Swift：JSON属性转换 - 将JSON数据类型改变为相同的Swift数据类型_course

<div class="post-text" itemprop="text"> <p>I've come across an interesting issue when trying to use a JSON feed generated by PHP/MySQL using PDO. By default, the result of a query e.g. <code>SELECT COUNT(id) FROM table name</code> is returned as a <code>String</code>, but when I do any mathematical calculations on the result e.g. <code>$result = $result + 1;</code> the result is the 'correct' datatype.</p> <p>In PHP, that's been no problem, but I'm using JSON to send these results to my iOS app, so although I know what datatype I want something to be in iOS, I don't know what type it's going to be when it reaches me. For example, I'd like to do:</p> <pre><code>if let json = jsonResult as? [String:Any] { let score = jsonData["score"] as? Int ?? 0 let years = jsonData["years"] as? String } </code></pre> <p>But:</p> <ol> <li>If <code>score</code> is a <code>String</code> in the JSON (e.g. <code>score:"7"</code>), <code>score</code> will just end up as <code>0</code></li> <li>If <code>years</code> is an <code>Integer</code> in the JSON (e.g. <code>years:2015</code>), years will end up as <code>nil</code></li> </ol> <p>I realise that making the JSON correct is the best way to achieve this, however is there a reliable way to do this in iOS? For the sake of this question, assume that I cannot change the JSON.</p> <p>I'm ideally looking for a sensible one-liner, that will allow me to convert to the correct datatype, regardless of what type it was previously (i.e. in the above example <code>years</code> will become a <code>String</code>, regardless of whether it was a <code>String</code> or <code>Int</code> in the JSON, and score will become an <code>Int</code> regardless of whether it was a <code>String</code> or an <code>Int</code> in the JSON)?</p> <p>Many thanks in advance!</p> </div>

如何使用Facebook身份验证进行休息api_course

<div class="post-text" itemprop="text"> <p>I want to make an iOS app that need to communicate with a webservice/restful api to get data from a Mysql DB.

So my question is how do I authorize the logged in facebook user? </p> <p>I was thinking when a Facebook user login via my iOS app I save the required Facebook users data in a table called "users" with a post request from the iOS app. And let say a user has many images. So if I want to get all images for a certain user from my iOS app I will send the access-token to my webservice and from my webservice I'll find users id by using the access_token (making a post request to facebook api to get user details) and with the users id I can get the images that belongs to. </p> <p>As said I'm new to all these technologies so if I'm wrong please correct me and help me further - Thank you</p> <p>PS: I have read something called Social Authentication in laravel, but haven't digged deeper into it.</p> </div>
