ios7 - iOS 7 UISearchDisplayController search bar disappears -

-

i updating app , came across issue. when start typing in search bar search bar disappears , can see table view. can still keep on typing , table view gets updated cannot see search bar. same settings works fine on ios < 7

any idea why happening ?

step 1 step 2 step 3

a little late, i've encounter same problem recently. wanted search bar visible , active through of search, dimmed view, overlaid it, big problem. me thing worked changing frame of dimmed view (apparently it's not same changing frame of searchresultstableview). i've managed following code:

-(void)setcorrectframes {     // here set frame avoid overlay     cgrect searchdisplayerframe = self.searchdisplaycontroller.searchresultstableview.superview.frame;     searchdisplayerframe.origin.y = cgrectgetmaxy(self.searchdisplaycontroller.searchbar.frame);     searchdisplayerframe.size.height -= searchdisplayerframe.origin.y;     self.searchdisplaycontroller.searchresultstableview.superview.frame = searchdisplayerframe;     }  -(void)searchdisplaycontrollerwillbeginsearch:(uisearchdisplaycontroller *)controller {     [self setcorrectframes]; }  -(void)searchdisplaycontrollerdidbeginsearch:(uisearchdisplaycontroller *)controller {     [self setcorrectframes]; }

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.
