginning iPhone 3 Development." When I try to build the project I get an error. The book came with the project files, so I went through every file in my Classes directory and copied and pasted the code from the example project so that they are identical. This has solved my build erro...

My problem is something that should be so simple it is mind boggling. When I change the look (in PhotoShop) of an image file that is being stored in my app bundle. My method for replacing the old image in the bundle with the new one is this: 1) remove the old image from the app bundle (choosing to also move to trash) 2) drag the new i...
I have duplicate symbol _main. The problem is it says "Duplicate symbol _main in /Users/.../i386/main-B9843B6026D6EFA4.o and /Users/.../i386/main-B9843B6026D6EFA4.o", the XXX and XXX are actually the same .o file. I don't know why it thinks it's duplicate symbol when it's the same .o?! Any help appreciated, thanks. ...
