I can post code, though I'm not quite sure where to start. I have a UITableView with custom cells, in the middle tier of a three-level UINavigationView scheme. When I drill down to the bottom level and see details about my data, then use the top-left back button, my table view comes back scrolled all the way to the top, rather than scrol...

A quick question, I am setting a delegate for UITableView and I have a question regarding setting the delegate and dataSource properties. I have noticed that the properties for delegate and dataSource are not available, I was thinking that adopting the protocols would make them available. But I am now thinking that I maybe have the supe...
Well, may be this question is silly, but I couldn't find a way (except programmatically). I built a project (for iPhone OS 3.0) which uses Core Data. The xcdatamodel file shows the schema description, but I want to see the data in tabular form (like the management studio for mssql server or phpmyadmin for mysql). Is there any way (excep...

I used reloadData right after the call to the picker, but the code is executed before I do "Done" on the picker. Some idea? Thank u ...
I am no graphics expert but I somehow managed to make some good looking custom grouped UITableViewCells by setting the background view to a backgroundView with some CG code. In all SDK's up to 3.1.3 (maybe 3.2... I haven't tested on the iPad) this was working great, but I think a more recent SDK has introduced a change in the way graphic...

The user will type in measurements in the 2 TextFields. When they hit the button the label displays the volume of the measured object in Gallons. That...

Does anyone know of a way to add additional attribute types to the @property keyword without modifying the compiler? Or can anyone think of another way to genericize getter/setter creation? Basically, I have a lot of cases in a recent project where it's handy for objects to lazily instantiate their array properties. This is because we...

I would also like to detect the case when the user is connected over WIFI and suddenly received 3G signal. In other words, I would like to be asynchronously notified of netw...
