Question

我想要一个能够将图像捕获到本地文件的摄像机视图，或者让用户从本地照片库中选择一个图像。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。有没有好的？谢谢。我只是避免重新发明轮子：）

UIImagePickerController内置于iOS中，非常易于使用，它可以实现您想要的所有功能。

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

让用户拍摄新照片：

“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];

请务必加入此内容！

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

iOS相机捕捉视图已经？
