我试图在Swift中以编程方式设置UIView的自定义边框颜色.

这是我的代码,我只获取用户名和用户的Facebook ID.

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    [login
     logInWithReadPermissions: @[@"public_profile",@"email",@"user_friends"]
     fromViewController:self
     handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
         if (error) {
             NSLog(@"Process error");
         } else if (result.isCancelled) {
             NSLog(@"Cancelled");
         } else {

             if ([FBSDKAccessToken currentAccessToken]) {
                 [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
                  startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                      if (!error) {
                          NSLog(@"fetched user:%@", result);
                      }
                  }];
             }             NSLog(@"Results=%@",result);
             NSLog(@"Logged in");
         }
     }];

它也会给出一些像这样的错误 -

-canOpenURL:URL失败:"fbauth2:/" - 错误:"(null)" - scanOpenURL:URL失败:"fbauth2:/" - 错误:"(null)"

FBSDKLog:从Graph API v2.4开始,对/ me的GET请求应该包含一个显式的"fields"参数
