一个UIImagePickerController的故事：如何抓住图片插入推文？

我必须在推文中添加图片。我试过这个代码，只有选择器显示。当我不会抢在图像上点击...这里是代码：一个UIImagePickerController的故事：如何抓住图片插入推文？

- (IBAction)sendImageTweet:(id)sender { 
    UIImagePickerController *picker = [[UIImagePickerController alloc] init]; 
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    picker.delegate = self; 
    picker.allowsEditing = NO; 
    [self presentModalViewController:picker animated:YES]; 
} 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init]; 
    UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; 
    [self dismissModalViewControllerAnimated:YES]; 
    [tweetViewController addImage:(UIImage *)image]; 
    [self presentModalViewController:tweetViewController animated:YES]; 
}

谢谢，对不起我的英语...

我认为这个问题是你是一个驳回的viewController，并在同一时间呈现一个。我这样做

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
[self dismissModalViewControllerAnimated:YES]; 
UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; 
[self performSelector: @selector(showTweetwithPhoto:) withObject: image afterDelay: 0.5]; 

}

和它的工作完美

-(void) showTweetwithPhoto:(UIImage*)image { 
    TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init]; 
    [tweetViewController addImage:image]; 
    [self presentModalViewController:tweetViewController animated:YES]; 
}

尝试铸造的图像数据（通过返回的UIImagePickerController）到UIImage对象，如下所示。（我改变了第二行代码）。

UIImage *image = (UIImage*)[info objectForKey:@"UIImagePickerControllerOriginalImage"];

谢谢，这是行不通的...... – 2012-01-27 18:32:54

UIImage * image = (UIImage *) [info valueForKey:UIImagePickerControllerOriginalImage];
