也有類似的問題，但沒有回答我的問題。Swift：錯誤：鏈接器命令失敗，退出代碼爲1
我正在使用Swift 2.0我正在使用CoreLocation顯示經度和緯度的項目。
我也在使用Social框架發佈到twitter和facebook。
我得到一個錯誤，說「錯誤：鏈接器命令失敗，退出代碼1」，然後它告訴我「（使用-v看到調用）」，但我不明白這一點。
我在這裏寫下位置服務部分的答案。這裏是鏈接https://stackoverflow.com/a/24696878/6140339
這裏是我的代碼：
import UIKit
import Social
import CoreLocation
@UIApplicationMain
class FirstViewController: UIViewController, CLLocationManagerDelegate, UIApplicationDelegate {
var window: UIWindow?
var locationManager: CLLocationManager!
var seenError : Bool = false
var locationFixAchieved: Bool = false
var locationStatus : NSString = "Not Started"
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
initLocationManager();
return true
}
func initLocationManager() {
seenError = false
locationFixAchieved = false
locationManager = CLLocationManager()
locationManager.delegate = self
CLLocationManager.locationServicesEnabled()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
locationManager.stopUpdatingLocation()
if (error == true) {
if (seenError == false) {
seenError = true
print(error)
}
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if (locationFixAchieved == false) {
locationFixAchieved = true
let locationArray = locations as NSArray
let locationObj = locationArray.lastObject as! CLLocation
let coord = locationObj.coordinate
print(coord.latitude)
print(coord.longitude)
}
}
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
var shouldIAllow = false
switch status {
case CLAuthorizationStatus.Restricted:
locationStatus = "Restricted Access to location"
case CLAuthorizationStatus.Denied:
locationStatus = "User denied access to location"
case CLAuthorizationStatus.NotDetermined:
locationStatus = "Status not determined"
default:
locationStatus = "Allowed to location Access"
shouldIAllow = true
}
NSNotificationCenter.defaultCenter().postNotificationName("LabelHasBeenUpdated", object: nil)
if (shouldIAllow == true) {
NSLog("Location to Allowed")
//Start location services
locationManager.startUpdatingLocation()
} else {
NSLog("Denied access: \(locationStatus)")
}
}
@IBAction func postToFacebookButton(sender: UIButton) {
if(SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook)){
let socialController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
//creates post with pre-desired text
socialController.setInitialText("")
self.presentViewController(socialController, animated: true, completion: nil)
}
}
@IBAction func postTweetButton(sender: UIButton) {
if(SLComposeViewController.isAvailableForServiceType(SLServiceTypeTwitter)){
let socialController = SLComposeViewController(forServiceType: SLServiceTypeTwitter)
//creates post with pre-desired text
socialController.setInitialText("")
self.presentViewController(socialController, animated: true, completion: nil)
}
}
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {

}

你可以看到連接器輸出，如果你選擇在Project Navigator的最後一個圖標（講話泡泡），然後展開你的「構建」日誌。查找紅色鏈接器錯誤，然後單擊以展開該文本;它應該顯示爲什麼鏈接程序無法完成 – Paulw11
