Iphone UIButton不能正常工作

这真是太简单了！我错过了一些东西，并试图修复它，我筋疲力尽。希望有人可以提供帮助。Iphone UIButton不能正常工作

CharacterView.m中的Button工作，但在CharacterMale.m中嵌套的按钮没有。我没有使用IB，所有事情都是按照步骤完成的。

CharacterView.m被用作容器

您是否将按钮事件设置为NIB文件中的第一响应者？ – balexandre 2009-05-04 18:34:01

NIB文件？我不使用IBuilder。对？ – 2009-05-04 18:46:39

您CharacterController在loadView中泄漏characterView – nduplessis 2009-05-04 18:55:06

FINALLY !!!!!!

我不得不用initWithFrame初始化所有视图并传入有效的帧rects。初始化应该与控制器一起使用，并且initWithFrame为UIViews传递rects！

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