IG 似乎发生了很多变化。许多 OAuth2 存储库，似乎都有错误，或者真的不容易转换为 Swift3。想知道是否有人有迁移到 Swift3 并处理 Instagram 最新变化的解决方案？
欢迎提供解决方案。 OAuth2 的实现似乎是最复杂的事情之一。令 IG 没有提供他们自己的关于如何使用 iOS 执行此操作的示例文档感到惊讶。他们只有基于 Web 的解决方案的文档。
也许那里正在酝酿什么？他们有数以亿计的编码员。但就目前而言，正在寻找一个（我敢说？）简单的解决方案。
感谢一百万。 :-)

标签： ios swift swift3 instagram oauth2
对于 Swift 3：
更新：2017 年 4 月 17 日：由于依赖关系损坏，Pods 的安装不再有效。因此，我已经翻录了所需的内容并使用桥接头创建了一个 new Github project 并将所有需要的文件存储在项目中。如果您克隆或下载 github 项目，您将立即能够登录 Instagram。
要在您的项目中使用这些文件，只需将所有文件从 SimpleAuth 文件夹拖放到您的项目中，确保标记copy item if needed
您还需要在 Instagram 开发者控制台中禁用 Disable implicit oAuth。
然后，您可以将我的代码从桥接头复制/粘贴到您的或使用我的。在目标的构建设置中设置桥接头。
其他一切都和以前一样：
我有一个 Instagram 帐户的结构：
struct InstagramUser {
var token: String = ""
var uid: String = ""
var bio: String = ""
var followed_by: String = ""
var follows: String = ""
var media: String = ""
var username: String = ""
var image: String = ""
}
接收令牌的函数：
typealias JSONDictionary = [String:Any]
var user: InstagramUser?
let INSTAGRAM_CLIENT_ID = "16ee14XXXXXXXXXXXXXXXXXXXXXXXXX"
let INSTAGRAM_REDIRECT_URI = "http://www.davidseek.com/just_a_made_up_dummy_url" //just important, that it matches your developer account uri at Instagram
extension ViewController {
func connectInstagram() {
let auth: NSMutableDictionary = ["client_id": INSTAGRAM_CLIENT_ID,
SimpleAuthRedirectURIKey: INSTAGRAM_REDIRECT_URI]
SimpleAuth.configuration()["instagram"] = auth
SimpleAuth.authorize("instagram", options: [:]) { (result: Any?, error: Error?) -> Void in
if let result = result as? JSONDictionary {
var token = ""
var uid = ""
var bio = ""
var followed_by = ""
var follows = ""
var media = ""
var username = ""
var image = ""
token = (result["credentials"] as! JSONDictionary)["token"] as! String
uid = result["uid"] as! String
if let extra = result["extra"] as? JSONDictionary,
let rawInfo = extra ["raw_info"] as? JSONDictionary,
let data = rawInfo["data"] as? JSONDictionary {
bio = data["bio"] as! String
if let counts = data["counts"] as? JSONDictionary {
followed_by = String(describing: counts["followed_by"]!)
follows = String(describing: counts["follows"]!)
media = String(describing: counts["media"]!)
}
}
if let userInfo = result["user_info"] as? JSONDictionary {
username = userInfo["username"] as! String
image = userInfo["image"] as! String
}
self.user = InstagramUser(token: token, uid: uid, bio: bio, followed_by: followed_by, follows: follows, media: media, username: username, image: image)
} else {
// this handles if user aborts or the API has a problem like server issue
let alert = UIAlertController(title: "Error!", message: nil, preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
if error != nil {
print("Error during SimpleAuth.authorize: \(error)")
}
}
}
}
Instagram 还说：
重要
即使我们的访问令牌没有指定过期时间，您的 应用程序应处理用户撤销访问权限或 Instagram 会在一段时间后过期令牌。如果令牌是 不再有效，API 响应将包含 “error_type=OAuthAccessTokenException”。在这种情况下，您需要 重新认证用户以获得新的有效令牌。换一种说法： 不要假设您的 access_token 永远有效。
所以处理收到OAuthAccessTokenException的情况
