Hi,
I hope this is not too much off topic, but my iPhone app tries to
establish a TCP connection over Wifi.
I noticed that sometimes (about 30% of the attempts), a connection is
refused. I do see an ARP request, but there is no TCP SYN packet
following after the answer. Is this a bug in iOS?
Dear list,
I have implemented an editor where I use UKKQueue to handle changes to the file
by other apps. The problem is that I don't get a notification if the file is
committed to a CVS repository (or an SVN repository, for that matter). Looking
at the file on disk, CVS does change the file

Thanks Ricky, this is a very drawing-heavy application, so I think it's
probably worth a little pain to get it mostly drawing cross platform, and then
wrap the platform specific UI around that. I'm mostly there with that approach.
Being the same refers to the size, position, rendering between

You may have better luck on the macnetworkprog list. Despite the historical

Hi Mike,
Seconding Sherm and Joar, this will be the easiest way to get started. Down the
line, if that doesn't work, have a look at Core Text.
Also, I have been developing an application for drawing with text. I draw a few
hundred individual letters at a time, then commit them to a graphics

This may not be your main problem, but you should never inspect a returned
error object
You can quickly iterate (and read) the array that way
for(NSTextField* aField in fieldsArray){
[aField doSomething];
}
So you don't need to count the items and iterate.

You could create an array of objects grouping the parameters of your strings
For example:
typedef struct
{
NSAttributedString*text; // it already contains color and font
NSPoint position;
} MyObj;
Or you can even create your own class MyObj

I’m trying to create a synchronous method on iOS (4.2.1) to create a
thumbnail image for a PowerPoint file. To accomplish this, I want to
load the file into a web view, then wait for it to load, then render
its context into a new graphics context and save it to an image.
Here’s what I have so far:
Why not just use a UIImageView instead of implementing a custom UIView subclass
to do this? If this is all you are doing a UIImageView is very often the
superior choice.

Yes, we optimized NSStringDrawing API since the documentation discouraging its
use was first written.
In fact, for some of short simple string rendering, it's the fastest on the
platform (use -drawWithRect:... variants for the maximum efficiency if
possible).
So, as already mentioned, use the

As I understood it several years ago, there was no native support in Cocoa

vertical orientation than they normally would when drawing
I am drawing some CALayers, and use code like what I have below so I can draw
exactly on pixels.
When I draw it in my CALayer drawing code, it's not always pixel aligned. It's
certainly better than if I had done no rounding, but still it is not correct.
Is there something I'm not doing right?

You need to make sure the layer is aligned correctly too. The anchor point by
