我有一个使用Interface Builder构建的应用程序不，我需要添加一个新的弹出视图，让用户做出以下三种选择之一：攻击，防御或返回上一个屏幕。我以为我会尝试使用Interface Builder来创建视图，构建相关的方法，并轻松地将它们链接在一起，但我遗憾地错误。
我已经看到了这个网站上有关使用Interface Builder的所有抱怨，但是我希望我犯了一些简单的错误，因为他们自己找到了结果，所以没有人打扰报告。
这是Information Builder生成的视图的XML：

这是我为“AttackOrDefendViewController”类创建的头文件：
#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import <UIKit/UIKit.h>
@interface AttackOrDefendViewController : UIViewController
{
}
// the player has chosen to attack...
- ( IBAction ) btnAttack: ( id ) sender;
// the player has chosen to defend...
- ( IBAction ) btnDefend: ( id ) sender;
// go back to the previous screen...
- ( IBAction ) btnBack : ( id ) sender;
@end // end @interface AttackOrDefendViewController
这是该类的实现：
#import "AttackOrDefendViewController.h"
@implementation AttackOrDefendViewController
// additional setup while loading the view from the nib ("xib" file)...
- ( id ) initWithNibName: ( NSString * ) nibNameOrNil
bundle: ( NSBundle * ) nibBundleOrNil
{
// always call the parent method...
self = [ super initWithNibName: nibNameOrNil
bundle: nibBundleOrNil
];
// idiot check...
NSAssert( ( self )
, @"error allocating object"
);
return self;
} // end AttackOrDefendViewController::initWithNibName
// additional setup after loading the view from the nib ("xib" file)...
- ( void ) viewDidLoad
{
// always call the parent method...
[ super viewDidLoad ];
return;
} // end AttackOrDefendViewController::viewDidLoad
// clean-up method...
- ( void ) dealloc
{
// remember to call the parent "dealloc" method...
[ super dealloc ];
return;
} // end AttackOrDefendViewController::dealloc
// the player has chosen to attack...
- ( IBAction ) btnAttack: ( id ) sender
{
return;
} // end AttackOrDefendViewController::btnAttack
// the player has chosen to defend...
- ( IBAction ) btnDefend: ( id ) sender
{
return;
} // end AttackOrDefendViewController::btnDefend
// go back to the previous screen...
- ( IBAction ) btnBack : ( id ) sender
{
return;
} // end AttackOrDefendViewController::btnBack
@end // end @implementation AttackOrDefendViewController
我遇到的问题是，根据我在StackOverflow上阅读的所有内容，应该有一种简单的方法将视图中的对象拖动连接到适当的方法，但没有显示任何内容当我控制时 - 点击指示的单选按钮，特别是“触摸内部”按钮。我已经尝试将“文件所有者”选项链接到该类，但同样没有任何显示。
答案 0 :(得分：0)
我发现了这个问题。当您想在最初使用它构建的应用程序中使用Interface Builder时，XCode的表现并不好。我需要手动编辑＆＃34; xib＆＃34; file使用＆＃34; customClass＆＃34;提供视图对象和代码之间的链接。 ＆＃34;占位符＆＃34;中的字段标签
<placeholder placeholderIdentifier="IBFilesOwner" id="-1" userLabel="File's Owner" customClass="AttackOrDefendViewController">
在我这样做之后，我能够将相应的按钮与相应的方法相关联。
新的＆＃34; xib＆＃34;文件现在看起来像这样：
