iphone - iOS 4.2 相机和相册问题

Question

出于某种原因，我用来访问以前用于 iOS 的相机和相册的相同代码不起作用。每当我打开相机应用程序或相册时，应用程序都会崩溃，并且崩溃日志中没有任何内容。我针对 iOS 3.0 到 4.1 对其进行了测试，并且运行良好。有人遇到过这种情况吗？这是一个错误吗？它甚至没有到达 imagePickerController 方法，它在加载相机或相册后立即崩溃。

我使用的代码是这样的:

#pragma mark Photo methods

- (void) getNewPhoto {
 UIImagePickerController * picker = [[UIImagePickerController alloc] init];
 picker.delegate = self;
 picker.sourceType = UIImagePickerControllerSourceTypeCamera;
 [self presentModalViewController:picker animated:YES];
}

- (void)loadPhotoFromLibrary {
 UIImagePickerController * picker = [[UIImagePickerController alloc] init];
 picker.delegate = self;
 picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
 [self presentModalViewController:picker animated:YES];
}

#pragma mark ImagePickerController methods

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
 [picker dismissModalViewControllerAnimated:NO];
 selectedImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
}

谢谢!

希望你的问题得到解决，如果不试试这个......

据我所知， UIImagePickerController 不适用于 iPad ......它无法呈现任何 View Controller ，所以尝试使用 UIPopoverController(适用于 iPad)......我使用了同样的东西，它真的很好用......
