如何使用 SWIFT 图像制作弹出窗口 [英] How to make a popup window with an image SWIFT

问题描述

我想知道如何制作类似于此示例的弹出窗口:

I was wondering how to make a popup window similar to this example:

原始窗口充满了按钮，当被选中时会拉出我想要使用的图像.

The origin window is full of buttons that when is selected will then pull up the image I desire to use.

推荐答案

我会简单地创建一个可重用的 UIView 组件以及作为子视图所需的一切，例如 UIImageView 对于您的图像，右上角的 UILabel 或 UIButton.这是展示它的过程:

I would simply create a reusable UIView component and everything you need as a subview, such as a UIImageView for your image, a UILabel or a UIButton in the top right. Here is the process to show it:

1. 创建一个占满全屏的 UIView，使其变黑，并且可能是 0.5 alpha.
2. 创建另一个 UIView 作为您的主要弹出视图，使其比前一个视图略小，但确保这两个视图都是父子视图的子视图.
3. 将所需元素作为子视图添加到弹出视图中，如果您打算经常使用它，我什至建议创建一个 UIView 子类.
要显示弹出窗口，请确保将两个视图设置为 hidden = true 创建时，以便选择按钮时，可以将它们设置为 hidden = false
4. 如果您希望它们具有动画效果，只需使用 alpha = 0.0 启动它们，然后使用 UIView 的 animateWithDuration 之类的东西，并将弹出视图设置为 alpha = 1.0

1. Create a UIView that takes up the full screen, make it black, and maybe 0.5 alpha.
2. Create another UIView which is your primary pop-up view, make it slightly smaller than the previous view, but make sure both of these views are subviews of the parent subview.
3. Add the desired elements on to the pop-up view as subviews, I would even suggest creating a UIView subclass if you plan to use this a lot.
4. To present the pop-up, make sure both views are set to hidden = true when created and so that when a button is selected, you can set them to hidden = false
5. If you would like them to be animated, simply start them off with alpha = 0.0 and use something like UIView's animateWithDuration and set the pop-up view to alpha = 1.0

您可以更改很多小细节以满足您的需求，但这是实现目标的基本结构.

There is a lot of little details you can change to cater to your needs, but this is the basic structure on how to accomplish your goal.
