4 iphone game development issues

1 is to draw a rectangle, and then add a picture, then this figure can move up a little, like Landlords cards, point he bounced

4 can not load a bitmap? How to add. What function by adding

2 how to call the system API
For example CGxxx xxx;
- (Void) fn {xxx;}
How not achieve

3 how to use class types such as
@ Interface XXX
@ Class XXX pt;
@ End
Then create a function - (void) fn {pt;}
Directly so good?
