iphone - 如何在我的应用程序中实现 "Choose Existing Photo"，就像在默认的 iphone 电话簿中一样？

Question

我想开发一个应用程序，它的功能与iphone电话簿一样，可以捕获图像并选择图像，

我应该用什么来做这样的事

我为 UIActionSheet 制作了一个 UIImageView 和一个按钮，

现在我想在我的应用程序中执行“拍照”和“选择现有照片”选项

帮帮我，我很感激

提前致谢....

嘿@Veer 你需要使用 UIImagePickerController

查看文档 http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImagePickerController_Class/UIImagePickerController/UIImagePickerController.html并查看此链接

它有大致相同的示例。

编辑您可以使用这些方法在您的 UIImageView 对象中获取图像

- (void)selectPhotos
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    picker.delegate = self;
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

- (void)imagePickerController:(UIImagePickerController *)picker
        didFinishPickingImage:(UIImage *)image
                  editingInfo:(NSDictionary *)editingInfo
{
    imageView.image = image;
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];
}
