如何使用我的iPhone应用程序拍照？
我正在用Cocoa在xcode中编写一个iPhone应用程序。我找不到任何教程或示例代码来展示如何使用内置相机拍照。我该怎么做呢？我在哪里可以找到好的信息？
谢谢!

使用UIImagePickerController。这里有一个很好的教程。

您应该将源类型设置为UIImagePickerControllerSourceTypeCamera或UIImagePickerControllerSourceTypePhotoLibrary。请注意，这两种类型在屏幕上的显示截然不同。您应该仔细测试这两种方法。特别是，如果您将UIImagePickerController嵌套在UINavigationController中，如果您不小心，您可能会得到多个导航栏和其他奇怪的效果。

UIImagePickerController类允许您拍摄照片或从照片库中选择照片。将源类型指定为UIImagePickerControllerSourceTypeCamera。

@WQS发布的答案运行良好，但包含一些iOS 6中已弃用的方法。以下是iOS 6及以上版本的更新答案：
-(void)takePhoto
{
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
[imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
}
// image picker needs a delegate,
[imagePickerController setDelegate:self];
// Place image picker on the screen
[self presentViewController:imagePickerController animated:YES completion:nil];
}
-(void)chooseFromLibrary
{
UIImagePickerController *imagePickerController= [[UIImagePickerController alloc]init];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
// image picker needs a delegate so we can respond to its messages
[imagePickerController setDelegate:self];
// Place image picker on the screen
[self presentViewController:imagePickerController animated:YES completion:nil];
}
//delegate methode will be called after picking photo either from camera or library
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissViewControllerAnimated:YES completion:nil];
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
[myImageView setImage:image]; // "myImageView" name of any UImageView.
}不要忘记在您的view controller.h中添加以下内容：
@interface myVC<UINavigationControllerDelegate, UIImagePickerControllerDelegate>https://stackoverflow.com/questions/123503
