I have an NSArray formed with objects of a custom class. The class has 3 (city, state, zip) string properties. I would like to get all unique state values from the array. I did read through the NSPredicate class but couldn't make much of how to use it in this case. The only examples I could find were for string operations. Can someone ...

The docs say that the Media Player framework will play video only in fullscreen. In my case I want to play video in a little portion of the screen, while using UIKit / UIView. What would help out? Do I have to use an openGL ES view for that? ...
my app asks the user yes-no questions, user replies using a uiswitch on screen. i've been thinking about creating a custom version of the switch that would display yes/no instead of on/off and would use a green/red background as an indicator of the value. after creating a mock up i'm not so sure this is the way to go. using the default s...
After upgrading to OS X 10.6 (Snow Leopard) and iPhone SDK 3.1 (with Xcode 3.2), Xcode's shared workgroup builds (distributed) can't seem to find or access other computers in our office. Distributed builds worked perfectly in OS X 10.5 with iPhone SDK 3.0. All the computers that have upgraded are now listed with a status of Unreachable...
I have spent a few days trying to get around the limitations with UITextField, namely no text wrap and number of lines. I have created a UILabel, which is used to display the text entered in UITextField and does all the formating stuff properly. The UITextField is hidden and the user sees all the texted entered only in UILabel as it's be...
I recently moved my projects to a new mac, along with a newer version of Xcode. When i opened my project i noticed that some files were red. So i remapped them by setting the path (by project path) and then providing the proper path location. Now my problem is that the frameworks that i have are red, and i cant find their location! I d...

I have a pretty simple question. While I am fairly new to Objective-C, I have gotten pretty comfortable with the language and the memory management model. I understand ownership pretty well and the notion of explicit and implicit. I also understand that when you add anything to a collection, it takes ownership of the keys and values a...

I've noticed in some of the examples ive seen that you will set a engine( class variable ) to a _engine ( ivar ). I don't get it. What's going on here? Here is an example of what I'm saying: @synthesize engine = _engine, delegate = _delegate ...
I am writing a simple application for an artist who wants to market his work on iTunes. Because there are only twelve images, which can be deleted more rapidly than they could be selected from an image picker, the user does not select the images individually. Instead, the images are copied programmatically from the application bundle in...

After I've upgraded to Snow Leopard and Xcode 3.2, everything was screwed up. It took a while for me to figure out the whole evil was that my old Xcode installation was not really "updated", but replaced. So just everything was gone. All SDKs, Settings, everything. So Code Sense did not work because of no SDK available, and all the othe...

So after a lot of old fashioned comment-out-debugging to narrow down a leak in instruments. The leak occurs when I push a new TableViewController onto the stack. I found that I'm getting a leak from this code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellI...
For some reason after updating to Snow Leopard, my Xcode 3.2 is stupid like a toast. I had all iPhone SDK's, tons of Gigabytes of data. All is gone to deep toilet. And now I start downloading all that stuff again. Is there maybe some little hope that all those SDK's are still on my mac, somewhere? Where? Or must I really re-download and ...
After my upgrade to Snow Leopard and Xcode 3.2 (which I really regret a lot!!), Xcode lost all the SDK's. I'm one of those old-fashioned idiots who still want to develop for 2.2.1. But Apple does not offer me an old SDK download. Now I was clever and made tons of time machine backups. But: What's the preferred way to get iPhone SDK 2.2....
