标签: arrays swift escaping closures

我想获得最终结果joblist数组以使用外部闭包。因为我想使用Joblist数组设置tableview。

let geoCoder = CLGeocoder()
geoCoder.geocodeAddressString(address) { (placemarks, error) in
    if error == nil && (placemarks?.count)! > 0 {

        let location2 = placemarks?[0].location

        if let location1 = self.locationManager?.location {
            let distanceInMeters = location1.distance(from: location2!)
            let IntDis = Int(distanceInMeters)
            //print(IntDis)

            if IntDis < 40000 {

                //print(address)

                if let activityid       = infoDictionary["ActivityID"] {self.newJob.ActivityID=activityid}
                if let companyname      = infoDictionary["CompanyName"] {self.newJob.CompanyName=companyname}
                if let quantity         = infoDictionary["Quantity"] {self.newJob.Quantity=quantity}
                if let coupontitle      = infoDictionary["Title"] {self.newJob.CouponTitle=coupontitle}
                if let couponterms      = infoDictionary["Terms"] {self.newJob.CouponTerms=couponterms}
                if let expirdate        = infoDictionary["ExpirDate"] {self.newJob.ExpirDate=expirdate}
                if let contactperson    = infoDictionary["ContactPerson"] {self.newJob.ContactPerson=contactperson}
                if let tel              = infoDictionary["TEL"] {self.newJob.TEL=tel}

                self.joblist.append(self.newJob)
                //print(self.joblist)
                //self.tableView.reloadData()

            }
        }
    }
}

答案 0 :(得分:0)

您可以通过两种方式执行此操作:

  1. // prints out the array in uppercase System.out.println(Arrays.toString(names10).toUpperCase()); 变量设为全局,以便可以从多个位置访问
  2. 使用回调,该回调在传递先前收集的数据时调用新函数。当原始“数据获取”过程是具有延迟的网络任务时,这尤其有用。
  3. 全局变量:

    joblist

    使用回调(简单版本不会将自身传递给下一个函数):

    let geoCoder = CLGeocoder()
    var jobList = [AnyClass]() //make a global array
    geoCoder.geocodeAddressString(address) { (placemarks, error) in
       ...filtering code ...
       joblist.append(self.newJob)
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
       let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
       cell.textLabel = jobList[indexPath.row].ActivityID //or something else with the data 
    }
