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 - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
