如何使用图像SWIFT创建一个弹出窗口 [英] How to make a popup window with an image SWIFT

问题描述

我想知道如何创建一个类似于这个例子的弹出窗口：

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

原点窗口中有很多按钮，选中这些按钮后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

我只想创建一个可重复使用的 UIView 组件以及作为子视图所需的一切，例如作为您的图像的 UIImageView ， UILabel 或 UIButton 在右上角。以下是显示它的过程：

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 UIView ，它占用了全屏，让它变成黑色，也许是0.5 alpha。


2. 创建另一个 UIView 这是你的主要弹出视图，制作它稍微小于上一个视图，但请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，我甚至建议如果你计划使用它，可以创建一个 UIView 子类。


4. 要显示弹出窗口，请确保设置了两个视图在创建时 hidden = true ，以便在选择按钮时，可以将它们设置为 hidden = false


5. 如果你想要它们的动画，只需用 alpha = 0.0 启动它们并使用类似UIView的 animateWithDuration 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

有很多小事您可以更改以满足您的需求的详细信息，但这是如何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.
