Change Background Color of iOS App When Pushing Views
提问by user717452
In my app, I use a navigation controller to switch between different views. Each of my views has an image for a background, but when I go from one to another, a little bit of white shows up in between them while transitioning. Is there a way to change that?
在我的应用程序中，我使用导航控制器在不同视图之间切换。我的每个视图都有一个背景图像，但是当我从一个视图转到另一个视图时，在过渡时它们之间会出现一点白色。有没有办法改变它？
In the Table View Class I have this in the viewDidLoad:
在表视图类中，我在 viewDidLoad 中有这个：
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"parchment.png"]];
self.tableView.backgroundColor = [UIColor clearColor];
self.tableView.backgroundView = imageView;
[imageView release];
In the detail view I have just a standard loadrequest for an HTML. The HTML itself has the code for the parchment paper to be a background image. Here is what they look like:
在详细视图中，我只有一个标准的 HTML 加载请求。HTML 本身具有将羊皮纸作为背景图像的代码。这是它们的样子：
But, going back from the detail view with the verses to the table view, I get this:
但是，从带有经文的详细视图返回到表视图，我得到了这个：

The issue was in the viewWillDisappear of the web view controller. It was set to change webpage to about:blank page, which made it white. I got rid of that code, and it worked fine.
问题出在 web 视图控制器的 viewWillDisappear 中。它被设置为将网页更改为 about:blank 页面，使其变为白色。我摆脱了那个代码，它工作得很好。

Try to set the background color of the navigation controller's view.
尝试设置导航控制器视图的背景颜色。
In your navigation controller's root view controller (I guess it's the table view controller)
在您的导航控制器的根视图控制器中（我猜它是表视图控制器）
self.navigationController.view.backgroundColor = // any color ;
