Car park timer is inspired by people around me always got city council tickets, just because of forget to go back the car. It basically created 4 custom buttons, which are the most common parking limit time. It lets user start counting down by one click, thus avoid the textfield input or datepicker input that has to touch multiple times by just select the right time.
It was suppose to have two views, second view is a custom time picker that only generate all the other rare parking time limit. However that is the hardest part to do it for me. I get how to get the picker generating text, but couldn't worked out link the timer with the text respectively. One more issue is that the time instance. The timer runs faster as click different buttons.
I do think I lack of foundation knowledge of C and Objective C. When I looked up iphone SDK forum, there are lots of people help out other people figure what their issue are. Mostly not even give the code, just simply by demonstrate the concept.
