ios - How to make simple UITabBarController in Swift? -

-

i created uitabbarcontroller class

i created 2 view controllers , set title property each one

i want change size , color of text label within tabs

i set tab color , frame using

uitabbar.appearance().bartintcolor = uicolor.bluecolor()  tabbar.frame = cgrectmake(0, 0, view.frame.width, 100)

now adjusting tabs, tried each of following

uitabbaritem.appearance().settitletextattributes(nsdictionary(object: uicolor.whitecolor(), forkey: nsforegroundcolorattributename), forstate: uicontrolstate.normal)

that changed text color white

uitabbaritem.appearance().settitletextattributes(nsdictionary(object: uicolor.whitecolor(), forkey: nsforegroundcolorattributename), forstate: uicontrolstate.normal)  uitabbaritem.appearance().settitletextattributes(nsdictionary(object: uifont(name: "helvetica", size: 16.0)!, forkey: nsfontattributename), forstate: uicontrolstate.normal)

that changed size of text, not color !

uitabbaritem.appearance().settitletextattributes(nsdictionary(objects: [nsforegroundcolorattributename, nsfontattributename], forkeys: [uicolor.whitecolor(), uifont(name: "helvetica", size: 16.0)!]), forstate: uicontrolstate.normal)  // or  var attributes = nsdictionary(objects: [nsforegroundcolorattributename, nsfontattributename], forkeys: [uicolor.whitecolor(), uifont(name: "helvetica", size: 16.0)!])  uitabbaritem.appearance().settitletextattributes(attributes, forstate: uicontrolstate.normal)

that last bit did nothing @ all, neither setting color nor size of tabs text

update------

to more precise, above code tried within uitabbarcontroller child class in viewwillappear

furthermore, curious how make whole tabs (tab-able) , not text label part of it, , add sort of line separator between tabs

i found out how make happen

setting title color , size has go through uitabbaritem appearance "proxy"

override func viewwilllayoutsubviews() {      self.tabbar.frame = cgrectmake(0, 20, view.frame.width, 50)      var font = uifont(name: "helvetica", size: 16)      var objs = nsarray(objects: font!, uicolor.whitecolor())      var keys = nsarray(objects: nsfontattributename, nsforegroundcolorattributename)      uitabbaritem.appearance().settitletextattributes(nsdictionary(objects: objs, forkeys: keys), forstate: uicontrolstate.normal) }
