NSHost and NSStream question

Hi Cocoa developers, I am writing a small application that acts as a TCP client for another application (TCP server). The client nows the IP address and port of the server. I then use NSStream to create an output stream from an NSHost (see code bellow). If I initialize the IP address as 127.0.

Re: NSHost and NSStream question

Hi, I finally fixed my problem. The server was not opening the port properly, so the client could not connect. It as error 61 of POSIX domain. Seems to work fine now. Thanks, Mathieu On 2010-01-21, at 4:37 PM, Jens Alfke wrote: > > On Jan 21, 2010, at 6:43 AM, Mathieu Coursolle

Layer-backed view issue with isOpaque

Hi Cocoa developers, I have a small application that consists of a NSTabView, in which all tabs contain a single custom NSView. That custom view is layer-backed (setWantsLayer:YES in awakeFromNib). So far, the view layer doesn't draw anything, and the NSView drawRect method fills its content

NSInputStream Overflow?

Changing tab in NSTabView with wantsLayer and Garbage collection problem.

Hi Cocoa dev, I would like to use core animation in an application, so I am investigation on how to use the wantsLayer property of an NSView, but I got confused with some behavior so far... I created a simple window, in which there is a tab view. In the first tab, I added a custom view, a

Removing subviews that are layer backed problem.

Hi Cocoa developers, I have a custom view (let's call this one the main view) which shows some UI controls and another custom subview which is layer backed (wantsLayer = YES). I created my own CAOpenGLLayer subclass to perform specific OpenGL drawing in it. The main view needs to change i

Re: Endless Hang on Saving a Core Data Document

Hi, We have a Core Data/ Leopard/Garbage collection/SQLite application that is never returning from save. I found your post, and changing to XML did solve the issue. Is there a rdar for this? We do have a 100% repro case, and we'd like to use SQLite... Thanks! Mathieu On 28-Feb-08, at
