Hi. I've run into a bit of an issue with NSTableView. The problem is that the table view is requesting data too early (it immediately requests the data from the controller), as in, the data is not there when the table view asks for it. Other methods, which gather the data to be shown in the table view haven't finished executing by the ...

I'm not using NSURLConnection because I want to be able to specify a proxy different from the one set in the OSX System Preferences. My problem is that I wasn't able to find any working example and the Apple documentation do not provide a working ...
I'm at my wits end. I'm trying to debug a crash, and finally I manage to track it down. My 'minutesLeft' variable is somehow being released. Problem is, I never set it to release, and the property is set to retain. I can't figure out what is going on! Using the zombie variable, I got the following message: * -[CFNumber intValue]...
Hi All, I have a map displaying multiple annotations. I'd like to mimic the behavior of the Places tab on the Photos built-in app (iOS 4), where the annotations are automatically joined together or splited apart as the user changes the zoom level. How do I do that? Thanks! ...

Then, I want to set a relationship from User to Location, from Photo to Location, etc. Should I do it without creating an inverse relationship from Location to the others? Otherwise, how would I do it like that? Thanks! Matt ...
I would like to make an application in which, when I press a button, one video starts playing, and when it finishes or when I press "done" button it should take me to a view different from the first one where I launched the video. ...

Hi guys. I have a tab bar app, created from the template. One of the views is a tableview, and when the user touches the header I have a new tableview flip over to show some new data. When the new tableview displays, it hides the tab bar. I want the table bar to be visable and active. I cant seem to work out how to do this. Any pointer...
I have a requirement to fill cells with varying length wraparound text. My current routine is handling this satisfactorily, however, I am concerned about the use of a couple of constants being used. The values 10 and 260 below represent the margin and cell width expected, but they are only accurate for standard definition resolution in...
I'm getting some strange behaviour, and I'm wondering if a root cause of that behaviour might be selectRow (used to set which row in the picker wheel should be viewed as selected) causing didSelectRow (which I thought was only used for user input) to fire. I certainly can't come up with any other reason for code that should only be in d...

For example, I have the code in C#: public abstract class AbstractBaseClass : AInterface { // methods go here } internal class InternalSubclass : Abstrac...

Also, the width should change based on if the device is portrait or landscape (for ipad). Anybody know how to do this?? I've been looking for a while... thanks! ...
Hello everyone, I just wanted to know what kind of UITableViewCell are on applications such as "Mail", and how to set one up. They seem to have much more length for extra text and other objects. A good sample project or some code/reference link would get me started. Thanks, Kevin ...
I have some UI elements that will share common parts with other UI elements. They correspond to model objects in an inheritance hierarchy. As an example let's say all Layers can be toggled on/off. All WaveLayers are Layers which additionally define a .wav filename. And there is a specific concrete subclass of WaveLayer called GroovyLaye...
