The Z stands for GMT timezone //The 0901 is 09h 01m on a 24 hour clock not 12. //As long as I can get the hours/min & date from the string I can deal with the time zone later NSDateForma...

Hi Apologies if this is a dumb question but I'm trying to format a currency value for my iphone app and am struggling to left-justify the currency symbol, but right-justify the value. So, "$123.45" is formatted as (say) $ 123.45 depending on format-width. This is a kind of accounting format (I think). I've tried various methods with...

The question is simple: is there a way to use for example CABasicAnimation to animate a property on an object that's not a ´CALayer´? (Say, the ´volume´ property on an ´AVAudioPlayer´.) If not, is there a way to make it work other tha...
