iphone - 如何以编程方式查看相册中的照片？

Question

我使用以下代码从相册中获取图像。

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[imagePicker setDelegate:self];
[self presentModalViewController:imagePicker animated:YES];

和

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{
    [picker dismissModalViewControllerAnimated:YES];
    [picker release];

    // Edited image works great (if you allowed editing)
    //myUIImageView.image = [info objectForKey:UIImagePickerControllerEditedImage];
    // AND the original image works great
    //myUIImageView.image = [info objectForKey:UIImagePickerControllerOriginalImage];
    // AND do whatever you want with it, (NSDictionary *)info is fine now
    //UIImage *myImage = [info objectForKey:UIImagePickerControllerEditedImage];

    UIImage *image =  [info objectForKey:UIImagePickerControllerOriginalImage];

    [customImageView setImage:image]; 

    customImageView.contentMode = UIViewContentModeScaleAspectFill;
}

但我没有得到设备的任何回应。我已经完成了所有 SO 答案，但它对我不起作用。谁能告诉我如何从相册中获取图像。

从方法中删除您的release声明。didFinishPickingMediaWithInfo写成

[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
