本文介绍了presentRequestsDialogModallyWithSession不起作用，但给人好的结果的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我用webdialog的friendrequest，一切都进展正常，但没有要求或任何制成。
在code：
的NSMutableDictionary * PARAMS = [的NSMutableDictionary dictionaryWithObjectsAndKeys：
facebookFriend.id，@到
零];
[FBWebDialogs presentRequestsDialogModallyWithSession：FBSession.activeSession
消息：NSLocalizedString（@FB_FRIEND_INVITE_MESSAGE，@Facebook好友邀请消息）
标题：NSLocalizedString（@FB_FRIEND_INVITE_TITLE，@Facebook好友邀请题）
参数：PARAMS
处理：^（FBWebDialogResult结果，NSURL * resultURL，NSError *错误）{
}];
这是结果我得到：
<？pre> fbconnect：//成功申请= XXXXXXXXXXXX和放大器;到％5B0％5D = XXXXXXXX
我
如何调试什么错误？
先谢谢了。

解决方案
对于 SDK 3.2或以上：我们有一个设施使用 FBWebDialogs 类，这将有助于我们展现与好友列表，并沿弹出选择一个或多个列表发送邀请。
让你一步一步：
1）下载并安装<一href=\"http://stackoverflow.com/questions/14157784/can-we-invite-people-to-use-our-app-or-send-friend-request-from-the-app-via-face/16605625#16605625\">SDK 3.2 或以上。
2）首先设置你按照这个 URL。
3）然后使用附带的code。
样code：（它生成邀请好友请求）
- （无效）inviteFriends
{
如果（[FBSession activeSession] isOpen会]）
{
*的NSMutableDictionary PARAMS = [的NSMutableDictionary dictionaryWithObjectsAndKeys：无];
[FBWebDialogs presentRequestsDialogModallyWithSession：无
消息：自getInviteFriendMessage]
标题：无
参数：PARAMS
处理：^（FBWebDialogResult结果，NSURL * resultURL，NSError *误差）
{
如果（错误）
{
[个体经营requestFailedWithError：错误]
}
其他
{
如果（结果== FBWebDialogResultDialogNotCompleted）
{
[个体经营requestFailedWithError：无];
}
否则，如果（[resultURL说明】有preFIX：@fbconnect：//成功申请=]）
{
// Facebook的返回FBWebDialogResultDialogCompleted甚至用户
// presses取消按钮，所以我们区分它的基础上，
// URL值，因为它会返回请求当我们真正
//完成对话
[个体经营requestSucceeded]
}
其他
{
//用户取消对话框
[个体经营requestFailedWithError：无];
}
}
}
]; }
其他
{
/ *
*打开与发布许可的新会话
* /
[FBSession openActiveSessionWithPublishPermissions：[NSArray的arrayWithObject：@publish_stream]
defaultAudience：FBSessionDefaultAudienceFriends
allowLoginUI：YES
completionHandler：^（FBSession *会话，FBSessionState状态，NSError *误差）
{
如果（误差放大器和;！＆安培;状态== FBSessionStateOpen）
{
*的NSMutableDictionary PARAMS = [的NSMutableDictionary dictionaryWithObjectsAndKeys：无];
[FBWebDialogs presentRequestsDialogModallyWithSession：无
消息：自getInviteFriendMessage]
标题：无
参数：PARAMS
处理：^（FBWebDialogResult结果，NSURL * resultURL，NSError *误差）
{
如果（错误）
{
[个体经营requestFailedWithError：错误]
}
其他
{
如果（结果== FBWebDialogResultDialogNotCompleted）
{
[个体经营requestFailedWithError：无];
}
否则，如果（[resultURL说明】有preFIX：@fbconnect：//成功申请=]）
{
// Facebook的返回FBWebDialogResultDialogCompleted甚至用户
// presses取消按钮，所以我们区分它的基础上，
// URL值，因为它会返回请求当我们真正
//完成对话
[个体经营requestSucceeded]
}
其他
{
//用户取消对话框
[个体经营requestFailedWithError：无];
} }
}];
}
其他
{
[个体经营requestFailedWithError：错误]
}
}];
}}
和这里是调用函数代表的辅助功能 OnFBSuccess 和 OnFBFailed 。
