目標C - 回調的UIImagePickerController

Question

我執行的UIImagePickerController的

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 

委託方法。

如何確定在該方法中，如果回調來自UIImagePickerControllerSourceTypeCamera或UIImagePickerControllerSourceTypePhotoLibrary？

感謝，

應該很簡單：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
    if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) { 
     // ... 
    } 
}
