我正在尝试在我的 iOS 6 应用程序中将图像添加到推文表中。我有一个小问题。一旦用户从照片库中选择了图像，我想显示 TweetSheet 但我收到以下警告：

警告：在演示过程中尝试继续演示！

如何在照片库的关闭动画完成后显示 Tweet Sheet？

这是我的代码：

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
image = [info objectForKey:UIImagePickerControllerOriginalImage];
[self dismissViewControllerAnimated:YES completion:nil];

[self tweet_image];
}

-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [self dismissViewControllerAnimated:YES completion:nil];
}

-(void)tweet_image {
    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {

    SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
    [tweetSheet setInitialText:[NSString stringWithFormat: @"@%@ ", USERNAME]];
    [tweetSheet addImage:image];
    [self presentViewController:tweetSheet animated:YES completion:nil];
}

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 in iOS settings." delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
    [alertView show];
}

}

谢谢，丹。

【解决方案1】：

将您对 -tweet_image 的调用放在 -dismissViewControllerAnimated 的完成块中：

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    image = [info objectForKey:UIImagePickerControllerOriginalImage];
    [self dismissViewControllerAnimated:YES completion:^ {
        [self tweet_image];
    }];
}

我想出了一个办法。我决定用图像制作一个确认屏幕，然后从那里显示推文表。
