我正在开发一款试图获取用户位置并在查询中查看内容的应用。我已经在框架中添加了corelocation并将其导入到viewcontroller中，但是我收到一条错误说＆＃34; currLocation＆＃34;是一个未解决的标识符和＆＃34;位置管理器＆＃34;在queryfortable函数和位置管理器函数下是不明确的。我该如何解决这个错误？
import UIKit
import CoreLocation
import Parse
@available(iOS 8.0, *)
class TableViewController: UITableViewController,CLLocationManagerDelegate {
let bubbleFeeds = [
("1"),
("2"),
("I3"),
("4"),
("5"),
("6") ]
let locationManager = CLLocationManager()
var currLocation : CLLocationCoordinate2D?
private func alert(message : String) {
let alert = UIAlertController(title: "Oops something went wrong.", message: message, preferredStyle: UIAlertControllerStyle.Alert)
let action = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)
let cancel = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil)
let settings = UIAlertAction(title: "Settings", style: UIAlertActionStyle.Default) { (action) -> Void in
UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString)!)
return
}
alert.addAction(settings)
alert.addAction(action)
self.presentViewController(alert, animated: true, completion: nil)
}
var resultsNameArray = [String]()
var resultsImageFiles = [PFFile]()
var resultsBubbleArray = [String]()
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return resultsNameArray.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("BubbleCell", forIndexPath: indexPath) as! Bubbles
let BubbleCell = PFObject(className: "BubbleTest")
cell.name.text = PFUser.valueForKey("userName") as! String
cell.message.text = PFObject.valueForKey("textField") as! String
cell.dateTime.text = "\((indexPath.row + 1) * 3)m ago"
cell.message.numberOfLines = 0
let score = PFObject.valueForKey("count") as! Int
cell.LikeCounter.text = "\(score)"
let replycnt = PFObject.valueForKey("replies") as! Int
cell.responseCounter.text = "\(replycnt) replies"
cell.img.image = PFUser.currentUser()?.valueForKey("photo") as! PFFile
return cell
}
override func viewDidLoad() {
super.viewDidLoad()
locationManager.desiredAccuracy = 1000
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
_ = currLocation
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
("Cannot fetch your location")
}
}
在代码的这些部分中，我遇到了＆＃34; currLocation＆＃34;和＃34; locationManager＆＃34;暧昧。
func queryForTable() -> PFQuery! {
let query = PFQuery(className: "BubbleTest")
if let queryLoc = currLocation {
query.whereKey("location", nearGeoPoint: PFGeoPoint(latitude: queryLoc.latitude, longitude: queryLoc.longitude), withinMiles: 10)
query.limit = 200;
query.orderByDescending("createdAt")
} else {
/* Decide on how the application should react if there is no location available */
query.whereKey("location", nearGeoPoint: PFGeoPoint(latitude: 37.411822, longitude: -121.941125), withinMiles: 10)
query.limit = 200;
query.orderByDescending("createdAt")
}
return query
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
locationManager.stopUpdatingLocation()
if(locations.count > 0){
let location = locations[0]
print(location.coordinate)
currLocation = location.coordinate
} else {
alert("Cannot receive your location")
}
}
过去两天我一直试图解决这个问题，这让我疯狂。如果有人可以请求帮助，我会非常感激。
