在Swift中使用tableview复选框
我是Swift编程新手
Tableview有两个复选框[out，Absent]检查/取消选中正常工作。
注1：在数组数据追加后检查复选框中的任何一个是否缺失并将数据传递给函数：
out =＆gt; checked ==＆gt;数组数据追加==＆gt;数据传递给函数
缺席=＆gt;已检查==＆gt; data append ==＆gt;数据传递给函数
个人运作良好。
注意2：如果我可以单击Out框，out box数据附加到数组并立即传递给函数我想更改Absent复选框然后清除Appended out Data并将Absent数据发送到函数
out ==＆gt; checked ===＆gt; data append ==＆gt; changetoAbsent ==＆gt; cleartheoutdata =＆gt;＆gt;追加缺席数据
如果我可以检查并取消选中
之类的输出/缺席功能数据正文数据状态= 2＆amp; staffId = 18＆amp; studentId = 5＆amp; attendanceId = 6677
正文数据状态= 3＆amp; staffId = 18＆amp; studentId = 5＆amp; attendanceId = 6677
正文数据状态= 2＆amp; staffId = 18＆amp; studentId = 5＆amp; attendanceId = 6677
我选中该复选框数据只传递给函数
这是代码：
var InCheckec = [Bool]()
var OutCheckec = [Bool]()
var AbsentCheckec = [Bool]()
var upStudentId = [String]()
var upAttendanceID = [String]()
var upStatus : String = ""
var upStaffId : String = ""

var inButtoncount : Int = 0

快餐栏执行发送动作数据传递给功能
lazy var snackbar = TTGSnackbar(message: "Attendance Update !", duration: .long, actionText: "SEND") { (snackbar) in
self.activityIndicatorView.startAnimating()
self.updateArray(_upstatus:UPstatusTest,UPStudentId:upStudentId,UPAttendanceID:upAttendanceID,UPStaffId:upStaffId,inBcount:inButtoncount)
UPstatusTest.removeAll()
upStudentId.removeAll()
upAttendanceID.removeAll()
inButtoncount = 0
}
将数据传递给函数后
func updateArray(_upstatus:[String],UPStudentId:[String],UPAttendanceID:[String],UPStaffId:String,inBcount:Int)
{
for i in 0..<inBcount
{
var errorCode = "1"
_ = "Failed"
var request = URLRequest(url: URL(string: "updateattendance",
relativeTo: URL(string: serverURL+"/rkapi/api/"))!)
let session = URLSession.shared
request.httpMethod = "POST"
let bodyData = "status=\(_upstatus[i])&staffId=\(UPStaffId)&studentId=\(UPStudentId[i])&attendanceId=\(upAttendanceID[i])"
print("body data \(bodyData)")
request.httpBody = bodyData.data(using: String.Encoding.utf8);
let task = session.dataTask(with: request, completionHandler: { (data, response, error) in

if(errorCode == "0")