- （无效）requestSucceeded
{
的NSLog（@requestSucceeded）;
ID所有者= [fbDelegate类]
SEL选择= NSSelectorFromString（@OnFBSuccess）;
NSMethodSignature * SIG = [所有者instanceMethodSignatureForSelector：选择];
_callback = [NSInvocation的invocationWithMethodSignature：SIG];
[_callback setTarget：所有者];
[_callback setSelector：选择];
[_callback保留] [_callback invokeWithTarget：fbDelegate];
} - （无效）requestFailedWithError：（NSError *）错误
{
的NSLog（@requestFailed）;
ID所有者= [fbDelegate类]
SEL选择= NSSelectorFromString（@OnFBFailed：）;
NSMethodSignature * SIG = [所有者instanceMethodSignatureForSelector：选择];
_callback = [NSInvocation的invocationWithMethodSignature：SIG];
[_callback setTarget：所有者];
[_callback setSelector：选择];
[_callback setArgument：放大器;错误atIndex：2];
[_callback保留] [_callback invokeWithTarget：fbDelegate];
}
所以taht调用类的方法 InviteFriend 必须具有以下功能：
- （无效）OnFBSuccess
{
CCLOG（@成功）; //在这里做的东西
[登录发布]
} - （无效）OnFBFailed：（NSError *）错误
{
如果（错误==无）
CCLOG（@用户取消）;
其他
CCLOG（@失败）; //在这里做的东西
[登录发布]
}
推荐阅读次数：
注意：
1），不要忘了安装Facebook应用程序ID在的plist 。
2）不要忘记调整的AppDelegate 来的处理的URL 。
从上面的链接2点采取局部片段：
/ *
*如果我们在通话的OpenURL的时候有效的会话，我们处理
* Facebook的转换通过传递URL参数handleOpenURL
* /
- （BOOL）应用：（*的UIApplication）的应用
的OpenURL：（NSURL *）网址
sourceApplication：（* NSString的）sourceApplication
注释：（ID）注释{
//尝试从URL中提取令牌
返回[FBSession.activeSession handleOpenURL：URL]
}
希望它帮助！
修改
下面：
声明fbDelegate是：
@属性（非原子，分配）ID＆LT; FBLoginDelegate＆GT; fbDelegate;@protocol FBLoginDelegate＆LT;＆NSObject的GT;@需要 - （无效）OnFBSuccess;
- （无效）OnFBFailed：（NSError *）错误;@结束
，这是你可以如何消费这一code：
FBLoginHandler *登录= [[FBLoginHandler页头] initWithDelegate：个体经营]; //这里的自我是你问的fbDelegate
[登录inviteFriends]
When I use the webdialog for a friendrequest, everything is going fine, except no request or anything is made. The code:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
facebookFriend.id, @"to",
nil];
[FBWebDialogs presentRequestsDialogModallyWithSession:FBSession.activeSession
message:NSLocalizedString(@"FB_FRIEND_INVITE_MESSAGE", @"Facebook friend invite message")
title:NSLocalizedString(@"FB_FRIEND_INVITE_TITLE", @"Facebook friend invite title")
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
}];
This is the result I get:
fbconnect://success?request=xxxxxxxxxxxx&to%5B0%5D=xxxxxxxx
How can I debug what is going wrong?
Thanks in advance.

解决方案
For SDK 3.2 or above we have a facility to use FBWebDialogs class that will help us to show a popup along with the friend list and pick one or more from list to send invitation.
Lets do it step by step:
1) Download and setup SDK 3.2 or above.
2) First setup your application on facebook by following this url.
3) Then use the attached code.
