This presentation covers the basics of Auto-layout on iOS and how to handle some situations such as animations or self-sizing cells.

1. AUTO-L
Porque é im

2. AUTO-LAYOUT
Porque é importante

3. Autoresizing Mask

6. CONSTRAINTS

8. POSIÇÃO

9. ACHO QUEVAI DARTUDO CERTO
HMM… ATÉ ROLA, MAS "DAQUELE JEITO"
OK, CAIU A CASA!

14. SELF-SIZING CELLS

15. return 100
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
{

16. }
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
{

17. tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 44.0

22. SCROLL-VIEW & AUTO-LAYOUT

23. “THE CONSTRAINTS ON THE SUBVIEWS OF THE SCROLL VIEW MUST
RESULT IN A SIZE TO FILL,WHICH IS THEN INTERPRETED AS THE CONTENT
SIZE OF THE SCROLL VIEW. (THIS SHOULD NOT BE CONFUSED WITH THE
INTRINSICCONTENTSIZE METHOD USED FOR AUTO LAYOUT.)”

25. [UIView animateWithDuration:1 animations:^{
myView.frame = newFrame;
}];
// update constraints
[UIView animateWithDuration:1 animations:^{
[myView layoutIfNeeded];
}];
