本文介绍了presentRequestsDialogModallyWithSession 不起作用，但给出了很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
当我使用网络对话框进行好友请求时，一切都很好，除了没有请求或任何东西.代码:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:facebookFriend.id, @"to",零];[FBWebDialogs presentRequestsDialogModallyWithSession:FBSession.activeSessionmessage:NSLocalizedString(@"FB_FRIEND_INVITE_MESSAGE", @"Facebook好友邀请消息")title:NSLocalizedString(@"FB_FRIEND_INVITE_TITLE", @"Facebook好友邀请标题")参数:参数处理程序:^(FBWebDialogResult 结果，NSURL *resultURL，NSError *error){}];这是我得到的结果:
fbconnect://success?request=xxxxxxxxxxxx&to%5B0%5D=xxxxxxxx如何调试出错的地方?
提前致谢.

解决方案
对于 SDK 3.2 或更高版本，我们可以使用 FBWebDialogs 类来帮助我们展示弹出窗口以及好友列表，然后从列表中选择一个或多个以发送邀请.
让我们一步一步来:
1) 下载和设置 SDK 3.2 或更高版本.
2) 首先按照 这个 网址.
3) 然后使用附加的代码.
示例代码:(生成邀请好友请求)
-(void)inviteFriends{if ([[FBSession activeSession] isOpen]){NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];[FBWebDialogs presentRequestsDialogModallyWithSession:nil消息:[self getInviteFriendMessage]标题:无参数:参数处理程序:^(FBWebDialogResult 结果，NSURL *resultURL，NSError *error){如果(错误){[self requestFailedWithError:error];}别的{如果(结果 == FBWebDialogResultDialogNotCompleted){[self requestFailedWithError:nil];}else if([[resultURL description] hasPrefix:@"fbconnect://success?request="]){//Facebook 返回 FBWebDialogResultDialogCompleted 甚至用户//按下取消"按钮，所以我们根据//url 值，因为当我们实际时它返回请求"//完成对话框[自我请求成功];}别的{//用户取消了对话框[self requestFailedWithError:nil];}}}];}别的{/** 使用发布权限打开一个新会话*/[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:@"publish_stream"]defaultAudience:FBSessionDefaultAudienceFriends允许登录用户界面:是completionHandler:^(FBSession *session, FBSessionState 状态, NSError *error){if (!error && status == FBSessionStateOpen){NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];[FBWebDialogs presentRequestsDialogModallyWithSession:nil消息:[self getInviteFriendMessage]标题:无参数:参数处理程序:^(FBWebDialogResult 结果，NSURL *resultURL，NSError *error){如果(错误){[self requestFailedWithError:error];}别的{如果(结果 == FBWebDialogResultDialogNotCompleted){[self requestFailedWithError:nil];}else if([[resultURL description] hasPrefix:@"fbconnect://success?request="]){//Facebook 返回 FBWebDialogResultDialogCompleted 甚至用户//按下取消"按钮，所以我们根据//url 值，因为当我们实际时它返回请求"//完成对话框[自我请求成功];}别的{//用户取消了对话框[self requestFailedWithError:nil];}}}];}别的{[self requestFailedWithError:error];}}];}}这里是调用委托函数OnFBSuccess和OnFBFailed的辅助函数.
- (void)requestSucceeded{NSLog(@"requestSucceeded");id 所有者 = [fbDelegate 类];SEL 选择器 = NSSelectorFromString(@"OnFBSuccess");NSMethodSignature *sig = [owner instanceMethodSignatureForSelector:selector];_callback = [NSInvocation invocationWithMethodSignature:sig];[_callback setTarget:owner];[_callback setSelector:selector];[_callback 保留];[_callback invokeWithTarget:fbDelegate];}- (void)requestFailedWithError:(NSError *)error{NSLog(@"requestFailed");id 所有者 = [fbDelegate 类];SEL 选择器 = NSSelectorFromString(@"OnFBFailed:");NSMethodSignature *sig = [owner instanceMethodSignatureForSelector:selector];_callback = [NSInvocation invocationWithMethodSignature:sig];[_callback setTarget:owner];[_callback setSelector:selector];[_callback setArgument:&error atIndex:2];[_callback 保留];[_callback invokeWithTarget:fbDelegate];}因此调用方法InviteFriend的类必须具有以下功能:
-(void)OnFBSuccess{CCLOG(@"成功");//在这里做事【登录发布】；}-(void)OnFBFailed:(NSError *)error{如果(错误 == 零)CCLOG(@"用户已取消");别的CCLOG(@"失败");//在这里做事【登录发布】；}推荐阅读:
注意:
1) 不要忘记在 plist 中设置 Facebook 应用程序 ID.
2) 不要忘记将 AppDelegate 调整为 处理网址.
摘自上述第 2 点链接的部分片段:
/** 如果我们在 openURL 调用时有一个有效的会话，我们会处理* Facebook 通过将 url 参数传递给 handleOpenURL 进行转换*/- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)url源应用程序:(NSString *)源应用程序注释:(id)注释{//尝试从 url 中提取令牌返回 [FBSession.activeSession handleOpenURL:url];}希望有帮助！
编辑
这里:
fbDelegate 的声明是:
@property (nonatomic, assign) id fbDelegate;@protocol FBLoginDelegate @必需的-(无效)OnFBSuccess；-(void) OnFBFailed : (NSError *)error;@结尾 这就是您可以使用此代码的方式:
FBLoginHandler *login = [[FBLoginHandler alloc] initWithDelegate:self];//这里的 'self' 是你问过的 fbDelegate【登录邀请好友】；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];
