Hi: I want to redirect stdout to a NSTextView. Could this also work with outputs of subprocesses? What might be the best way to achieve this?
EDIT:
According to Peter Hosey answer I implemented the following. But I do not get a notification. What am I doing wrong?
NSPipe *pipe = [NSPipe pipe];
NSFileHandle *pipeHandle = [pipe f...

Hi, I'm looking for some guidance on the best way to implement stock ticker style right-to-left scrolling of CALayers in Core Animation on OSX. I'm pretty new to Cocoa and don't know the best way to implement this.
I have a continuous stream of news items and stock details that I turn into CALayers (made up of 1 image and a CATextLayer...
Consider this code:

I have a view that contains two NSTextFieldCells. The size at which these cells are drawn is derived from the size of the view, and I want the text in each cell to be the largest that will fit in the derived size of the cell. Here's what I have, which doesn't set the font size:

Hello,
I'am currently migrating an iphone application using SQLite to CoreData.
I need to do an INSERT or REPLACE to add only the new content, is there a way to do this or do I have to fetch all the DB and look for existing objects and add the new ones ?
Thanks.

I am a little confused by this snippet of code (presented in the CocoaFundamentals guide) that overrides some of the methods when creating a singleton instance.
static id sharedReactor = nil;
+(id)sharedInstance {
if(sharedReactor == nil) sharedReactor = [[super allocWithZone:NULL] init];
return sharedReactor;
}
.

Does anyone have any preferences or comments about using either ...

OR:

Hi,
I'm having troubles releasing objects.. To explain it better I have included my code below.

[task setStandardError: pipe];
[grep setStandardInput: pipe];
[pipe release];
pipe = [NSPipe new];
[grep setStandardOutput: pipe];

The Apple documentation claims that the Core Animation action key kCAOnOrderOut has one sole purpose: to animate a layer out of sight when it either becomes hidden or has -removeFromSuperlayer called on it. I'm only referring to the latter case in this question.
In practice, when -removeFromSuperlayer is called, the layer is removed imm...
Hi everyone,
I have a Core Data entity which needs a gender property. I just need one of two, the standard male or female values. What's the best practice for this in Core Data?
In the .NET world with databases I would've created a Gender table, with foreign key in the child table. I'm still getting my head around Core Data right now -...
Hi, I'm trying to make use of CALayers to create a 3D style effect in one of my applications. However, it seems that nested CALayers do not have perspective applied to them.
To illustrate with pseudo-code, if I have a layer with perspective applied like so:
CATransform3D subLayerTransform = CATransform3DIdentity;
/* set perspective */...
Or has this been abandoned? I can't seem to find a modern sample project. I haven't been able to make any the old code I find work. I just want to write a simple Mac app that accesses an external MySQL database that's also involved in a PHP website.

I'm pretty sure i've seen this somewhere (not counting the help menu), and I feel like you could just drag one in under ib in leopard. Not that it matters, but it will either go into a dock menu or a service. Thanks

Let's say I want to write a simple Cocoa app to make the Spaces feature of Leopard more useful. I would like to configure each space to have, say, different
*screen resolutions
*keyboard layouts
*volume (for audio)
So there are two parts to my question: 1) I suppose there are ways to modify these three things independently of Spaces, r...
