如何在 swift 3 在 ios 9 中使用 Alamofire？

Question

我制作了 swift 应用程序，我将使用 Alamofire 进行 swift json 解析。

为此，我安装了以下 pod：

pod 'Alamofire', '~> 4.4'

之后我更新了 pod，但它会给我以下错误：

[!] CocoaPods 无法更新 master 存储库。如果这是一个意外问题并且仍然存在，您可以检查它运行 pod repo update --verbose

所以谁有解决方案，请帮助我。

我使用 xcode 8.3.1，Swift 3 和 ios 9.0.

的应用程序兼容性

Answer 1

This answer 可以解决您的问题：

卸载CocoaPods（选择卸载所有版本）：

sudo gem uninstall cocoapods

删除旧的主仓库：

sudo rm -fr ~/.cocoapods/repos/master

不使用 sudo 安装 CocoaPods：

gem install --user-install cocoapods

设置 CocoaPods 和主存储库：

pod setup

注意：第 3 步将确保您将 pod 安装在您的用户名下，而不是 sudo 执行的 root 下。

对于iOS Swift 4 :

第 1 步 - 安装 pod

pod 'Alamofire'

第 2 步 - 导入 Alamofire（在您的 VC 中）

第 3 步 - 创建 URL 和参数

let params:[String:String] = ["Name":self.name]
or
let params = nil

第 4 步 - 调用函数

public func GET_ALL(params:[String:String])
    
{
    let baseURL = "your url"
    
    if NetworkReachabilityManager()?.isReachable == true
    {
        AppDelegate.sharedInstance().ShowSpinnerView()
        Alamofire.request(baseURL, method: .post, parameters: params, encoding: JSONEncoding.default, headers: nil).response { (response) in
            AppDelegate.sharedInstance().HideSpinnerView()
            do
            {
                let dict = try? JSONSerialization.jsonObject(with: response.data!, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSMutableDictionary
                if dict?.count==0 || dict == nil
                {
                    let alert = UIAlertController(title: APPNAME, message: "No reposnse from server.", preferredStyle: .alert)
                    let action = UIAlertAction(title: "OK", style: .default, handler: { (action) in
                        
                    })
                    
                    alert.addAction(action)
                    self.present(alert, animated: true, completion: nil)
                }
                else
                {
                    self.checkDictionary(dict!)
                    if dict?.object(forKey: "data") is NSMutableDictionary
                    {
                        
                        self.arrAllData = (dict?.value(forKeyPath: "data.myName") as? NSMutableArray)!
                        
                        if(self.arrAllData.count == 0)
                        {
                          
                        }
                        else
                        {
                           
                        }
                        self.TableView.reloadData()
                    }
                    else
                    {
                        
                    }
                }
            }
            catch let error as NSError
            {
                print(error.localizedDescription)
                let alert = UIAlertController(title: APPNAME, message: error.localizedDescription, preferredStyle: .alert)
                let action = UIAlertAction(title: "OK", style: .default)
                { (action) in
                }
                
                alert.addAction(action)
                self.present(alert, animated: true, completion: nil)
                self.hideSpinner()
            }
        }
    }
    else
    {
        AppDelegate.sharedInstance().HideSpinnerView()
        let alert = UIAlertController(title: APPNAME, message: "No network available.", preferredStyle: .alert)
        let action = UIAlertAction(title: "OK", style: .default)
        { (action) in
        }
        alert.addAction(action)
        self.present(alert, animated: true, completion: nil)
    }
}

let params:[String:String] = ["slug":self.strSlug]

let header = ["Content-Type":"application/x-www-form-urlencoded", "Authorization": "Basic aW50cmFpZXAwMDE6dWZaeWFyUlp3NE1CeUg4RA==" ]

let url = API.GET_NEWS

Swift Alamofire Method Calling:

    let url = API.SERVER_URL + "\(page)"
    Alamofire.request(URL(string: url)!, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: nil).responseJSON { (responseObject) in

        let arr = response["results"] as! [[String : AnyObject]]

        self.tableView.reloadData()
        self.isLoadingList = false
        self.deleteAllRecords()
    }
}

func formatResponse(data:DataResponse<Any>)-> [String:AnyObject]
{
    let responseObject = data.result.value as? [NSObject: AnyObject]
    let response = responseObject as? [String : AnyObject]
    return response ?? [:]
