i have uiview user can add subviews to. need application automatically place subview user @ first found open location. a location considered open if frame of subview placed not intersect other subviews. the calculation locate open area not need instant - run when user first enters scene, @ point saves location if user placed it. the container uiview large enough have open space place subview (there limited number of subviews user can add). what simplest way determine location place subview? i posted description of algorithm commonly used solve these sorts of problems in answer question: finding largest rectangle in 2d array . it's easy adapt solution problem. in question filled spaces on grid, made determining amount advance scan line little easier, have more careful. other question looking empty rectangle maximal area, can exit algorithm find first fit. of course, if subviews same size, solutions identical. hope helps.

i have coredata model backed sqllite db. want populate db initial data. i have been using python far , has been working well. bit isn't working inserting dates. understand coredata stores dates in epoch format inserting them via python this: time.mktime(datetime(2012, 7, 1, 12, 30, 30).timetuple()) however, doesn't give me correct date when data loaded via coredata. ideas on how format date read in correctly via coredata? *note: realise people recommend doing via small app uses same model rather using python script, find python syntax more concise constructing , inserting lots of objects. e.g. can call methods insert data this: insertdata(con, 1, 1, 'data 1', 'description') vs objective-c long-winded method calls: [self insertdata withcon:con id: 1 i2:1 val:@"data 1", desc:@"description"]; core data appears use 1 january 2001, gmt reference date (same nsdate method timeintervalsincereferencedate ) , not 1970, mktime function i...

i have android project includes 2 android library projects. i'm using command ant debug build project , takes around 1min , 20sec. i've counted 17 seconds used compile first android library project , 42 seconds used compile second android library project. since these 2 dependency projects updated it's not necessary compile them each time. how can avoid ant compiling 2 android library projects each build? add dont.do.deps=1 local.properties (or pass property ant other way)

i'm practicing using mulitple files , header files etc. have project takes 2 numbers , adds them. pretty simple. here files: main.cpp #include <iostream> #include "add.h" int main() { int x = readnumber(); int y = readnumber(); writeanswer(x + y); return(0); } io.cpp int readnumber() { int x; std::cout << "number: "; std::cin >> x; return x; } void writeanswer(int x) { std::cout << "answer: "; std::cout << x; } add.h #ifndef add_h_included #define add_h_included int readnumber(); void writeanswer(int x); #endif // #ifndef add_h_included the error showing in io.cpp. exact errors are: http://gyazo.com/117f407f4717ad4472f52b57b628c514.png does have idea why may happening? thanks. edit: made small project yesterday same amount of files (2 .cpp , 1.h) , didn't include iostream header in other .cpp , still compiled , ran fine. add #include <iostream> start of io.cpp too.
