在 iPhone 中显示图库中的图像

我是 iPhone 新手，现在正处于学习阶段。实际上我想实现读取存储在 iPhone PHOTO Gallery 中的图像，然后将其显示到我的应用程序上。

我在很多搜索引擎中进行了搜索，但找不到任何东西。你们这里都是专业人士。请指导我完成一些代码或教程。

多谢

Edit

另请查看此问题/答案以及用于从中获取图像的方法uiimagepickercontroller因为我之前提到的方法已被弃用。

didFinishPickingMediaWithInfo 返回零照片 https://stackoverflow.com/questions/3088874/didfinishpickingmediawithinfo-return-nil-photo/4192109

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

它有大约相同的示例。

您可以使用这些方法来获取 UIImageView 对象中的图像

- (void)selectPhotos
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    picker.delegate = self;
    [self presentViewController:picker animated:YES completion:nil];
    //Deprecated In IOS6[self presentModalViewController:picker animated:YES]; 
    [picker release];
}

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