我来自iOS开发背景。我在appdelegate中创建简单的mac应用程序我将NSViewController实例添加到窗口,并且我在NSViewController类中有一个按钮。当我点击按钮时,它崩溃。我看着这些帖子,但我无法弄清楚我的应用出了什么问题。 Why would my app not be able to "attach" an action?点击按钮时应用程序崩溃
这里是按钮
-(IBAction)startClicked:(id)sender{[email protected]"Btn selected";}
当我按一下按钮,应用程序崩溃的应用程序委托
PrViewController *pcVC = [[PrViewController alloc] initWithNibName:@"PrViewController" bundle:nil];
[self.window.contentView addSubview:pcVC.view];
函数的代码。 以下是堆栈跟踪:
