Ios 由于-[FBSession checkThreadAffinity]、';FBSession:只能从单个线程使用';
我在应用程序中使用facebook SSON。当我调用我的方法[self-openSessionWithAllowLoginUI:NO]时;在块内,它将崩溃,并显示以下错误消息Ios 由于-[FBSession checkThreadAffinity]、';FBSession:只能从单个线程使用';,ios,facebook,thread-safety,Ios,Facebook,Thread Safety,我在应用程序中使用facebook SSON。当我调用我的方法[self-openSessionWithAllowLoginUI:NO]时;在块内,它将崩溃,并显示以下错误消息 *** Assertion failure in -[FBSession checkThreadAffinity], /Users/chrisp/tmp/build-sdk/ios-sdk/src/FBSession.m:1571 Terminating app due to uncaught exceptio

我知道它说的是我从两个或多个线程调用FBSession,我应该从一个线程调用它,但是我没有得到我调用这个线程的其他地方
我的代码是:-
-(void)facebook
{
ACAccountStore *accountStore;
accountStore = [[ACAccountStore alloc]init];
ACAccountType *FBaccountType= [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:kFACEBOOK_APPID,ACFacebookAppIdKey,@[@"email"],ACFacebookPermissionsKey, nil];
[accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
^(BOOL granted, NSError *e) {
if (granted)
{
NSArray *accounts = [accountStore accountsWithAccountType:FBaccountType];
if ([accounts count] == 0) {
}
else{
ACAccount *facebookAccount;
NSLog(@"Facebook account Found");
facebookAccount = [accounts firstObject];
ACAccountCredential *facebookCredential = [facebookAccount credential];
NSString *accessToken = [facebookCredential oauthToken];
NSLog(@"Facebook Access Token: %@", accessToken);
NSLog(@"facebook account =%@",facebookAccount);
}
}
else
{
NSLog(@"error getting permission %@",e);
[self openSessionWithAllowLoginUI:NO];
}
}];
}
但是,如果我不是从块中的调用,它工作正常,但是我需要直接从需要在块中调用它的设置应用程序实现Facebook SSO
没有阻塞,我这样称呼它:
-(void)facebook
{
ACAccountStore *accountStore;
accountStore = [[ACAccountStore alloc]init];
ACAccountType *FBaccountType= [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:kFACEBOOK_APPID,ACFacebookAppIdKey,@[@"email"],ACFacebookPermissionsKey, nil];
[self openSessionWithAllowLoginUI:NO];
}
如果您需要更多的代码,请告诉我。试试看
dispatch_async(dispatch_get_main_queue(), ^{
[self openSessionWithAllowLoginUI:NO];
});
你能把代码行放在调用方法的地方吗?
facebook
?我只需点击一个按钮就可以调用它。尝试执行dispatch_async(dispatch_get_main_queue(),^{[self openSessionWithAllowLoginUI:NO];});多谢了,伙计,它起作用了。完美的请加上它作为答案。我已加上它作为答案。。
