Hi, I have a CoreData model in my iPhone app, which is linked to a SQL Database with more than 50k records. When I generate the records classes, Xcode uses the @dynamic directive for properties. I have a property named "ISFAV", NSNumber type (CoreData does not use BOOL or Integer, it uses object types). Being short, I change the ISFAV pr...

I used Apple's PageControl example as a model, but am creating the scrollview myself in a View. 1) The scrollview works as expected when loading in default Portrait, scrolling left to right horizontally 2) Out of the box, when rotating CW and reinitializ...

I'm trying to display an UIImageView within a tab on an iPad. I hide the tab bar and I want the UIImageView to take up the entire screen, ie be full screen. I try resizing everything in sight and the image will not occupy the space used by the tab bar. I've tried debugging, printing the frame for each view going up the view hierarchy. Ev...
I need an equivalent to C's pow() function that will work with NSDecimalNumbers. With pow you can use negative numbers e.g. pow(1514,-1234), with NSDecimal's decimalNumberByRaisingToPower: method, you are forced to use an NSUInteger which seems to require a positive value. I'd like to be able to do something like this: [decimalNumber d...

There seem to be lots of answers for cross-platform frameworks for devices (iPhone + Android), and cross-platform frameworks for desktops (Mac + Win + Linux). This is a different question regarding a suitable framework, methodology, template app, tutorial, or just helpful hints, on developing native apps (not just web apps) that are cro...

The workaround would be to force-close all outstanding connections at a certain point. Can I do this somehow with NSURLConnection, i.e. some...

Now I realized that I want to have a relationship to another entity (Aisle). There is already a one-to-o...
