Hi all, I am developing an iphone app, there's a section in it where user can declare his task and its occurence in time. I.e. recursive task. The task will only show an alert box and nothing else when its due time. Its a kind of reminder, rather than a real task scheduler. What's the best way or technology to achieve that with objecti...
I may just be passing data between views completely wrong here, so I am open to completely changing how I pass my data back and forth. My app delegate creates the NSManagedObjectContext and passes that to my main menu using a UINavigationController which makes it the root view: MainMenuViewController *mainMenuViewController = [[MainMen...
I've got quite a few UIView-based Animations going on most of the time in my app. I want to be able to handle all device rotations, but it's always a performance hit when you trigger the device rotation when there's already an animation going on. I wonder what's the best practice for cases like this? Shall I subclass all my UIView elem...

Any ideas of what else could one do to get it to terminate? Perhaps ...

Hey, I've been reading about the Apple withholding a 30% tax on the revenue until you fill out a W8BEN tax form. This isn't very well documented and as I've only just read about this, I'm starting to think I'm going to lose out on my previous sales. If you're from the UK (like me) and are a sole trader, how do you go about avoiding thi...

I've got an iPhone app that's location aware (well, I'd LIKE it to be! ;) but, for some reason, the location notifications never fire. I'm pretty good with iPhone SDK (30+ yrs dev, iPhone since day-1), and I thought I followed all of the documentation and samples to set everything up correctly. However, when I set it to notify when I e...

Hi, I have view 'A' which has a number of textfields. Pressing a button on view 'A' brings up view 'B' (with a picker to select multiple data). On close, view 'B' disappears and viola, the textfields are populated. This should be straight forward solution but I can't seem to get my head around the problem - how do you reference the tex...
