提问by Jason G
shows that there were a couple of changes
显示有一些变化
func geocodeAddressString(_ addressString: String!, completionHandler completionHandler: CLGeocodeCompletionHandler!)
to:
到：
func geocodeAddressString(_ addressString: String, completionHandler completionHandler: CLGeocodeCompletionHandler)
my code was:
我的代码是：
var geocoder = CLGeocoder()
geocoder.geocodeAddressString("\(event!.street), \(event!.city), \(event!.country)", completionHandler: {(placemarks: [AnyObject]!, error: NSError!) -> Void in
if let placemark = placemarks?[0] as? CLPlacemark {
self.event!.lat = placemark.location!.coordinate.latitude
self.event!.long = placemark.location!.coordinate.longitude
self.event!.getMiles(self.currentLocation!.location!.coordinate.latitude, clong: self.currentLocation!.location!.coordinate.longitude)
var mile = self.event!.miles != nil ? NSString(format: "%.1f miles", self.event!.miles!) : "Location services off"
self.milesButton.setTitle(mile as String, forState: .Normal)
}
})
tried:
试过：
var geocoder = CLGeocoder()
let address = "\(event!.street), \(event!.city), \(event!.country)"
geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]) in
let placemark = placemarks[0]
self.event!.lat = placemark.location!.coordinate.latitude
self.event!.long = placemark.location!.coordinate.longitude
self.event!.getMiles(self.currentLocation!.location!.coordinate.latitude, clong: self.currentLocation!.location!.coordinate.longitude)
var mile = self.event!.miles != nil ? NSString(format: "%.1f miles", self.event!.miles!) : "Location services off"
self.milesButton.setTitle(mile as String, forState: .Normal)
})
it just keeps saying that its not allowed. tried a few different combinations. this is do to the latest update to xcode / swift
它只是一直说这是不允许的。尝试了几种不同的组合。这是对 xcode / swift 的最新更新所做的
thanks in advance

In Swift 2:
在 Swift 2 中：
geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]?, error: NSError?) -> Void in
})
In Swift 3, replace NSError?with Error?:
在 Swift 3 中，替换NSError?为Error?：
geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]?, error: Error?) -> Void in
})
Or, easier, just let it infer the correct types for you:
或者，更简单，让它为您推断正确的类型：
geocoder.geocodeAddressString(address) { placemarks, error in
}

Use geocodeAddressStringthis way:
使用geocodeAddressString这种方式：
geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]?, error: NSError?) -> Void in
})
And it will work fine.
它会正常工作。

geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]?, error: NSError?) -> Void in
})
Just change NSErrorto Errorand will it work
只需更改NSError为Error并且它会起作用

This no longer works....
这不再有效....
geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]?, error: NSError?) -> Void in
print("Test")
} as! CLGeocodeCompletionHandler)
throws an EXC error
抛出 EXC 错误
