Put
shot.enabled=否
进入
-()viewDidLoad
函数。现在,在按下按钮之前,您不会告诉按钮被禁用


此外,您应该养成在objective-c中变量和函数名称中不大写第一个单词的第一个字母的习惯,例如,您可以命名字符串
myString
或按下的函数
-(void)按钮。您通常只将类名的第一个单词大写,例如
MyCustomObject

动画正在发生吗?什么叫“它不工作”?在这个短语中没有任何信息。我把shot.enabled=no;确实加载到视图中,但现在我无法在shot方法中使用if语句覆盖它。。谢谢你的帮助!我假设你有你的射击方法链接到你的射击按钮?如果是这种情况,您将无法从该方法重新启用它。可能添加
shot.enabled=YES到一个就绪方法的末尾,以便在应用程序通过这些方法后启用该按钮。
