I had a problem originally getting things to work with a split screen view on the iPad. The main reason was due to the fact that I was porting over code and didn’t quite know yet how it would all … Continue reading →

Delicious Library and Me

Posted on October 5, 2010 by diziet

I’ve been cataloguing a lot of stuff that I have with a view to selling it. Having got the new mac I checked to see if my code for delicious library still worked, which it did. Since then I’ve realised … Continue reading →

Following on from dynamic clocks.

Posted on August 26, 2010 by diziet

It would also be nice to draw multiple clocks if one is ‘full’ it starts another. This example draws and returns a maximum of three clocks but always returns a 90×30 image: – (UIImage *)drawClocks:(NSNumber *)time { UIImage *image; int … Continue reading →

Drawing little clock icons dynamically.

Posted on August 26, 2010 by diziet

It’s kind of nice to be able to dynamically draw little ‘clock’ time icons. This function returns a UIImage of 30×30 pixels containing such an image: static inline float radians(double degrees) { return (degrees * M_PI) / 180; } – … Continue reading →

The method of animating the appearance of views in Cocoa is good and simple I think. You can use an inbuilt one, which just works, or you can start an animation block and effectively program in key frames. To make … Continue reading →

So so close.

Just two bugs away, probably, from having something working in its entirety. E.g. everything else is additional features rather than core functionality. Current bugs: 1 – Render of StepTableCell is outside the bounds of the cell for reasons unknown, it’s … Continue reading →

A few inconsistencies in approach…

Posted on August 14, 2010 by diziet

Knocked this up today as I figure it will prove it’s worth in the future. Drag and drop an image onto it and it will generate the necessary files for the various icons/artwork an iPhone/iPhone4 or iPad application, it should … Continue reading →

A summary of the day.

Posted on August 12, 2010 by diziet

Good day.  Silly exc_bad_access bug resolved.  A macro in gdb to print the retainCount (mentioned in a previously posted link) is indeed very handy.  Spamming this through the code was also useful: NSLog(@”%@ <nameoffunction>”,self);   <— (or with another %@ … Continue reading →
