i've created 1 tab bar bottom view proportional height related main superview. whereas, tab bar bottom view height in 6+ -> 59, in 6 -> 53, in 5 -> 45 & in 4s -> 38. it's working proportionally fine. if want tab bar view's height should minimum 46, @ maximum should work proportionally. so based on above heights on different devices, want achieve 6+ -> 59, 6 -> 53, 5 -> 46 & in 4s -> 46. so possible solution in auto layout achieve this. in advance. you should add height constraint more 46 , priority 1000.and set priority of top space constraint 750.

i've learned cannot: take address of undefined function take address of templatized function type fail compile for but i've learned can call decltype return type of said function so undefined function: int foo(char, short); i'd know if there's way can match parameter types types in tuple . meta programming question. i'm shooting decltypeargs in example: enable_if_t<is_same_v<tuple<char, short>, decltypeargs<foo>>, int> bar; can me understand how decltypeargs crafted? for non-overloaded functions, pointers functions, , pointers member functions, doing decltype(function) gives type of function in unevaluated context, , type contains arguments. so the argument types tuple, need lot of specializations: // primary function objects template <class t> struct function_args : function_args<decltype(&t::operator()> { }; // normal function template <class r, class... args> struct function_arg

when programming in java practically always, out of habit, write this: public list<string> foo() { return new arraylist<string>(); } most of time without thinking it. now, question is: should always specify interface return type? or advisable use actual implementation of interface, , if so, under circumstances? it obvious using interface has lot of advantages (that's why it's there). in cases doesn't matter concrete implementation used library function. maybe there cases matter. instance, if know access data in list randomly, linkedlist bad. if library function returns interface, don't know. on safe side might need copy list explicitly on arraylist : list bar = foo(); list mylist = bar instanceof linkedlist ? new arraylist(bar) : bar; but seems horrible , coworkers lynch me in cafeteria. , rightfully so. what guys think? guidelines, when tend towards abstract solution, , when reveal details of implementation potential performance gains?
