ios - How to change color for tab bar non selected icon in swift? -

how change color tab bar non selected icon , text? found answer (how change inactive icon/text color on tab bar?), can't implement swift.

the below sets defaults uitabbaritem's, can add appdelegate. change text color.

uitabbaritem.appearance().settitletextattributes({nsforegroundcolorattributename: uicolor.blackcolor()}, forstate:.selected) uitabbaritem.appearance().settitletextattributes({nsforegroundcolorattributename: uicolor.whitecolor()}, forstate:.normal) 

for changing icon' color can either set image given state image have color.

self.tabbaritem.selectedimage = [[uiimage imagenamed:@"selectedimage"] imagewithrenderingmode:uiimagerenderingmodealwaysoriginal];  self.tabbaritem.image = [[uiimage imagenamed:@"notselectedimage"]  imagewithrenderingmode:uiimagerenderingmodealwaysoriginal]; 

or can way :

add extension uiimage class (from this answer) :

extension uiimage { func imagewithcolor(color1: uicolor) -> uiimage {     uigraphicsbeginimagecontextwithoptions(self.size, false, self.scale)      let context = uigraphicsgetcurrentcontext() cgcontextref     cgcontexttranslatectm(context, 0, self.size.height)     cgcontextscalectm(context, 1.0, -1.0);     cgcontextsetblendmode(context, kcgblendmodenormal)      let rect = cgrectmake(0, 0, self.size.width, self.size.height) cgrect     cgcontextcliptomask(context, rect, self.cgimage)     color1.setfill()     cgcontextfillrect(context, rect)      let newimage = uigraphicsgetimagefromcurrentimagecontext() uiimage     uigraphicsendimagecontext()      return newimage } } 

and in viewdidload :

for item in self.tabbar.items [uitabbaritem] {     if let image = item.image {         item.image = image.imagewithcolor(uicolor.blackcolor()).imagewithrenderingmode(.alwaysoriginal)     } }
