如何在 UIImageView、iPad 中查看从照片库弹出窗口中选择的图像

发布于 2024-10-30 22:53:35 字数 742 浏览 7 评论 0原文

我正在为 iPad 开发一个应用程序，它工作正常，直到我到达这一点：

该应用程序显示照片库的弹出窗口，但是当我选择照片时，弹出窗口不会隐藏，我也希望它能够查看UIImageView 中选定的图像，但我不知道如何。

我确信 didFinishpickingMediaWithInfo 函数有问题。这是该函数的代码：

-(void) imagePickerController:(UIImagePickerController *)picker didFinishpickingMediaWithInfo:(NSDictionary *)info{

    //bgImage is a UIImageView
bgImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

// Dismiss UIImagePickerController and release it
[picker dismissModalViewControllerAnimated:YES];
[picker.view removeFromSuperview];
[picker release];}

我的第一个问题是：我应该向该函数添加什么才能在 UIImageView 中查看所选照片？

2-我读到我应该使用 UIImage 而不是 UIImageView ..这是真的吗？如果是的话，界面构建器怎么样？没有什么叫 UIImage 吗？

非常感谢提前..:-) 问候，拉万

I am working on an application for iPad, it is working fine until i reached this point:

The app shows the popover for the photo library, but when I choose the photo, the popover doesn't hide, and I also want it to view the selected image in a UIImageView, however i do not knowhow.

I am sure there is something wrong in the didFinishpickingMediaWithInfo function.
here is the function's code:

-(void) imagePickerController:(UIImagePickerController *)picker didFinishpickingMediaWithInfo:(NSDictionary *)info{

    //bgImage is a UIImageView
bgImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

// Dismiss UIImagePickerController and release it
[picker dismissModalViewControllerAnimated:YES];
[picker.view removeFromSuperview];
[picker release];}

My first question is: What am i supposed to add to this function for viewing the selected photo in the UIImageView?

2- I have read that I should've used UIImage instead of UIImageView.. Is this true? If yes, what about the interface builder? there is nothing called UIImage ?

Many thanks in advance.. :-)

首先在 IB 中添加一个 UIImageView，在 .h 文件中为该 UIImageView 创建 IBOutlet，然后将 UIImageView 连接到 IB 中的此 IBOutlet。然后在 didFinishpickingMediaWithInfo 中获取 UIImage 实例中的 selectedImage，然后调用 setImage 到您为 UIImageView 创建的 IBOutlet 并将所选图像实例传递给 setImage。

-(void) imagePickerController:(UIImagePickerController *)picker didFinishpickingMediaWithInfo:(NSDictionary *)info{
    // TempImage is a UIImage instance
    TempImg = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    //bgImage is a UIImageView instance and it's connected in the IB
    [bgImage setImage:TempImg];
    // Dismiss UIImagePickerController and release it
    [picker dismissModalViewControllerAnimated:YES];
    [picker.view removeFromSuperview];
    [picker release];

}

我真的很抱歉打扰，并且非常感谢您抽出宝贵的时间..:-)

-(void) imagePickerController:(UIImagePickerController *)picker didFinishpickingMediaWithInfo:(NSDictionary *)info{
    // TempImage is a UIImage instance
    TempImg = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    //bgImage is a UIImageView instance and it's connected in the IB
    [bgImage setImage:TempImg];
    // Dismiss UIImagePickerController and release it
    [picker dismissModalViewControllerAnimated:YES];
    [picker.view removeFromSuperview];
    [picker release];

}

I am really sorry for bothering, and really appreciating your given time.. :-)
