我的代码按预期工作，只是我需要删除此警告消息.
这是我的示例代码.
if ([TWTweetComposeViewController canSendTweet]) {
// Initialize Tweet Compose View Controller
TWTweetComposeViewController *vc = [[TWTweetComposeViewController alloc] init];
// Settin The Initial Text
[vc setInitialText:@"This tweet was sent using the new Twitter framework available in iOS 5."];
// Adding an Image
UIImage *image = [UIImage imageNamed:@"sample.jpg"];
[vc addImage:image];
// Adding a URL
NSURL *url = [NSURL URLWithString:@"http://mobile.tutsplus.com"];
[vc addURL:url];
// Setting a Completing Handler
[vc setCompletionHandler:^(TWTweetComposeViewControllerResult result) {
[self dismissModalViewControllerAnimated:YES];
}];
// Display Tweet Compose View Controller Modally
[self presentViewController:vc animated:YES completion:nil];
} else {
// Show Alert View When The Application Cannot Send Tweets
NSString *message = @"The application cannot send a tweet at the moment. This is because it cannot reach Twitter or you don't have a Twitter account associated with this device.";
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oops" message:message delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
[alertView show];
}
