Ios 想在iPhone应用程序中显示twitter好友列表吗
我正在使用iOS5的Twitter和帐户框架。Ios 想在iPhone应用程序中显示twitter好友列表吗,ios,objective-c,iphone,Ios,Objective C,Iphone,我正在使用iOS5的Twitter和帐户框架。 问题是，我无法使用“此api”获取好友列表。但从twitter api资源管理器中，我获取了好友列表。（twitter资源管理器api=）。我使用的是用于iOS的twitter原生框架 要从Twitter获取好友列表，您可以这样做（四个步骤） 将Twitter和帐户框架添加到项目中 获取当前Twitter帐户实例 然后您将通过API从Twitter获得好友ID列表 请求 最后，您可以通过ID和 排列 所以…你的.h文件应该是这样的 #import

对于Swift 4.2、Xcode 10.1和iOS 12.1中的（int i=0；i）
如果你想从twitter上获取好友/列表数据，你需要使用两个API
1）oauth2/tokenAPI
2）好友/列表API
在oauth2/tokenapi中，您可以获得访问令牌，因为您需要朋友列表的访问令牌。并且您需要用户id、屏幕名称
但在这里，你必须记住一个要点
1） 首先对访问令牌使用oauth2/tokenapi
2） 获取访问令牌后，使用推特登录用户id和屏幕名称的api。
3） 现在使用friends/listapi
首先，如果您使用twitter登录，然后使用oauth2/token api访问token，您可能会得到类似错误的身份验证数据
1）获取访问令牌代码（oauth2/tokenAPI）：
func getAccessToken() {
//RFC encoding of ConsumerKey and ConsumerSecretKey
let encodedConsumerKeyString:String = "sx5r...S9QRw".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
let encodedConsumerSecretKeyString:String = "KpaSpSt.....tZVGhY".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
print(encodedConsumerKeyString)
print(encodedConsumerSecretKeyString)
//Combine both encodedConsumerKeyString & encodedConsumerSecretKeyString with " : "
let combinedString = encodedConsumerKeyString+":"+encodedConsumerSecretKeyString
print(combinedString)
//Base64 encoding
let data = combinedString.data(using: .utf8)
let encodingString = "Basic "+(data?.base64EncodedString())!
print(encodingString)
//Create URL request
var request = URLRequest(url: URL(string: "https://api.twitter.com/oauth2/token")!)
request.httpMethod = "POST"
request.setValue(encodingString, forHTTPHeaderField: "Authorization")
request.setValue("application/x-www-form-urlencoded;charset=UTF-8", forHTTPHeaderField: "Content-Type")
let bodyData = "grant_type=client_credentials".data(using: .utf8)!
request.setValue("\(bodyData.count)", forHTTPHeaderField: "Content-Length")
request.httpBody = bodyData
let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(String(describing: error))")
return
}
let responseString = String(data: data, encoding: .utf8)
let dictionary = data
print("dictionary = \(dictionary)")
print("responseString = \(String(describing: responseString!))")
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
do {
let response = try JSONSerialization.jsonObject(with: data, options: []) as! Dictionary<String, Any>
print("Access Token response : \(response)")
print(response["access_token"]!)
self.accessToken = response["access_token"] as! String
self.getStatusesUserTimeline(accessToken:self.accessToken)
} catch let error as NSError {
print(error)
}
}
task.resume()
}
2）使用twitter代码登录
@IBAction func onClickTwitterSignin(_ sender: UIButton) {
//Login and get session
TWTRTwitter.sharedInstance().logIn { (session, error) in
if (session != nil) {
//Read data
let name = session?.userName ?? ""
print(name)
print(session?.userID ?? "")
print(session?.authToken ?? "")
print(session?.authTokenSecret ?? "")
// self.loadFollowers(userid: session?.userID ?? "")
//Get user email id
let client = TWTRAPIClient.withCurrentUser()
client.requestEmail { email, error in
if (email != nil) {
let recivedEmailID = email ?? ""
print(recivedEmailID)
} else {
print("error--: \(String(describing: error?.localizedDescription))");
}
}
//Get user profile image url's and screen name
let twitterClient = TWTRAPIClient(userID: session?.userID)
twitterClient.loadUser(withID: session?.userID ?? "") { (user, error) in
print(user?.profileImageURL ?? "")
print(user?.profileImageLargeURL ?? "")
print(user?.screenName ?? "")
}
let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
self.navigationController?.pushViewController(storyboard, animated: true)
} else {
print("error: \(String(describing: error?.localizedDescription))");
}
}
}
输出：
func getAccessToken() {
//RFC encoding of ConsumerKey and ConsumerSecretKey
let encodedConsumerKeyString:String = "sx5r...S9QRw".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
let encodedConsumerSecretKeyString:String = "KpaSpSt.....tZVGhY".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
print(encodedConsumerKeyString)
print(encodedConsumerSecretKeyString)
//Combine both encodedConsumerKeyString & encodedConsumerSecretKeyString with " : "
let combinedString = encodedConsumerKeyString+":"+encodedConsumerSecretKeyString
print(combinedString)
//Base64 encoding
let data = combinedString.data(using: .utf8)
let encodingString = "Basic "+(data?.base64EncodedString())!
print(encodingString)
//Create URL request
var request = URLRequest(url: URL(string: "https://api.twitter.com/oauth2/token")!)
request.httpMethod = "POST"
request.setValue(encodingString, forHTTPHeaderField: "Authorization")
request.setValue("application/x-www-form-urlencoded;charset=UTF-8", forHTTPHeaderField: "Content-Type")
let bodyData = "grant_type=client_credentials".data(using: .utf8)!
request.setValue("\(bodyData.count)", forHTTPHeaderField: "Content-Length")
request.httpBody = bodyData
let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(String(describing: error))")
return
}
let responseString = String(data: data, encoding: .utf8)
let dictionary = data
print("dictionary = \(dictionary)")
print("responseString = \(String(describing: responseString!))")
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
do {
let response = try JSONSerialization.jsonObject(with: data, options: []) as! Dictionary<String, Any>
print("Access Token response : \(response)")
print(response["access_token"]!)
self.accessToken = response["access_token"] as! String
self.getStatusesUserTimeline(accessToken:self.accessToken)
} catch let error as NSError {
print(error)
}
}
task.resume()
}
在这里您将获得用户名、用户ID、authtoken、authTokenSecret、屏幕名和电子邮件等
3）现在从friends/list api获取好友列表。在这里，您可以获取friends/list、users/lookup、followers/ID、followers/list api的数据等
func getStatusesUserTimeline(accessToken:String) {
let userId = "109....456"
let twitterClient = TWTRAPIClient(userID: userId)
twitterClient.loadUser(withID: userId) { (user, error) in
if user != nil {
//Get users timeline tweets
var request = URLRequest(url: URL(string: "https://api.twitter.com/1.1/friends/list.json?screen_name=KS....80&count=10")!) //users/lookup, followers/ids, followers/list
request.httpMethod = "GET"
request.setValue("Bearer "+accessToken, forHTTPHeaderField: "Authorization")
let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(String(describing: error))")
return
}
// let responseString = String(data: data, encoding: .utf8)
// let dictionary = data
// print("dictionary = \(dictionary)")
// print("responseString = \(String(describing: responseString!))")
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
do {
let response = try JSONSerialization.jsonObject(with: data, options: [])
print(response)
} catch let error as NSError {
print(error)
}
}
task.resume()
}
}
}
