我想将位置地址的 googleMap Api 结果翻译成波斯语。我正在使用 YandexApi 翻译地址。用“،”分隔地址组件，并将此数组传递给 for api。我的问题是每次服务调用后我的用户界面都更新了。如何解决这个问题。例如，当我将此数组传递给方法时：["road","avenue"] 地址标签文本在每次翻译响应后更新 label = "جاده" 的第一个文本 label = "جاده ، خیابان" 的最后一个文本有我的代码：
func translateText(text:[String],closure:@escaping ((_ success:String?,_ error:Error?) -> Void)) {
var translateString: String = ""
var responseError: Error?
for item in text {
myGroup.enter()
let urlString = "https://translate.yandex.net/api/v1.5/tr.json/translate?key=trnsl.1.1.20171105T134956Z.795c7a0141d3061b.dc25bae76fa5740b2cdecb02396644dea58edd24&text=\(item)&lang=fa&format=plain&options=1"
if let allowString = Utilities.shareInstance.getQueryAllowedString(url: urlString) {
if let url = URL(string:allowString){
Alamofire.request(url).responseJSON { response in
guard let responseData = response.data else {
return
}
do {
let json = try JSONSerialization.jsonObject(with: responseData, options: [])
if let res = json as? [String:Any] {
if let code = res["code"] as? Int {
if code == 200 {
if let textArr = res["text"] as? [AnyObject] {
let flattArr = Utilities.shareInstance.flatStringMapArray(textArr)
if flattArr.count > 0 {
translateString += " ، " + flattArr[0]
}
}
}
}
}
}catch {
responseError = error
}
self.myGroup.leave()
closure(translateString, responseError)
}
}
}
}
}
private func translatingAddressArrayForChecking(address:[String]) {
var addressString = ""
let addressComponent = address
if addressComponent.count > 0 {
YandexTranslateAPI.shateInstance.translateText(text: addressComponent, closure:{ success,_ in
if let res = success {
addressString = res
OperationQueue.main.addOperation {
self.layoutActivity(start: false)
if self.searchState == .Origin && self.destinationButton.isHidden == false{
if let selectOrigin = self.originSelectedCity {
if let city = selectOrigin.city_title {
if addressString.contains(city) {
self.originAddressLabel.text = addressString
if let location = self.startCoordinate {
self.setOrigin(location: location)
}
}else {
self.CreateCustomTopField(text: "wrong city", color: Constants.ERROR_COLOR)
}
}
}
}else if self.searchState == .Destination || self.destinationButton.isHidden == true {
if let selectOrigin = self.destinationSelectedCity {
if let city = selectOrigin.city_title {
if addressString.contains(city) {
self.destinationAddressLabel.text = addressString
if let location = self.endCoordinate {
self.setDestination(location: location)
}
}else {
self.CreateCustomTopField(text: "wrong city", color: Constants.ERROR_COLOR)
}
}
}
}
}
}
})
}
地址标签文本使用数组组件更新多个。
