ios - How can I maintain relative scrolling position within a UIScrollView during a UISnapBehavior animation? -

i using uidynamicanimator's uisnapbehavior animate these circles between 2 states: http://cl.ly/image/1g3p1b2x2v14/image%202013.09.24%2011%3a35%3a43%20am.png that works great. however, put inside uiscrollview. when scroll before uisnapbehavior animation has "settled" (there seems delay after looks finishes , when finishes), circles lose relative positioning scroll container: http://cl.ly/image/1e0i3l460j1v/image%202013.09.24%2011%3a32%3a10%20am.png when scroll after waiting few seconds after animation has "settled", circles not lose relative positioning i'm assuming because uisnapbehavior animates things fixed positions, , reverts relative positioning after finishes, i'm not sure if that's true. i setting uidynamicanimator on uiview containing uiscrollview. setting uidynamicanimator initwithtarget uiscrollview seems have fixed it.

Java: pre-,postfix operator precedences -

-
i have 2 similar questions operator precedences in java. first one: int x = 10; system.out.println(x++ * ++x * x++); //it prints 1440 according oracle tutorial : postfix (expr++, expr--) operators have higher precedence prefix (++expr, --expr) so, suppose evaluation order: 1) first postfix operator: x++ 1.a) x++ "replaced" 10 1.b) x incremented one: 10+1=11 @ step should like: system.out.println(10 * ++x * x++), x = 11; 2) second postfix operator: x++ 2.a) x++ "replaced" 11 2.b) x incremented one: 11+1=12 @ step should like: system.out.println(10 * ++x * 11), x = 12; 3) prefix operator: ++x 3.a) x incremented one: 12+1=13 3.b) ++x "replaced" 13 @ step should like: system.out.println(10 * 13 * 11), x = 13; 4) evaluating 10*13 = 130, 130*11 = 1430. but java seems ignore pre/post ordering , puts them on 1 level. real order: x++ -> ++x -> x++ what causes answer (10 * 12 * 12) = 1440. second one...
