问题 I am using Xcode 8 and Swift 2.3 I went through couple of websites, which are guides about state restoration methods: https://www.raywenderlich.com/117471/state-restoration-tutorial https://github.com/shagedorn/StateRestorationDemo/blob/master/StateRestorationDemo/CityViewController.swift But I need to store and restore the state of the view controller on button click with passing identified key. I cant use single identifier in storyboard because I need to save many instances of the same

问题 I am trying to decode JSON object using Codable with Swift 4: { USD: { "15m": 9977.49, last: 9977.49, buy: 9979.36, sell: 9975.62, symbol: "$" }, AUD: { "15m": 13181.69, last: 13181.69, buy: 13184.16, sell: 13179.22, symbol: "$" }, TBD: { "15m": 13181.69, last: 13181.69, buy: 13184.16, sell: 13179.22, symbol: "$" } } This is what I've done so far with a model of an object: struct Currency: Codable { let fifteenMin: Double? let last: Double? let buy: Double let sell: Double let symbol: String

问题 How can I convert/decode a text in غلامحسين format to normal text? I'm using SQL server 2012. I just want to update all of them to normal text. 回答1: If you know Firstname and Lastname are valid when interpreted as XML, then this will do: UPDATE _table_ SET Firstname = CONVERT(NVARCHAR(MAX), CONVERT(XML, FirstName)), Lastname = CONVERT(NVARCHAR(MAX), CONVERT(XML, LastName)) The XML parser will decode the entities for you. 回答2: For some reason Jeroen's answer doesn't seem to work for me in SQL

问题 I have a string like this: La Torre Eiffel paragonata all’Everest What PHP function should I use to convert the ’ to the actual "normal" char ' : La Torre Eiffel paragonata all’Everest I'm using CURL to fetch a page and this page has that string in it but for some reason the HTML chars are not decoded. The my_url test page is an Italian blog with iso characters, and all the apostrophes are encoded in html code like above. $output = curl_download($my_url); $output = htmlspecialchars_decode(

问题 Im stuck on an issue on my objective C App. I'm reading a byte array from a serveur (Socket c#) who send me an PCM encoded sound, and i'm currently looking for a sample code that decode for me this byte array (NSData), and play it. Does anyone know a solution ? Or how can I read a u-Law audio? Thanks a lot ! :D 回答1: This link has information about mu-law encoding and decoding: http://dystopiancode.blogspot.com.es/2012/02/pcm-law-and-u-law-companding-algorithms.html #define MULAW_BIAS 33 /* *

问题 So I have a fairly large system which we have encoded with Zend Guard. As this pretty badly messes up any SVN control, its a bit of a pain to deploy / make changes. Does anyone know if its possible to use the Zend Studio FTP editing to decode and edit files that have been encoded? When I open them it says The file filepath/filename.php was encoded by Zend Guard. Would you like to open it anyway? If you click yes, it just opens the raw encoded file. I have both Zend Guard / Studio installed on

问题 How do you decode json to a generic model in swift? In java for decoding json I use GSON and in general it does not matter I use <T<E>> or ArrayList<E> .In swift Array is a struct and can't be inheritance and it has not implemented Decodable. I'm looking for a generic elegant class to use in all my web service. My scenario: I have json response { "status": true, "message": "", "code": 200, "response": [{ "id": 43 }] } and a generic reponse model like this from web services: class

问题 I have the following JSON response from a webservice method which will return byte[] in PDF format: JVBERi0xLjQKJeLjz9MKMSAwI......nVq2P63zkirBH1z9aW3pDxn6F7q9TFV== The return value is a byte() array. I been trying for a few days trying to use the function available in one of the questions posted in "Generating PDF from Base64 string in VBA" to generate PDF from the above Base64 Byte array, but I couldn't. What I have done is that based on the return byte array from the webservice method, I

问题 I'm sure I'm overlooking something simple here, but anyway - I'm trying to build a PL/SQL procedure which implements AVG via a decode function, see below. I keep getting an arithmetic overflow error but can't figure out what needs changing to hold the right size for the type (or even if that's what's required!) If I change the AVG to Count, Sum or Max, all is fine, so I know the decode is working correctly, I'm just not sure why AVG isn't. Any pointers greatly appreciated. Rgds BBz PROCEDURE
