我正在向facebook好友发送应用程序请求，那么如何在UIWebView中打开应用程序请求？

要邀请用户，添加facebook sdk后可以使用以下代码

[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中显示应用程序请求：发送朋友的facebookId和消息

- (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
            } 

     } 

 }
  ];

}

没关系，但是如何将此url传递到webview。如何在webview中打开应用程序请求。嘿，兄弟！！！我有FacebookHelper.h&m文件和sharedFacebookHelper.session，甚至未声明标识符作为错误，该怎么办？在-presentRequestsDialogModallyWithSession的块中：sharedFacebookHelper.delegate.session，我获取了“shareFacebookHelper.delegate.session”的未声明标识符。崩溃：由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“-[FBDialog initWithURL:params:isViewInvisible:frictionlessSettings:delegate:：未识别的选择器发送到实例0x78ed0260”。

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


[FBWebDialogs
 presentRequestsDialogModallyWithSession:nil

     if (!error) {


         if (result == FBWebDialogResultDialogNotCompleted) {





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

     }
