我正在向 facebook 朋友发送应用请求，那么如何在 UIWebView 中打开应用请求？

NSDictionary *parametersDict = @{@"to":@""};

对于邀请用户，您可以在添加 facebook-sdk 后使用以下代码

[FBWebDialogs
 presentRequestsDialogModallyWithSession:nil
message:@"Your invite message"
title:nil
parameters:nil
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                                      if (error) {
                                          // An error occurred, we need to handle the error
                                          // See: https://developers.facebook.com/docs/ios/errors
                                          NSLog(@"Error publishing story: %@", error.description);
                                      } else {
                                          if (result == FBWebDialogResultDialogNotCompleted) {
                                              // User canceled.
                                              NSLog(@"User cancelled.");
                                          } else {
                                              // Handle the publish feed callback




                                              } 

                                    }


}];

在 webview 中显示应用请求：发送您朋友的 facebookId 和您的消息。

- (void)sendAppRequestToFacebookFriend:(NSString*)message andFacebookId:(NSString*)friendFBId {


NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                message, @"message",
                               @"", @"redirect_url",
                               friendFBId,@"to",
                               nil];


[FBWebDialogs
 presentRequestsDialogModallyWithSession:nil
 message:message
 title:@"App Title App"
 parameters:params
 handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {

     if (!error) {


         if (result == FBWebDialogResultDialogNotCompleted) {





         }
         else if([[resultURL description] hasPrefix:@"fbconnect://success?request="]) {
             //code after success
            } 

     } 

 }
  ];