Sample Code: (It generates invite friend request)
-(void)inviteFriends
{
if ([[FBSession activeSession] isOpen])
{
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:[self getInviteFriendMessage]
title:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
{
if (error)
{
[self requestFailedWithError:error];
}
else
{
if (result == FBWebDialogResultDialogNotCompleted)
{
[self requestFailedWithError:nil];
}
else if([[resultURL description] hasPrefix:@"fbconnect://success?request="])
{
// Facebook returns FBWebDialogResultDialogCompleted even user
// presses "Cancel" button, so we differentiate it on the basis of
// url value, since it returns "Request" when we ACTUALLY
// completes Dialog
[self requestSucceeded];
}
else
{
// User Cancelled the dialog
[self requestFailedWithError:nil];
}
}
}
];
}
else
{
/*
* open a new session with publish permission
*/
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:@"publish_stream"]
defaultAudience:FBSessionDefaultAudienceFriends
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error)
{
if (!error && status == FBSessionStateOpen)
{
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:[self getInviteFriendMessage]
title:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
{
if (error)
{
[self requestFailedWithError:error];
}
else
{
if (result == FBWebDialogResultDialogNotCompleted)
{
[self requestFailedWithError:nil];
}
else if([[resultURL description] hasPrefix:@"fbconnect://success?request="])
{
// Facebook returns FBWebDialogResultDialogCompleted even user
// presses "Cancel" button, so we differentiate it on the basis of
// url value, since it returns "Request" when we ACTUALLY
// completes Dialog
[self requestSucceeded];
}
else
{
// User Cancelled the dialog
[self requestFailedWithError:nil];
}
}
}];
}
else
{
[self requestFailedWithError:error];
}
}];
}
}
and here are the helper functions that calls delegates function OnFBSuccess and OnFBFailed.
- (void)requestSucceeded
{
NSLog(@"requestSucceeded");
id owner = [fbDelegate class];
SEL selector = NSSelectorFromString(@"OnFBSuccess");
NSMethodSignature *sig = [owner instanceMethodSignatureForSelector:selector];
_callback = [NSInvocation invocationWithMethodSignature:sig];
[_callback setTarget:owner];
[_callback setSelector:selector];
[_callback retain];
[_callback invokeWithTarget:fbDelegate];
}
- (void)requestFailedWithError:(NSError *)error
{
NSLog(@"requestFailed");
id owner = [fbDelegate class];
SEL selector = NSSelectorFromString(@"OnFBFailed:");
NSMethodSignature *sig = [owner instanceMethodSignatureForSelector:selector];
_callback = [NSInvocation invocationWithMethodSignature:sig];
[_callback setTarget:owner];
[_callback setSelector:selector];
[_callback setArgument:&error atIndex:2];
[_callback retain];
[_callback invokeWithTarget:fbDelegate];
}
So the class taht calls method InviteFriend MUST have these functions:
-(void)OnFBSuccess
{
CCLOG(@"successful");
// do stuff here
[login release];
}
-(void)OnFBFailed:(NSError *)error
{
if(error == nil)
CCLOG(@"user cancelled");
else
CCLOG(@"failed");
// do stuff here
[login release];
}
Recommended Reads:
NOTE:
1) Don't forget to setup Facebook application ID in plist.
2) Don't forget to adjust AppDelegate to handle urls.
Partial snippet taken from above link in point 2:
/*
* If we have a valid session at the time of openURL call, we handle
* Facebook transitions by passing the url argument to handleOpenURL
*/
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
// attempt to extract a token from the url
return [FBSession.activeSession handleOpenURL:url];
}
Hope it helps!
EDIT
Here:
declaration for fbDelegate is:
@property (nonatomic, assign) id <FBLoginDelegate> fbDelegate;
@protocol FBLoginDelegate <NSObject>
@required
-(void) OnFBSuccess;
-(void) OnFBFailed : (NSError *)error;
@end
and this is how you can consume this code:
FBLoginHandler *login = [[FBLoginHandler alloc] initWithDelegate:self]; // here 'self' is the fbDelegate you have asked about
[login inviteFriends];
