iphone - iOS 相机捕捉 View 已经？

Question

我想要一个相机 View ，可以将图像捕获到本地文件或让用户从本地照片库中选择图像。我想也许有人为此编写了很好的库/代码。也许我可以利用它。已经有好的了吗？谢谢。我只是避免重新发明轮子:)

UIImagePickerController 内置于 iOS 中并且非常易于使用，它可以提供您想要的所有功能。

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImagePickerController_Class/UIImagePickerController/UIImagePickerController.html

对于用户拍摄新照片:

"UIImagePicker *imagePicker"

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES)
{
    imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;
    imagePicker.delegate = self;
    imagePicker.allowsEditing = NO;
    imagePicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
    imagePicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentModalViewController:imagePicker animated:YES];
}

或者从设备中选择现有照片:

if( ![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum] ) return;

imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.allowsEditing = NO;

[self presentModalViewController:imagePicker animated:YES];

一定要包括这个!

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    [self dismissModalViewControllerAnimated:YES];
}
