我的问题是如何实现此代码(我将把它放在buttonPress方法中)
我需要在头文件中定义任何内容吗？令我困惑的是,apple on提供了这个并且没有头文件,所以我不知道是否应该有什么？
代码引用了RecipieAddViewController,我还能用“UIViewController”来解决这个问题？
我在头文件中作为委托放了什么？我需要在其他地方设置吗？喜欢财产？
一旦我在buttonPress方法中复制此代码以使其工作,我还需要做些什么吗？
感谢并抱歉所有问题.
解决方法
My question is how do I implement this code (I’m going to place it in a buttonPress method)
将方法定义为IBAction,如 – (IBAction)add：(id)sender并在界面构建器中将按钮的内部事件绑定到视图控制器对象的add：action outlet.
Do I need to define anything in my header file? The bit that confuses me is that apple on provides this and no header file so i cant tell if anything should be there?
不.所有这些东西需要的是UIKit.h您通常需要更改标头以添加方法,添加实例变量或包含自定义类.但是,您可能需要在某处(在标题或实现文件中)使用#import RecipeAddViewController.h才能使用该类.对于要在另一个文件中使用的任何自定义类,都是如此.
The code refers to RecipieAddViewController what do I repleace this with,“UIViewController”?
将其替换为要推送的视图控制器类. UIViewController本身很少有用.它是为子类化的.因此,您创建一个继承自UIViewController的新类,导入它的标题,创建它的实例,并将其推送到导航控制器上.
