アカウント ストアをセットアップする方法を既に知っている場合は、アクセス トークンを取得する方法を示すコードを次に示します。
@property (strong, nonatomic) ACAccountStore *accountStore;
@property (strong, nonatomic) ACAccount *fbAccount;
...
@synthesize accountStore = _accountStore;
@synthesize fbAccount = _fbAccount;
...
// Initialize the account store
self.accountStore = [[ACAccountStore alloc] init];
// Get the Facebook account type for the access request
ACAccountType *fbAccountType = [self.accountStore
accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
// Request access to the Facebook account with the access info
[self.accountStore requestAccessToAccountsWithType:fbAccountType
options:fbInfo
completion:^(BOOL granted, NSError *error) {
if (granted) {
// If access granted, then get the Facebook account info
NSArray *accounts = [self.accountStore
accountsWithAccountType:fbAccountType];
self.fbAccount = [accounts lastObject];
// Get the access token, could be used in other scenarios
ACAccountCredential *fbCredential = [self.fbAccount 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");
}
}];
