Hello, I want to programmatically initialise my tabBarController to the last tab selected by the user. This works OK for my standard tabs, but if the uwer was on the "more" tab, I cannot figure out how to initialise it as this tab doesn't (to my knowledge) have an index). Is anyone aware of a way of doing this? ...
Why are people using @interface ViewController : UIViewController { @private UIButton* button_; } @private declarations in public headers? Declaring a variable inside an implementation yields the same result, doesn't it? It feels strange to me, I thought a public header should only contain really public members. What to do with ...

I seem to have the exact opposite problem than this question on stopping dock bounce. I can't get my app to continually bounce the dock icon! I too hate continually bouncing dock icons, but in this case if the user doesn't realise my app can't launch, they could potentially lose hours of time tracking data. Here's my code that I've p...

Does anyone know where I can start? Oh, yes I did some searches, but I couldn't find anything useful. Thanks in advance. ...
Hola. When I receive a list of MDItemRef items returned from a Spotlight query (in obj-c) I was wondering if there is an easy way to determine if they come from the OS install drive vs. an externally connected USB drive. The basic premise is that I want to ignore anything from the local drive and only watch for files on external USB...
I'm experimenting with Obj-C blocks and trying to have a struct with two blocks in it where one block is to change what the other block does. this is a really roundabout way to do something simple... and there may be better ways to do it, but the point of the exercise is for me to understand blocks. here's the code , it doesn't work, s...

I cant understand what this warning I get on Xcode is about. Searching for it on google wasn't of too much help. If anyone has come across this warning before, it'd be great if I could get some hints on how I'd be able to get rid of it. The (updated) screenshot is at: http://imagebin.antiyes.com/images/0116033001255720169%5F90.png Tha...
I am creating a program for mac that needs to generate reports and be able to print them as PDF files. I would rather find an already created library for this rather than hard-coding everything, but I can't find anything yet. Do you recommend any report generation libraries that can be used in Objective-C? Thanks for your help! ...

I would like to understand garbage collection in objective-c. I know how to work with memory in C-like languages and in languages where I don't care about memory. But I don't understand when to use autorelease, retain, dealloc and everything else, so I get errors and memory leaks. Could someone propose me a good tutorial to understand ...
Hi, I am trying to make a code hard to crack using Objective-C on a Mac. One of the things I have to do is to check to see if the application was cracked. I am new to Objective-C and Xcode and whatever way I imagine to test my application I always end in a basic test that can be patched easily. For example: suppose I am about to te...
