这篇博客介绍了如何在iOS应用中调用照相机和相册功能。对于iPhone设备，重点讲解了使用UIImagePickerController代理方法`imagePickerController:didFinishPickingMediaWithInfo:`来处理选择的媒体信息，以及`imagePickerControllerDidCancel:`方法来捕获用户取消操作的情况。

打开相机：

//先设定sourceType为相机，然后判断相机是否可用（ipod）没相机，不可用将sourceType设定为相片库
    UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypeCamera;
//    if (![UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) {
//        sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
//    }
    //sourceType = UIImagePickerControllerSourceTypeCamera; //照相机
    //sourceType = UIImagePickerControllerSourceTypePhotoLibrary; //图片库
    //sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; //保存的相片
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];//初始化
    picker.delegate = self;
    picker.allowsEditing = YES;//设置可编辑
    picker.sourceType = sourceType;
    [self presentModalViewController:picker animated:YES];//进入照相界面
    [picker release];

打开相册：（区分pad和iphone）
