無法弄清楚如何將字符串編碼爲Google靜態地圖API的URL iOS

Question

我現在真的絕望了。我一直在編寫和調試7個小時，從搞清楚如何在Google靜態地圖中繪製一個圓，將代碼從PHP和Java轉換爲Swift，以查看解決方案是否可行。

幸運的是，我非常幸運，並且能夠正確地生成一個Google靜態地圖。但是，我現在的問題是如何正確地將它（String URL）編碼到URL中。我嘗試了幾乎所有我發現的東西。

下面是我的日誌在我的瀏覽器工作URL樣本：

WORKING GOOGLE STATIC MAP LINK

https://maps.googleapis.com/maps/api/staticmap?size=640x320&&path=color:0x2EB7FCDD%7Cweight:1%7Cfillcolor:0x2EB7FC80%7Cenc:umdxAip_bVFqARmA^iAl@aAt@w@`Ao@dAa@jASlAGlAFjARdA`@`An@t@v@l@`A^hARlAFpAGnASlA_@hAm@`Au@x@aAl@eA`@kARmAFmAGkASeAa@aAm@u@y@m@aA_@iASmA&key=AIzaSyDLDkhgnS5gUjlXl5Jqt8fxJq87Figz8co&zoom=15 

我都想盡CharacterSet的編碼字符串轉換成URL。

有些結果是：無論是在我的瀏覽器或我的圖像下載功能，這些工作

無。 Swift或Objective-C的答案是受歡迎的。

編輯：當然，我使用的URL用於下載生成的靜態地圖圖像，像這樣（我使用了一個名爲Kingfisher庫）

let mapURL = URL(string: staticMapUrl.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!) 
self.imageView_Map.kf.setImage(
    with: mapURL, 
    placeholder: nil, 
    options: [.transition(.fade(1))], 
    progressBlock: { (receivedSize, totalSize) in 
    }, completionHandler: { (_, _, _, _) in }) 

Answer 1

翠鳥文檔說：

let url = URL(string: "url_of_your_image") 
    imageView.kf.setImage(with: url) 

所以，你所需要做的就是

let url = URL(string: "https://maps.googleapis.com/maps/api/staticmap?size=640x320&&path=color:0x2EB7FCDD%7Cweight:1%7Cfillcolor:0x2EB7FC80%7Cenc:umdxAip_bVFqARmA%5EiAl@aAt@w@%60Ao@dAa@jASlAGlAFjARdA%60@%60An@t@v@l@%60A%5EhARlAFpAGnASlA_@hAm@%60Au@x@aAl@eA%60@kARmAFmAGkASeAa@aAm@u@y@m@aA_@iASmA&key=AIzaSyDLDkhgnS5gUjlXl5Jqt8fxJq87Figz8co&zoom=15") 
    imageView.kf.setImage(with: url) 

我沒有看到你需要編碼。
