I am working on a regular iPhone app which pulls data from a server (XML, JSON, etc...), and I'm wondering what is the best way to implement synching data. Criteria are speed (less network data exchange), robustness (data recovery in case update fails), offline access and flexibility (adaptable when the structure of the database changes ...
From the Core Data docs: A property name cannot be the same as any no-parameter method name of NSObject or NSManagedObject—for example, you cannot give a property the name “description” Ok, so -description is blocked for property names. I guess it's because of KVC. But what exactly does "no-parameter" mean? Is that any meth...

I'm developing a map application for both iPhone OS and OS X. This uses Core Graphics to render a map, but rendering each frame is too slow to scroll in 60fps, and consumes the battery. So I want to cache the map with rendering the map on bitmap tiles(256x256), but what kind of bitmap should I use? (like CGImage) ...

I have a view with a table on it. When the app starts, it loads the first 5 visble cells. That works as expected. My problem is that, when I try to scroll down in the table the app crashes with this error. What I've found is that didSelectRowAtIndexPath is not being called. AFAIK, all I need to do is to subscribe to the delegate. But I...
After reading this thread: http://stackoverflow.com/questions/2792932/nsuserdefaults-not-present-on-first-run-on-simulator I know it's quite easy to store some app data in the [NSUserDefaults standardUserDefaults]. But if other applications also happen to use the same key to store their data, is this possible that my app data gets overw...
For example, I make a fullName property and set it to transient. Does it matter what data type that property is, in this case? For example, does it matter if it's set to int or string? As far as I get it, a transient property is almost "ignored" by Core Data. I make my accessors for that and when someone accesses fullName, I simply cons...

I see NSInteger is used quite often and the typedef for it on the iPhone is a long, so technically I could use it when I am expect int(64) values. But should I be more explicit and use something like int64_t or long directly? What would be the downside of just using long? ...
