私はいくつかのコードをコピーしましたアップルのドキュメント- 次の 2 つのエラーが発生しました:
Undefined symbols for architecture i386:
"_kUTTypeImage", referenced from:
-[ImagePicker imagePickerController:didFinishPickingMediaWithInfo:] in ImagePicker.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
何が間違っているのでしょうか?
編集: コード:
- (IBAction) showSavedMediaBrowser {
[self startMediaBrowserFromViewController: self
usingDelegate: (id)self];
}
- (BOOL) startMediaBrowserFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
// Displays saved pictures and movies, if both are available, from the
// Camera Roll album.
mediaUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeSavedPhotosAlbum];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
mediaUI.allowsEditing = YES;
mediaUI.delegate = delegate;
[controller presentViewController:mediaUI animated:YES completion:nil];
return YES;
}
- (void) imagePickerController: (UIImagePickerController *) picker
didFinishPickingMediaWithInfo: (NSDictionary *) info {
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
UIImage *originalImage, *editedImage, *imageToUse;
// Handle a still image picked from a photo album
if (CFStringCompare ((__bridge_retained CFStringRef) mediaType, kUTTypeImage, 0)
== kCFCompareEqualTo) {
editedImage = (UIImage *) [info objectForKey:
UIImagePickerControllerEditedImage];
originalImage = (UIImage *) [info objectForKey:
UIImagePickerControllerOriginalImage];
if (editedImage) {
imageToUse = editedImage;
} else {
imageToUse = originalImage;
}
// Do something with imageToUse
}
[[picker parentViewController] dismissModalViewControllerAnimated: YES];
}
エラーは最後のメソッドが始まるところにあると思いますが、よく分かりません。
投稿にはコードセクションを説明するコンテキストがあまりありません。シナリオをもっと明確に説明してください。

シンボル ( kUTTypeImage) を検索し、それが存在するはずのイメージ/ライブラリ (MobileCoreServices.frameworkこの場合は ) を見つけます。次に、バイナリをそのフレームワークにリンクします。
