Wie platziert man die Schaltflächen in UIStackView neben anderen basierend auf Bedingung?

Question

Ich habe eine Stapelansicht, in der ich die Schaltflächen dynamisch hinzufüge. Aber ich muss die Tasten basierend auf der Bedingung wie folgt hinzufügen:

if trim.contains("0"){ 
     print("contaim 0") 
     let button1 = UIButton(frame: CGRect(x: 0, y: 0, width: 60, height: 20)) 
     button1.setTitleColor(UIColor.blackColor(), forState: .Normal) 
     button1.setTitle("No", forState: .Normal) 
     button1.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
     button1.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
     myStackview.addSubview(button1) 
    } 
    if trim.contains("1") { 
     print("contaim 1") 

     let button2 = UIButton(frame: CGRect(x: 90, y: 0, width: 60, height: 20)) 
      button2.setTitleColor(UIColor.blackColor(), forState: .Normal) 
      button2.setTitle("Less", forState: .Normal) 
      button2.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
      button2.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
      myStackview.addSubview(button2) 


    } 
    if trim.contains("2"){ 
     print("contaim 2") 

     let button3 = UIButton(frame: CGRect(x: 150, y: 0, width: 60, height: 20)) 
     button3.setTitleColor(UIColor.blackColor(), forState: .Normal) 

     button3.setTitle("Half", forState: .Normal) 
     button3.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
     button3.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
     myStackview.addSubview(button3) 
    } 
    if trim.contains("3"){ 
     print("contaim 3") 
     let button4 = UIButton(frame: CGRect(x: 210, y: 0, width: 60, height: 20)) 

     button4.setTitleColor(UIColor.blackColor(), forState: .Normal) 

     button4.setTitle("On", forState: .Normal) 
     button4.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
     button4.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
     myStackview.addSubview(button4) 
    } 
    if trim.contains("4"){ 
     print("contaim 4") 
     let button5 = UIButton(frame: CGRect(x: 270, y: 0, width: 60, height: 20)) 

     button5.setTitleColor(UIColor.blackColor(), forState: .Normal) 

     button5.setTitle("With", forState: .Normal) 
     button5.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
     button5.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
     myStackview.addSubview(button5) 
    } 
    if trim.contains("5"){ 
     print("contaim 5") 
     let button6 = UIButton(frame: CGRect(x: 310, y: 0, width: 60, height: 20)) 

     button6.setTitleColor(UIColor.blackColor(), forState: .Normal) 

     button6.setTitle("On Burger", forState: .Normal) 
     button6.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
     button6.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
     myStackview.addSubview(button6) 
    } 
    if trim.contains("6"){ 
     print("contaim 6") 
     let button7 = UIButton(frame: CGRect(x: 370, y: 0, width: 60, height: 20)) 

     button7.setTitleColor(UIColor.blackColor(), forState: .Normal) 

     button7.setTitle("On Chips", forState: .Normal) 
     button7.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
     button7.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
     myStackview.addSubview(button7) 
    } 

Hier meine Schaltflächen hinzufügen, aber an einer bestimmten Position in Stackview. Meine Anforderung ist, dass zum Beispiel, wenn Button1-Bedingung nicht erfüllt ist, dann sollte 2. Button an der Stelle der ersten so kommen ??

die Tasten sollten wie Radiobuttons verhalten

Sie diesen Code verwenden können:

var posX = 0 
var posY = 0 
if trim.contains("0"){ 
print("contaim 0") 
let button1 = UIButton(frame: CGRect(x: posX, y: posY, width: 60, height: 20)) 
button1.setTitleColor(UIColor.blackColor(), forState: .Normal) 
button1.setTitle("No", forState: .Normal) 
button1.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
button1.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
myStackview.addSubview(button1) 
posX = 60 
} 
if trim.contains("1") { 
print("contaim 1") 

let button2 = UIButton(frame: CGRect(x: posX, y: posY, width: 60, height: 20)) 
button2.setTitleColor(UIColor.blackColor(), forState: .Normal) 
button2.setTitle("Less", forState: .Normal) 
button2.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
button2.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
myStackview.addSubview(button2) 
posX = posX + 60 
} 
if trim.contains("2"){ 
print("contaim 2") 

let button3 = UIButton(frame: CGRect(x: posX, y: posY, width: 60, height: 20)) 
button3.setTitleColor(UIColor.blackColor(), forState: .Normal) 

button3.setTitle("Half", forState: .Normal) 
button3.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
button3.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
myStackview.addSubview(button3) 
posX = posX + 60 
} 
if trim.contains("3"){ 
print("contaim 3") 
let button4 = UIButton(frame: CGRect(x: posX, y: posY, width: 60, height: 20)) 

button4.setTitleColor(UIColor.blackColor(), forState: .Normal) 

button4.setTitle("On", forState: .Normal) 
button4.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
button4.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
myStackview.addSubview(button4) 
posX = posX + 60 
} 
if trim.contains("4"){ 
print("contaim 4") 
let button5 = UIButton(frame: CGRect(x: posX, y: posY, width: 60, height: 20)) 

button5.setTitleColor(UIColor.blackColor(), forState: .Normal) 

button5.setTitle("With", forState: .Normal) 
button5.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
button5.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
myStackview.addSubview(button5) 
posX = posX + 60 
} 
if trim.contains("5"){ 
print("contaim 5") 
let button6 = UIButton(frame: CGRect(x: posX, y: posY, width: 60, height: 20)) 

button6.setTitleColor(UIColor.blackColor(), forState: .Normal) 

button6.setTitle("On Burger", forState: .Normal) 
button6.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
button6.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
myStackview.addSubview(button6) 
posX = posX + 60 
} 
if trim.contains("6"){ 
print("contaim 6") 
let button7 = UIButton(frame: CGRect(x: posX, y: posY, width: 60, height: 20)) 

button7.setTitleColor(UIColor.blackColor(), forState: .Normal) 

button7.setTitle("On Chips", forState: .Normal) 
button7.setImage(UIImage(named: "checkbox untick.png")!, forState: .Normal) 
button7.addTarget(self, action: #selector(buttonAction), forControlEvents: .TouchUpInside) 
myStackview.addSubview(button7) 
}
