UIImagePickerController出错
UIImagePickerController出错
提问于 2012-01-26 02:10:15
我有这个代码在推特上发送图像。当我尝试这个应用程序时，拾取器工作得很好，但它不能捕获图像。怎么了？
- (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"];
NSData *imageData = UIImagePNGRepresentation(image);
[self dismissModalViewControllerAnimated:YES];
[tweetViewController addImage:(UIImage *)imageData];
[self presentModalViewController:tweetViewController animated:YES];

您应该使用常量，而不是NSString和键。
