here code table view class

func numberofsections(in tableview: uitableview) -> int     {          if ((addressselected == true || checkispaymentradioselect == true) && selected == false) {             return 3         }else {             return 2         }     }     func tableview(_ tableview: uitableview, titleforheaderinsection section: int) -> string?     {         if ((addressselected == true || checkispaymentradioselect == true) && selected == false) {             if (section == 0) {                 return "shipping address"             }             else if (section == 2) {                 return "shipping method"             }             else  {                 return ""             }         }         else {                 if (section == 0) {                 return "shipping address"                 }                 else{                     return ""                 }         }     }     func tableview(_ tableview: uitableview, numberofrowsinsection section: int) -> int{         if (section == 0)         {             return shippingarray.count         }         else         {             return 1         }     }     func tableview(_ tableview: uitableview, heightforrowat indexpath: indexpath) -> cgfloat{         if ((addressselected == true || checkispaymentradioselect == true) && selected == false){             if (indexpath.section == 0){                 return uitableviewautomaticdimension             }             else if (indexpath.section == 1){                 return 62             }             else {                 print(height)                 return cgfloat(height)             }          }         else{             if (indexpath.section == 0){                 return uitableviewautomaticdimension             }             else if (indexpath.section == 1){                 return 62             }             else {                 return 0             }          }     }     func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {     if (indexpath.section == 0)     {         let cell = tableview.dequeuereusablecell(withidentifier: "cell", for: indexpath) as! addresstableviewcell         tabledetails.ishidden = false         activityindicator.stopanimating()         let arr = shippingarray[indexpath.row]         cell.deletebutton.tag = indexpath.row         cell.namelabel.text = arr["name"] as? string         cell.addresslabel.text = arr["address"]as? string         let mobilenumber : =  arr["number"] anyobject         cell.mobilenumberlabel.text = "\(mobilenumber)"         cell.radiobutton.tag = indexpath.row         cell.editbutton.tag = indexpath.row         cell.deletebutton.tag = indexpath.row         cell.editbutton.ishidden = true         cell.deletebutton.ishidden = true         cell.radiobutton.addtarget(self, action: #selector(selectradiobutton(_:)), for: .touchupinside)         cell.deletebutton.addtarget(self, action: #selector(deleteaction(button:)), for: .touchupinside)         let checkindex = self.checkisradioselect.index(of: indexpath.row)         if(checkindex != nil){             cell.radiobutton.isselected = true             cell.editbutton.ishidden = false             cell.deletebutton.ishidden = false         }         else         {             cell.radiobutton.isselected = false             cell.editbutton.ishidden = true             cell.deletebutton.ishidden = true         }         if (checkispaymentradioselect == true){         let defaultvalue  = arr["default"] as! int         if defaultvalue == 1 {             cell.radiobutton.isselected = true             cell.editbutton.ishidden = false             cell.deletebutton.ishidden = false             addressselected = true             tabledetails.tablefooterview?.ishidden = false         }         }         return cell     }     else if (indexpath.section == 1){         let cell = tableview.dequeuereusablecell(withidentifier: "addresscell", for: indexpath) as! createnewaddresstableviewcell         cell.newaddressbutton.addtarget(self, action: #selector(newaddressaction(_:)), for: .touchupinside)         return cell     }     else {         let cell = tableview.dequeuereusablecell(withidentifier: "shippingmethodcell", for: indexpath) as! methodtableviewcell         cell.delegate = self         cell.booldelegate = self         cell.shippingtableview.reloaddata()         if shippingradio == true {             cell.select = shippingradio             cell.boolselected()             cell.shippingmethodurl()             cell.shippingtableview.reloaddata()         }         else{             cell.select = methodradio             cell.shippingtableview.reloaddata()         }         return cell     } }

in cell class had got api data , passed table view shown in code need call api during cell selection of address can me how clear error or alternative this

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
