用户发布推文后，我需要区分他使用的是哪个推特帐户。假设用户在手机上配置了 1 个或多个帐户。
推文成功后我需要知道这一点，所以正确的地方是回调。我尝试使用 ACAccountStore 获取帐户，但它提供了一个包含手机上设置的所有帐户的数组，而不是关于最后使用的帐户的线索（甚至不是数组的顺序）。
有谁知道 TWTweetComposeViewController 是否记得这个帐户以及如何获取它？
谢谢
我的代码：
if ([TWTweetComposeViewController canSendTweet])
{
TWTweetComposeViewController *tweetSheet =
[[TWTweetComposeViewController alloc] init];
[tweetSheet setInitialText:@"initial text"];
[tweetSheet addImage:[UIImage imageNamed:image]];
// Callback
tweetSheet.completionHandler = ^(TWTweetComposeViewControllerResult result) {
// if tweet was successful
if(result == TWTweetComposeViewControllerResultDone) {
// Get the accounts
account = [[ACAccountStore alloc] init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[account requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error)
{
// if access granted I populate the array
if (granted == YES) {
NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];
ACAccount *account1 = [arrayOfAccounts objectAtIndex:0];
ACAccount *account2 = [arrayOfAccounts objectAtIndex:1];
NSString *username1 = account1.username;
NSString *username2 = account2.username;
// Always same order
NSLog(userName1);
NSLog(userName2);
}
}];
[self furtherMethodsInCaseOfSuccessfulTweet];
} else if(result == TWTweetComposeViewControllerResultCancelled) {
NSLog(@"twit canceled");
}
[self dismissViewControllerAnimated:YES completion:nil];
};
[self presentModalViewController:tweetSheet animated:YES];
}
else
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"No tweet is possible on this device" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alertView show];
}
}
