2.获取SDK，在github上下载的工程打开进行编译获取对应的framework

3.将SDK加入项目中

• 将下列代码加到info.plist中

  <key>LSApplicationQueriesSchemes</key>
  <array>
      <string>vk</string>
      <string>vk-share</string>
      <string>vkauthorize</string>
  </array>
  

  添加成功后如下所示

• 在info中，URL Types添加如下内容，其中Identifier和URL Schemes为vk+VK后台创建的应用ID

• 在需要调用的地方导入#import <VKSdkFramework/VKSdkFramework.h>

  #import <VKSdkFramework/VKSdkFramework.h>
  

• SDK初始化

  1.将代码放入应用程序委托方法里

  - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
      [VKSdk processOpenURL:url fromApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]];
      return YES;
  }
  

  注意：如果您已经添加了FaceBook SDK，并且返回了其中一种方法[FBSDKDelegate ...]，则可以对其进行处理

  -(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
  
      [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation];
      [VKSdk processOpenURL:url fromApplication:sourceApplication];
      return YES;
  }
  

  3.在需要调用的页面

  - (**void**)viewDidLoad {
    [super viewDidLoad];
  
    [[VKSdk initializeWithAppId:@"3974615"] registerDelegate:self];
      [[VKSdk instance] setUiDelegate:self];
      SCOPE = @[VK_PER_FRIENDS, VK_PER_EMAIL];
      [VKSdk wakeUpSession:SCOPE completeBlock:^(VKAuthorizationState state, NSError *error) {
          NSLog(@"state:%lu",(unsigned long)state);
          if (state == VKAuthorizationAuthorized) {
              NSLog(@"可以登录");
              
          } else if (error) {
              NSLog(@"发生错误:%@",error.description);
              
          }
      }];
  }
  

  4.添加delegate

  <VKSdkUIDelegate,VKSdkDelegate>
  

  5.在点击VK登录的方法里调用如下方法

  [VKSdk authorize:SCOPE];
  

  6.实现代理方法

  - (void)vkSdkAccessAuthorizationFinishedWithResult:(VKAuthorizationResult *)result {
      
      if (result.token) {
          NSLog(@"userid:%@",result.token.userId);
          NSLog(@"accessToken:%@",result.token.accessToken);
          //登录成功，获取到userId，执行后续操作（如登录等）
          
      } else if (result.error) {//失败
          NSLog(@"error:%@",result.error.description);
      }
  }
  
  - (void)vkSdkNeedCaptchaEnter:(VKError *)captchaError {
      VKCaptchaViewController *vc = [VKCaptchaViewController captchaControllerWithError:captchaError];
      [vc presentIn:self];
  }
  
  - (void)vkSdkTokenHasExpired:(VKAccessToken *)expiredToken {
      [VKSdk authorize:SCOPE];
  }
  
  - (void)vkSdkUserAuthorizationFailed {
      NSLog(@"failed");
  }
  
  - (void)vkSdkShouldPresentViewController:(UIViewController *)controller {
      [self presentViewController:controller animated:YES completion:nil];
  }
  

注：

如果没有装VK APP，点击VK登录没有提示，暂没做处理
