iOS相機已捕獲視圖？

Question

我想要一個可以將圖像捕獲到本地文件或讓用戶從本地相冊中選擇圖像的相機視圖。 我認為也許有人為此編寫了不錯的庫/代碼。 也許我可以利用它。 已經有好東西了嗎？ 謝謝。 我只是在避免重新發明輪子:)

UIImagePickerController內置於iOS中，非常易於使用，它可以滿足您所需的所有功能。

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

供用戶拍攝新照片：

“ 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];
}

或從設備中選擇現有照片：

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

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

[self presentModalViewController:imagePicker animated:YES];

一定要包括這個！

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