Iphone UIButton无法在嵌套的UIViews中工作 [英] Iphone UIButton not working in nested UIViews

问题描述

这真是太简单了！我错过了一些东西，我试图解决它已经筋疲力尽了。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Button可以正常工作但是在CharacterMale.m中嵌套的按钮却没有。我没有使用IB一切都是按步骤完成的。
什么会导致一个按钮工作而其他按钮不工作？

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

最后!!!!!!

我必须使用initWithFrame初始化所有视图并传入有效的帧rects。 Init应与控制器和initWithFrame一起使用，传递UIViews !!!!

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];
