weak只能应用于类和类绑定协议类型而不是<< errortype >>

Question

我正在尝试添加地图,GMSMapView但是当我为视图创建插座时,我遇到了错误.

以下是代码段:

import UIKit
import GoogleMaps

class MapViewController: UIViewController {

    @IBOutlet weak var mapVIew: GMSMapView!
    @IBOutlet weak var mapCenterPinImage: UIImageView!
    @IBOutlet weak var pinImageVerticalConstraint: NSLayoutConstraint!
    var searchedTypes = ["bakery", "bar", "cafe", "grocery_or_supermarket", "restaurant"]
    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()
    }
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "Types Segue" {
            let navigationController = segue.destinationViewController as! UINavigationController
            let controller = navigationController.topViewController as! TypesTableViewController
            controller.selectedTypes = searchedTypes
            controller.delegate = self
        }
    }
}

我遇到了以下错误

@IBOutlet weak var mapVIew: GMSMapView!:

1. weak只能应用于类和类绑定协议类型而不是<>
2. 使用未声明类型"GMSMapView"

请有人帮助我

Answer 1

明确的答案不是这个问题的正确答案.如果其他人遇到此问题,问题是所需的框架未导入.在这种情况下,GoogleMaps.对此的修复是在文件添加的顶部

import GoogleMaps

另一个例子是如果在添加MkMapView后出现错误.

@IBOutlet weak var mapView: MKMapView

为此,您必须导入MapKit

import MapKit

Answer 2

注意：更新此答案以避免误解，因为我之前回答错误。感谢@Inn0vative1指出错误

为此你必须导入 MapKit

import MapKit

您的viewController未确认协议，请遵守CLLocationManagerDelegate协议

class MapViewController: UIViewController,CLLocationManagerDelegate {
}
