XCode:以编程方式添加多个具有特定名称和动画的按钮 [英] XCode: Add multiple buttons programmatically with specific names and animate

问题描述

我刚刚阅读了这篇关于 以编程方式添加带有循环的按钮.

I just read this post about adding buttons with a loop programmatically.

我想做同样的事情，但要为每个人指定一个名称，并以相同的方式为其制作动画.这是一个好主意，还是我应该为每个按钮复制同一行代码?

I want to do the same thing, but do it with a name for each one, and animate them the same way. Is this a good idea, or should I just copy the same line of code for each button?

此外，我想从名称列表(大于四个)中添加多个按钮(比如四个)并随机选择它们.问题是，我需要正确命名它们并提取与每个名称相关联的图像.有什么想法吗?

Further, I'd like to add a number of buttons (say four) from a list of names (greater than four) and pick them randomly. The catch is, I need them to be named properly and pull images associated with each name. Any ideas?

推荐答案

如我所见，您应该使用按钮信息数组创建一个属性列表 (.plist) - 对于每个按钮都会显示文本，图片显示和操作(方法名称或其他东西).您可以在 [0, [buttonArray length]] 范围内生成四个不同的随机数，然后在循环中为每个选定的数字生成按钮.

As I see it, you should make a property list (.plist) with the array of buttons info - for each button there will be text to display, pic to display and action (method name or something). You can generate four different random numbers in range [0, [buttonArray length]] and then generate your buttons in the loop for each selected number.

我想，你需要类似 buttonFactory 的方法

I guess, you need something like buttonFactory with method

-(UIButton*) makeButtonWithInfo(NSDictionary*)info

名称、图片地址、动作等存储在 info 中的位置(如果它很复杂，您可以自定义类型 buttonInfo).

where name, picture adress, action etc. stored in info (you custom type buttonInfo if it is complicated).

更新:

在 Xcode (resources/PropertyList) 中创建新的 .plist 并像这样填充它:

Create new .plist in Xcode (resources/PropertyList) and fill it like this:

在您的代码中阅读它

NSArray* buttonsArray = [NSArray arrayWithContentsOfFile:myPlist.plist];

此数组中将包含带有按钮信息的字典.

There will be dictionaries with button info in this array.
