Re: How to show progress indicator for background job

Hi Ron, Thanks for that... I should have thought to check out how Apple did it themselves. I was thinking a status message would be ok, but wasn't sure about the progress bar, but then it could all be handled in a text label anyway... "Downloading update... 10% complete". Gant On 17/01/2010

[iphone] Release Navigation View Controller Question

Hi, I have Navigation based application. When I switch from one view to the next I use the following code. In the below code, is it ok to release "browseviewController"? BrowseViewController *browseviewController = [[BrowseViewController alloc] initWithNibName:@"BrowseViewController" bundle:

Re: [iphone] Release Navigation View Controller Question

Yes, that code is 100% fine. Here's the logic from purely your point of view. You allocate browserviewController and in doing so take ownership. You do some stuff with browserviewController. You are finished with browserviewController, and don't want to do anything else with it, so you resign own

Dave, If you are setting up NSURLConnection on an NSOperation, I would suggest you keep the operation around as you get the data back. The symptom you describe, sounds like you are starting the NSURLConnection, but then you leave your main method in the NSOperation you created. This essentia

Re: NSURLRequest and NSOperationQueue

Thanks for the responses! It hadn't occurred to me to spin the runloop myself. My main reason for using an NSOperationQueue for the connections was because the spawner of the connections was also the connection delegate, and it would've taken some interesting code dancing to handle the delegate

Re: NSURLRequest and NSOperationQueue

The issue that Dave has run into is that when you call the asynchronous NSURLConnection call, NSURLConnection looks to see what thread you are calling it on, and it will only call your delegate back on that Thread (if it exists). If you exit your NSOperation main method, your thread is going to

Bindings: NSMutableArray -> NSArrayController -> NSPopUp

I am struggling with bindings. I have worked through the examples in the Hillegass book, but it seems that none of the examples using NSPopUp quite matches what I need. In my app, just before a view appears, it gets handed a list of games in an NSMutableArray. It makes the array available with

Re: If Array Controller is empty, how to populate pop-up list?

Hi Ken, Thanks for your tips. We're closer I think. I took off the Selected Index binding and instead bound the Selected Value to ArrayController-selection-name. I'm probably binding it wrong though, because I haven't quite gotten it to work yet. I think what you say makes sense, about the select

Screen saver using Asynchronous IO lags at close

I am writing a screen saver that forks a process and reads its stdout chunk by chunk. Since I didn't want it to block on reads, I tried to find the non-blocking IO parts of Cocoa. I found Cocoa's NSNotificationCenter, and the associated methods with the NSFileHandle class, and that seemed to f
