这段代码对我有用，试试看也许对你有帮助

    - (void) openPhotoLibrary {
        NSLog(@"openPhotolibrary");

        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
            if (self.picker != nil) {
                NSLog(@"releasing self.picker...");
                [self.picker release];
            }
            self.picker = [[UIImagePickerController alloc] init];
            self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            //self.picker.allowsImageEditing = YES;
            [self.picker presentModalViewController:self.picker animated:YES];
            self.picker.delegate = self;

            [[[CCDirector sharedDirector] openGLView] addSubview:self.picker.view];
        }
    }

    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)currentPicker {
        NSLog(@"imagePickerControllerDidCancel");

        // hide the self.picker if user cancels picking an image.
        [currentPicker dismissModalViewControllerAnimated:YES];
        self.picker.view.hidden = YES;
        [self.picker.view removeFromSuperview];
    }

    - (void)imagePickerController:(UIImagePickerController *)currentPicker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
    {
        [self saveImage:image withImageName:@"myPhoto"];

    }

//saving an image

- (void)saveImage:(UIImage*)image withImageName:(NSString*)imageName {

NSData *imageData = UIImagePNGRepresentation(image); //convert image into .png format.

谢谢..:）Neet

**将uiimage从photolibrary保存到捆绑包**

（无效）imagePickerController:（UIImagePickerController*）PickerDidFinishPickingImage:（UIImage*）图像编辑信息：（NSDictionary*）编辑信息 {

嗨，克里斯蒂娜，你是否检查UIImage*图像是否为零？图像数据是否为零？我认为为零，这就是问题所在。我在从一个图像视图到另一个图像获取图像时非常困惑，你能告诉我对不起，你不能指定我代码中的更改吗？请…你是从图像视图获取图像吗？下面我的ans是save im照片库中的年龄。我也从照片库中提取我的图像并保存到应用程序包中，但没有任何用处。只需查看我的代码并告诉我必须在哪里进行更改，但它是用于照片而不是视频
