I'm trying to load a new view into an existing view controller, but I want to load that view from a xib file. My plan was to create a second viewController (viewController1 in the code below), then retain its view and release that viewController that I just created. I was hoping that the viewController would be released and the view woul...
I may very well be confusing this with the Cocoa (Mac OS X) side of things so it may not exist in Cocoa-Touch...but I thought there was a way to quickly ask a NSSet to poll its members and return a sum of say an NSInteger property in each of its objects? Closest I can find is objectEnumerator whereby I suppose I could rifle through each...
as a quick test of formatting very large, precise numbers i'm doing: (number is a synthesized NSDecimalNumber...) number = [[NSDecimalNumber alloc] initWithDecimal:[[NSDecimalNumber numberWithDouble:420000008698643507200000.0F] decimalValue]]; DLog(@"unformatted: %@", [number stringValue]); which gives me: "unformatted: 4200000086986...
If you drag down list of your notes, search bar will come down. But if you keep dragging it, search bar still stays there right below navigation bar, creating "gutter" between search bar and the first row. Any idea how to do this?

So the past two clients I've been at, all the talk has been about creating an iPhone app, and I won't lie, I want to make one. Or at least learn how to make them. I've never owned a Mac, so I have no idea how their OS functions/works/performs, whatever. I'm a .NET Developer and build my own gaming rigs at home, but as far as Mac hardw...
I am getting tricked up with arrays and nested arrays. I would like this if statement to evaluate to True if lastObject doesn'texist, or if accelerometer.x - lastObject[0] > .1 My code doesn't do this. if (![accelerometerArray lastObject] || [NSNumber numberWithDouble:acceleration.x] - [[accelerometerArray lastObject] objectAtI...
How would one go about creating a 'beat box' style sound engine, where a series of sounds can be queued up ahead of time and during playback. These sounds need to play back without any gaps or hiccups though. I've looked into OpenAL and have attempted to use the alSourceQueueBuffers() to create a source with a series of pre-buffered cl...

Essentially, I'm working on asynchronously downloading images and adding them to specific UITableView cells (twitter profile images using MGTwitterEngine from Matt Gemmell).

I'm using the method described by Josh in this question to add a toolbar to the top of the iPhone's keyboard. Basically, the idea is: Add the view controller as an observer for the notifications UIKeyboardWillShowNotification and UIKeyboardWillHideNotification in its initialization method Whenever those notifications are posted, animat...
