I have this code in Swift using Xcode 7.2 ..
我使用Xcode 7.2在Swift中有这个代码..
func silentPostData(serverName: String, serverport serverPort: String, serverurl serverURL: String, parameters: [NSObject : AnyObject], urldata urlData: NSData) {
let persist = Persistence()
var finalURl = "https://\(serverName):\(serverPort)/\(serverURL)"
for key : String in parameters {
finalURL = finalURL.stringByAppendingString(key)
finalURL = finalURL.stringByAppendingString("=")
finalURL = finalURL.stringByAppendingString((parameters[key] as! String))
finalURL = finalURL.stringByAppendingString("&")
}
}
I get an error(mentioned as the title) in the line "for key : String in parameters {" . Based on the previous answer '(NSObject, AnyObject)' is not convertible to 'String' , i tried casting it to NSString , but it didn't work.So Anyone knows how to convert [NSObject:AnyObject] to string ? Thank You in advance.
我在“for key:String in parameters {”行中得到一个错误(在标题中提到)。基于前面的答案'(NSObject,AnyObject)'不能转换为'String',我试着将它转换为NSString,但它没有工作。所以任何人都知道如何将[NSObject:AnyObject]转换为字符串?先谢谢你。

Like the comments said, it's a dictionary and you could get the strings by doing this:
就像评论说的那样,它是一本字典,你可以通过这样做得到字符串:
parameters.keys.flatMap { $0 as? String }.forEach {
finalURL = finalURL.stringByAppendingString($0)
finalURL = finalURL.stringByAppendingString("=")
finalURL = finalURL.stringByAppendingString(parameters[$0] as? String ?? "")
finalURL = finalURL.stringByAppendingString("&")
}
