so i'm trying program ios app in swift, there splash screen before tab bar screen. i've looked @ both: http://sweettutos.com/2014/01/08/present-a-login-screen-before-the-tab-bar-controller-in-a-uitabbarcontroller-based-app/ and loading welcome screen(splash screen) before tabbarcontroller but both of them require nib file , did ui in storyboard. here's main question: code on website has this: controllername(nibname: "nibname", bundle: nil); is there way same thing without nib file , use storyboard? thanks in advance! assuming have tabbarcontroller in storyboard, add view controller next it. then click on new view, , in attributes inspector, check off "is initial view controller". that makes new view first thing comes when app opened. go tabbarcontroller, have button on first view has segue(control drag) tabbarcontroller .

i have use case need add pagination inputs (viz. page number , page size) existing service calls (that returns list of results) without changing existing signature (because break existing clients). 1 way of achieving set inputs in threadlocal , have implementation read threadlocal , pagination logic. code point of view, like: try { paginationkit.setpaginationinput(pagesize, pagenumber); // set threadlocal list<specialobject> results = specialservice.getspecialobjs(); //results count equal pagesize value } { paginationkit.clearpaginationinput(); // clear threadlocal } from client's point of view, not @ elegant , wanted wrap functionality better syntactic sugar. there 2 approaches had in mind , wanted know if generic enough use case has been solved pattern elsewhere. there many such services , trying put decorator each of services not desirable. approach 1: mockito style of mockito.when(methodcall).thenreturn(result) kind of sugar. code may like: speci...
