Problem getting correct file URL in NSTask process

Hi, I have a daemon that spawns NSTasks on request. A task is passed a number of paths to process. These paths are pased correctly to the task, and in the task I can correctly extract the path string from optarg. When I try to turn the path into a file url however, the resulting URL is not corr

Logging in ad-hoc builds

Hi, I have a problem with NSURLConnection in my ad-hoc build and I'd like to log the problematic url. In debug version i can just output it to console. The question is how do i track it in ad-hoc? It's not about crashing, so crash logs will not help. Any ideas? Thanks in advance Nava Carmo

Ad hoc. Are you talking about iPhone development? If so then log it to the console and grab the console logs afterwards through Xcode. Remember to take all that stuff out at the end, no point carrying all that log in your phone. On 27-May-2010, at 19:57, Nava Carmon wrote: Hi, I have

Adding to what others have said. 1. Determine a list of applications that can work with the file type. Use Launch Services (LSGetApplicationURLs for URLs). 2. In the your open panel delegate, implement: shouldEnableURL and return YES if the application is on the list 3. You may also have an ap

If a window is ordered out, AppKit will not order it back in when the app is activated. Is it possible that a different window is created, or that the window was not ordered out to begin with? I'm confused when you say that an ordered-out window is the key window. That should not be possible.

Thanks for the link Ken, though confusion still persists. Seems to be saying don't use -setFlipped: unless you really know what you're doing. That concurs with your own advice about not using setFlipped unless you're locking focus on the image to get a flipped context for drawing. I'm not, sinc
