我有 UIImagePicker 来选择图像。选择图像后，我正在编辑它，现在我想保存该图像。

谁能告诉我如何将图像保存到相册中？

看看这个教程

http://iosdevelopertips.com/camera/camera-application-to-take-pictures-and-save-images-to-photo-album.html

这是我的代码获取图像如果图像被编辑，则编辑后的图像将被考虑在内。

如果未编辑，则将拍摄原始图像

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

UIImage *image;

if (picker.editing == YES) {

        image = [info objectForKey:@"UIImagePickerControllerEditedImage"];  

}
else {
        image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
}

    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);

    //  [picker release];

    //  [self dismissModalViewControllerAnimated:YES];
}

take a look at this tutorial

http://iosdevelopertips.com/camera/camera-application-to-take-pictures-and-save-images-to-photo-album.html

here is my code to get image if the image is edited then edited image will be taken into account.

if not edited then original image will be taken

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

UIImage *image;

if (picker.editing == YES) {

        image = [info objectForKey:@"UIImagePickerControllerEditedImage"];  

}
else {
        image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
}

    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);

    //  [picker release];

    //  [self dismissModalViewControllerAnimated:YES];
}

您可以使用此功能

UIImageWriteToSavedPhotosAlbum(UIImage *yourImage, id completionTarget, SEL completionSelector, void *contextInfo);

查看此问题的答案。 ..还有关于completionTarget 和completionSelector，来自文档...

completionTarget、completionSelector 和 contextInfo 的使用
参数是可选的，并且仅当您希望收到通知时才需要
当函数完成将图像写入到时异步
用户的相机胶卷或保存的照片相册。如果你不想成为
通知后，为这些参数传递 nil。

You can use this function

UIImageWriteToSavedPhotosAlbum(UIImage *yourImage, id completionTarget, SEL completionSelector, void *contextInfo);

See the answer to this question...And about completionTarget and completionSelector, from documentation...

The use of the completionTarget, completionSelector, and contextInfo
parameters is optional and necessary only if you want to be notified
asynchronously when the function finishes writing the image to the
user’s Camera Roll or Saved Photos album. If you do not want to be
notified, pass nil for these parameters.
