Question

问题看起来像是以popover事件为中心。防爆。我点击相机..它以模态方式启动相机直到屏幕的绝对顶部..如果我点击取消并重复...一切看起来都很完美。现在，如果我选择查看popover相机Roll ..下次启动相机时，它也会从屏幕顶部大约20px，按钮导航栏只有一半可见。（请记住，标准屏幕具有标准顶部栏，但模态摄像机占据了完整的绝对屏幕1024x768）。

我的代码：

- (IBAction) getPhoto: (id)sender
{
    if ([self.popoverController isPopoverVisible]) {
        [self.popoverController dismissPopoverAnimated:YES];
    }

    else if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    {

        imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
        imagePicker.allowsEditing = YES;
        [self presentModalViewController:imagePicker animated:YES];    
    }
}

- (IBAction) useCameraRoll: (id)sender
{
    if ([self.popoverController isPopoverVisible]) {
        [self.popoverController dismissPopoverAnimated:YES];

    } 
    else if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum])
    {
        imagePicker.sourceType =UIImagePickerControllerSourceTypePhotoLibrary;
        self.popoverController = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
        popoverController.delegate = self;
        [self.popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
    }

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [picker dismissModalViewControllerAnimated:YES];
}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
{
    [self.popoverController dismissPopoverAnimated:true];
    UIImage *savedimage = [editingInfo objectForKey:UIImagePickerControllerOriginalImage];
    imageView.image = savedimage;
    UIImageWriteToSavedPhotosAlbum (savedimage, self, nil, nil);
}

我相信当您在弹出窗口中显示UIImagePickerController时，弹出窗口会保留视图并导致一些问题。试图通过破坏popover（及其子视图）或将popover内容设置为nil来从popover释放视图。防爆。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage (UIImage *)image editingInfo:(NSDictionary *)editingInfo
{
    [self.popoverController setContentViewController:nil]; 
    [self.popoverController dismissPopoverAnimated:true];
    UIImage *savedimage = [editingInfo objectForKey:UIImagePickerControllerOriginalImage];
    imageView.image = savedimage;
    UIImageWriteToSavedPhotosAlbum (savedimage, self, nil, nil);
}
