swift - 如何获取我的位置数据并将它们放入 iMessage 的变量中?
swift - How to get my location data and put them in variables for iMessage?
昨天我在stack Overflow这里问了一个关于如何在消息正文中嵌入我当前位置的问题
我得到了答案并更正了我的代码
我的代码在控制台中工作得很好,但我不知道如何从 displayLocationInfo 函数获取数据并将它们存储在变量中;然后将变量放入消息正文中。
我是 iPhone 开发领域的新手
有什么帮助吗?
class Location: NSObject,CLLocationManagerDelegate {
var locationManager = CLLocationManager()
var currentLocation : CLPlacemark?
var detectLocation : CLLocationManager?
var locManager = CLLocationManager()
func viewDidLoad()
{
viewDidLoad()
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.requestWhenInUseAuthorization()
self.locationManager.startUpdatingLocation()
}
func updateLocation()
{
locationManager.startUpdatingLocation()
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
locationManager.stopUpdatingLocation()
CLGeocoder().reverseGeocodeLocation(manager.location!, completionHandler: {(placemarks, error)->Void in
if (error != nil)
{
print("Error: " + error!.localizedDescription)
return
}
if placemarks!.count > 0
{
let pm = placemarks![0]
self.displayLocationInfo(pm)
}
else
{
print("Error with the data.")
}
})
}
func displayLocationInfo(placemark: CLPlacemark)
{
self.locationManager.stopUpdatingLocation()
print(placemark.locality)
print(placemark.postalCode)
print(placemark.administrativeArea)
print(placemark.country)
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError)
{
print("Error: " + error.localizedDescription)
}
}
import MessageUI
让您的 class 成为正确的委托人(这个委托人用于 iMessage):
MFMessageComposeViewControllerDelegate
创建一些全局变量来存储您要存储的字段(在当前代码中打印到控制台时设置它们):
class Location: NSObject,CLLocationManagerDelegate, MFMessageComposeViewControllerDelegate {
var locationManager = CLLocationManager()
var currentLocation : CLPlacemark?
var detectLocation : CLLocationManager?
var locManager = CLLocationManager()
//put your variables for your message below:
//you should use optionals (?) here but to keep it simple I'm assigning ""
var locality = ""
var postalCode = ""
//set your variables when you are currently printing them in the console:
func displayLocationInfo(placemark: CLPlacemark)
{
self.locationManager.stopUpdatingLocation()
print(placemark.locality)
print(placemark.postalCode)
print(placemark.administrativeArea)
print(placemark.country)
//here I set postalcode to be used in the message later
postalCode = placemark.postalCode
}
//call this function when the user hits a send button
func messageAction() {
if MFMessageComposeViewController.canSendText() {
let messageVC = MFMessageComposeViewController()
messageVC.messageComposeDelegate = self
messageVC.body = "\(postalCode) is my postalCode"
self.presentViewController(messageVC, animated: true, completion: nil)
}
else {
print("User hasn't setup Messages.app")
}
}
//if you have any code you want to run when the message is done sending put it in
func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {
self.dismissViewControllerAnimated(true, completion: nil)
switch (result.rawValue) {
case MessageComposeResultSent.rawValue:
print("Message sent success")
default:
return
}
}
另一种选择是使 messageAction() 方法具有包含在消息中的参数。比如 messageAction(postalCode: String?, locality: String?, municipality: String?) 等。这真的取决于你是否想在全局的其他方法中使用这些值。
回复发帖人的问题:
设置一个全局变量(查看上面这一行的大型代码示例)。它使 postalCode 成为全局变量。
var postalCode = ""
在 displayLocationInfo() 中将此变量设置为具有位置值:
postalCode = placemark.postalCode
在 messageAction() 中设置消息正文以使用该变量:
let messageVC = MFMessageComposeViewController()
messageVC.body = "\(postalCode) is my postalCode"
这将在短信中显示“12345 是我的邮政编码”window。
