ios - 格式化 URL 以在 Facebook 帖子中显示为字符串

Question

我正在尝试在 facebook 上发布一个格式化为字符串的链接。请看下面的相关代码:

NSMutableDictionary* params = [[NSMutableDictionary alloc] init];

NSString *modifiedTitle = [NSString stringWithFormat:@"<a href= https://www.google.com> My App </a>"];
[params setObject:modifiedTitle forKey:@"message"];
[params setObject:UIImagePNGRepresentation(picture) forKey:@"picture"];


[FBRequestConnection startWithGraphPath:@"me/photos"
                             parameters:params
                             HTTPMethod:@"POST"
                      completionHandler:^(FBRequestConnection *connection,
                                          id result,
                                          NSError *error)
         if (error)
     {
         //showing an alert for failure
         NSLog(@"ERROR in posting image to Facebook");
     }
     else
     {
         //showing an alert for success
         NSLog(@"Result after posting image successfully = %@",result);
     }
     // button.enabled = YES;
 }];

消息显示为:

<a href= https://www.google.com> My App </a>

代替

My App

一方面，确保您使用复制方法将不可变字典发布到 startWithGraph... 方法中:

NSDictionary* paramsImmutable = params.copy;
[FBRequestConnection startWithGraphPath:@"me/photos"
                         parameters:paramsImmutable
                         HTTPMethod:@"POST"
                  completionHandler:^(FBRequestConnection *connection,
                                      id result,
                                      NSError *error)

这样一来，在方法的生命周期内，您就不必担心该对象的任何更改。

接下来，您的参数是否包括 url 周围的任何引号？即

NSString *modifiedTitle = @"<a href='https://www.google.com'>My App</a>";

这只是一个开始。
