ios - Distinguish a UIButton by tag -


i've got game board (an 8x8 array). want implement drawing function, each cell in board uibutton separate tag (from 0 63). how through buttons (button separate tags) being able use setimage() function?

a piece of code: 

for in 0..<8 {     j in 0..<8{         if gameboard[i,j].rawvalue == 1 {             cellbutton.setimage(uiimage(named:"whitepiece.png"), for: uicontrolstate())         } else if (gameboard[i,j].rawvalue == 2){             cellbutton.setimage(uiimage(named:"blackpiece.png"), for: uicontrolstate())         }     } }

the code posted doesn't make sense. looks have instance variable cellbutton, , you're trying use somehow set image on 64 of buttons. can't possibly work. if have tags on buttons use this:

say define tag numbers being in range 100 188, 10's digit row number , 1s digit column number:

for in 0..<8 {     j in 0..<8{         //create tag number cell         let tagnumber = 100 + * 10 + j         guard let acellbutton = view.viewwithtag(tagnumber) as? uibutton else {           print("error. can't find button tag \(tagnumber)")           continue         }         if gameboard[i,j].rawvalue == 1 {             acellbutton.setimage(uiimage(named:"whitepiece.png"), for: .normal)         } else if (gameboard[i,j].rawvalue == 2){             acellbutton.setimage(uiimage(named:"blackpiece.png"), for: .normal)         }     } }
