如何创建自定义UIAlertView [英] How to create custom UIAlertView
问题描述
我们正在创建一个身临其境的应用程序，需要具有与 UIAlertView 类似的东西，但我们不希望它看起来像一个系统对话框，我们想使用我们自己的图形。我有一大块的工作，但有一些阻碍我击中：
We're creating an immersive app that needs to have something that acts rather similar to a UIAlertView, but we don't want it to look like a system dialog, we want to use our own graphics. I've got a big chunk of the work done, but there are a few snags I've hit:
-
如何做我使UIView显示在状态栏上方（这样我可以变暗，像
UIAlertView）？这可能吗？
如何显示它部分透明，但文字仍然完全显示在窗口中，但它仍然显示在状态栏下面。不透明？我想让它显示类似于 UIAlertView ，它应该是半透明的，但如果我设置alpha为.8，这也减少了子视图的alpha。如果我只减少背景图像的alpha，那么按钮看起来不透明。如果我减少背景图像和按钮的alpha，那么按钮看起来不像它们嵌入在背景图像中。我非常希望不必为每个嵌入按钮的排列创建不同的图片
How do I show it partially transparent but have the text still fully opaque? I want it to be shown similar to a UIAlertView in that it should be translucent, but if I set alpha to .8, that also decreases the alpha of subviews. If I only decrease the alpha of the background image, then the buttons appear opaque. If I decrease the alpha of the background image and the buttons, then the buttons don't look like they are embedded in the background image. I would very much like to not have to create a different image for each arrangement of embedded buttons
：我还没有找到解决状态栏问题，但我注意到，一个标准的UIAlertView显示在自己的UIWindow，当我调查，我发现了windowLevel属性：
I haven't yet found a solution to the status bar issue, but I've noticed that a standard UIAlertView shows up in its own UIWindow, and when I investigated that, I found the windowLevel property:
const UIWindowLevel UIWindowLevelNormal;
const UIWindowLevel UIWindowLevelAlert;
const UIWindowLevel UIWindowLevelStatusBar;
使用自己的UIWindow与 UIWindowLevelAlert 不要使其显示在状态栏上方。我没有尝试 UIWindowLevelStatusBar 。
Using my own UIWindow with UIWindowLevelAlert still didn't make it show up above the status bar. I didn't try UIWindowLevelStatusBar.

我不认为苹果使用这个非 - UIAlertView UIView 的子类。
I don't think Apple makes this available to a non-UIAlertView subclass of UIView.
UIAlertView UIView 。您是否尝试用自己的绘图代码子类化 UIAlertView 并覆盖 -drawRect：？
UIAlertView is a subclass of UIView. Have you tried subclassing UIAlertView and overriding -drawRect: with your own drawing code?
