一個UIImagePickerController的故事：如何抓住圖片插入推文？

我必須在推文中添加圖片。我試過這個代碼，只有選擇器顯示。當我不會搶在圖像上點擊...這裏是代碼：一個UIImagePickerController的故事：如何抓住圖片插入推文？

- (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]; 
}

謝謝，對不起我的英語...

我認爲這個問題是你是一個駁回的viewController，並在同一時間呈現一個。我這樣做

- (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]; 
}

謝謝，它的工作！ :) – 2012-01-27 20:15:25

嘗試鑄造的圖像數據（通過返回的UIImagePickerController）到UIImage對象，如下所示。（我改變了第二行代碼）。

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

謝謝，這是行不通的...... – 2012-01-27 18:32:54

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