接入Twitter

具体查看上面链接

创建应用

1、创建应用
进入网址：https://apps.twitter.com/ 创建应用，获得key，secret，勾选
Allow this application to be used to Sign in with Twitter

2、在Callback URLs添加 twitterkit-consumerkey://
不然会返回下面的错误

[TwitterKit] Error obtaining user auth token.
error: Request failed: forbidden (403)

工程配置

1、库文件导入
这个链接里，获取SDKTwitterSDK获取
下载引入库文件

TwitterCore.framework
TwitterKit.framework
TwitterKitResources.bundle

需要而外添加

SafariServices.framework
//如果工程配置了Other Linker Flags为-ObjC的话需要添加下面两个库文件
CoreLocation.framework
MapKit.framework

2、Info.plist配置
配置URL types和LSApplicationQueriesSchemes

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>twitterkit-<consumerKey></string>
    </array>
  </dict>
</array>
<key>LSApplicationQueriesSchemes</key>
<array>
    <string>twitter</string>
    <string>twitterauth</string>
</array>

代码调用

一、SDK初始化

在Appdelegate里添加

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
    return [[Twitter sharedInstance] application:app openURL:url options:options];
}

TwitterSDK初始化，要在调用登录之前调用

[[TWTRTwitter sharedInstance] startWithConsumerKey:@"6UFxIZuZIhAy4Mi8xxxxxxxx" consumerSecret:@"MmOJhdd13jR5a3TmEpey5RdXVXBG6qNJZpES4rFXhxxxxxxxx"];

二、使用Twitter按钮登录

TWTRLogInButton *logInButton = [TWTRLogInButton buttonWithLogInCompletion:^(TWTRSession *session, NSError *error) {
    if (session) {
        NSLog(@"signed in as %@", [session userName]);
        NSLog(@"signed in as %@", [session userID]);
        NSLog(@"signed in as %@", [session authToken]);
        NSLog(@"signed in as %@", [session authTokenSecret]);
        
    } else {
        NSLog(@"error: %@", [error localizedDescription]);
    }
}];

三、使用自定义Button

- (IBAction)loginWithTwitter:(UIButton *)sender {

    TWTRSession *session = [[Twitter sharedInstance] sessionStore].session;
    if(session) {
        //如果已经授权过了，判断session是否为空，直接返回用户信息。
        NSLog(@"userName  = %@", [session userName]);
        NSLog(@"userID  = %@", [session userID]);
        NSLog(@"authToken  = %@", [session authToken]);
        NSLog(@"authTokenSecret  = %@", [session authTokenSecret]);
        self->_userId = [session userID];
        
        return;
    }
    
    [[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session, NSError *error) {
        if (session) {
            NSLog(@"userName  = %@", [session userName]);
            NSLog(@"userID  = %@", [session userID]);
            NSLog(@"authToken  = %@", [session authToken]);
            NSLog(@"authTokenSecret  = %@", [session authTokenSecret]);
            self->_userId = [session userID];
            
        } else {
            NSLog(@"error: %@", [error localizedDescription]);
        }
    }];
}

四、注销账号

Twitter账号注销

- (IBAction)logout:(id)sender {
    if(_userId) {
        [[[Twitter sharedInstance] sessionStore] logOutUserID:_userId];
    }
}

常见问题

如果在Other Linker Flags里面添加了-ObjC
就会出现下面这个错误
解决办法就是单独对需要加-ObjC标记的库，单独引用
使用-force_load+framewrok目录
-force_load$(PROJECT_DIR)/xxx/xxx/xxx.framework/xxx

或者添加

CoreLocation.framework
MapKit.framework

错误提示如下

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_CLLocationManager", referenced from:
      objc-class-ref in TwitterKit(TWTRSETweetComposerViewController.o)
  "_OBJC_CLASS_$_MKMapView", referenced from:
      objc-class-ref in TwitterKit(TWTRSELocationMapTableViewHeaderView.o)
  "_MKCoordinateRegionMakeWithDistance", referenced from:
      -[TWTRSELocationMapTableViewHeaderView initWithCenterCoordinates:] in TwitterKit(TWTRSELocationMapTableViewHeaderView.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

iOS使用Twitter登录应用
