我正在開發一個twitter應用程序,我想在發送後立即顯示tweet。我試圖使用reloadData,但它不起作用。誰能幫我?謝謝!如何在發送推文後顯示推文?
這裏是我的代碼:
- (IBAction)postNewTweet:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{
SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[tweetSheet setInitialText:@""];
[self presentViewController:tweetSheet animated:YES completion:nil];
dispatch_async(dispatch_get_main_queue(), ^{
[self.tweetTableView reloadData];
});
}
else
{
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:@"Sorry"
message:@"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"
delegate:self
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alertView show];
}
}
