I might do both, although I can not do a "tap here" instruction if the Add button is not visible at launch. Have to create another way for that initial item to become alive. Thanks for your thoughts. [[[Brainchild alloc] initWithName:@"Richard Altenburg"] saysBestRegards]; Op 19 sep. 2012, om

Best practice when opening a Master-Detail app with no data in it yet

I am creating a master-detail app for both iPad and iPhone families of devices. For the iPad I use a split view controller and for the iPhone I use the standard drill-down interface (a table view when selected pushes the detail view onto the screen). Now it feels kind of awkward when a user fir

Re: Core Graphics optimisation

You have no time to watch WWDC 2012 presentations and like to avoid OpenGL ES as an alternative, how on earth are you going to write a fast app with thousands of drawings on a device with (in worst case) 256 MB of internal memory? I am not sure OpenGL ES will help, and one session from WWDC will

Thank you Aaron and Julius for pointing out it is a known bug. I can not check the developer forums as I am not on a developer program just yet. I should have checked by searching on the web, sorry that this time I poured my problem right into the mailing list. As this is a known bug, Apple won

Is it 'normal' that scrolling in a UIScrollView leaks some bytes?

I can answer it myself: no, it should not be considered normal that an app leaks memory, and that is why it makes me quite nervous. What happens is this: In an iPad / iPhone project I present a few UIImageViews on-screen. They are contained within their own UIScrollViews as I want to zoom in an

Re: do you init your instance variables in init method or outside the class?

If you create a new instance of a class, all its instance variables are zero, so any pointers to objects like strings and arrays are zero as well, they are there but do not point to anything. The instantiation does not automatically create those objects as well for you, you are responsible. You

Re: Modal event processing

Fritz Anderson's comments are very important, in that you do not control the state of your animation in the drawRect: but instead handle that from a calling method (like the one in your controller which is called from your timer). drawRect: is not fully under your control nor should you try to d

Re: Modal event processing

In a situation similar to yours, I ended up replacing the NSTimer with an NSAnimation. The animation I was doing was way faster after this tiny change, plus the user interface was not blocked at all. I refresh my animation 30 times per second now without any negative effect for the user. I think

Thanks for your thoughts, Charles. No, I did not copy the .xib to a new project. I created a new project for iOS wit one view, and created a new class in it that is to be a subclass of UIView which will contain my drawing code in drawRect. I copied code from the old project over into the new pr

(You may reply in Caps Lock if this question is too noobish for this list) I wrote an experimental project for Mac OS X. It uses a custom NSView and some user interface controls connected to the view's class in Interface Builder. I want to do about the same project for iOS, so I started a new pr

Re: Base64 encoding of NSImage

If you want to be sure which one works for you, it is probably best to read how Base64 encoding actually works, maybe you find out you can just as easily roll your own solution. Especially on a fast Mac desktop, it would not have to be the worlds' most efficient solution, it will be fast anyways
