Iphone UIButton 在嵌套的 UIViews 中不起作用 [英] Iphone UIButton not working in nested UIViews

问题描述

我敢肯定，这该死的简单！我错过了一些东西，并且因为试图修复它而筋疲力尽.希望有人可以提供帮助.

This is so damn simple im sure! Im missing something and im exhausted from trying to fix it. hopefully someone can help.

CharacterView.m 中的按钮有效，但嵌套在 CharacterMale.m 中的按钮无效.我没有使用 IB，一切都是以编程方式完成的.什么会导致一个按钮工作而另一个按钮不工作?

The Button in CharacterView.m works but the button nested down in CharacterMale.m does not. I'm not using IB everything is done progmatically. What would cause one button to work and other not?

推荐答案

终于！！！！！！

我必须使用 initWithFrame 初始化所有视图并传入有效的框架矩形.Init 应该与控制器一起使用，并且 initWithFrame 为 UIViews 传递矩形！！！！

I had to init all the views with initWithFrame and pass in valid frame rects. Init should be used with controllers and initWithFrame passing rects for UIViews!!!!

characterView = [ [ CharacterView alloc ] initWithFrame:CGRectMake(0, 0, 480, 320)]; 
then 
characterMale = [ [ CharacterMale alloc ] initWithFrame:frame];
