我可以通过以下方式访问用户的 Facebook:
[accStore requestAccessToAccountsWithType:fbAccountType
options:options
completion:^(BOOL granted, NSError *error) {
if (granted) {
// If access granted, then get the Facebook account info
NSArray *accounts = [accStore
accountsWithAccountType:fbAccountType];
ACAccount *acc = [accounts lastObject];
// Get the access token, could be used in other scenarios
ACAccountCredential *fbCredential = [acc credential];
NSString *accessToken = [fbCredential oauthToken];
NSLog(@"Facebook Access Token: %@", accessToken);
// Add code here to make an API request using the SLRequest class
} else {
NSLog(@"Access not granted");
}
}];
这打印出来:
Facebook Access Token: (null)
我被授予访问权限,但令牌为空。我究竟做错了什么?
谢谢
