iphone novice developers some small problems we seek help ^ ^ ~

Done before android development, now just beginning to learn iphone, so hard to solve some of the problems encountered ⋯ thank you help us to see

Question 1, I used UIScrollview wrote a horizontal layout, a total of 40 buttons, and now I want to achieve the selected center. . But wood has ideas
Question 2, I have a UIButton, click to enlarge centered and want to achieve a pop-up animation, this is not the only change UIButton's CGRectMake, then click again to reset it CGRectMake let him back into place, there is no other way to do that (as well as animation how to achieve it)?
Question 3, iphone inside set up automatic reminders (like alarm clock) method should be how to achieve it? (Such as the user is set at 5:00 on March 10th, 2012 an alarm, then the time will have custom music reminded)

Thank you

1, UIScrollview the delegate corresponding function
2, casually looking for a book, see the section will be to understand the movie. The easiest way is to set the picture + system animation.
3, Push (local).

Yes, use local push. (Push server settings in the machine, and do not control their implementation details.)
