我來自iOS開發背景。我在appdelegate中創建簡單的mac應用程序我將NSViewController實例添加到窗口,並且我在NSViewController類中有一個按鈕。當我點擊按鈕時,它崩潰。我看着這些帖子,但我無法弄清楚我的應用出了什麼問題。 Why would my app not be able to "attach" an action?點擊按鈕時應用程序崩潰
這裏是按鈕
-(IBAction)startClicked:(id)sender{[email protected]"Btn selected";}
當我按一下按鈕,應用程序崩潰的應用程序委託
PrViewController *pcVC = [[PrViewController alloc] initWithNibName:@"PrViewController" bundle:nil];
[self.window.contentView addSubview:pcVC.view];
函數的代碼。 以下是堆棧跟蹤:
