获取错误，该方法未定义

问题描述：

我有一个链接到详细子视图的子视图。见下文。这.H恰恰是在我目前使用两个头文件相同，除了@interface _（上一个和乔治·华盛顿约翰·亚当斯在其他。获取错误，该方法未定义

@interface JohnAdams : UIViewController { 

NSString *selectedCountry; 
IBOutlet UIButton *bio; 
IBOutlet UIButton *wiki; 
} 
@property (nonatomic, retain) NSString *selectedCountry; 
@property (nonatomic, retain) UIButton *wiki; 
@property (nonatomic, retain) UIButton *bio; 

-(IBAction)wikiButtonPressed:(id)sender; 
-(IBAction)bioButtonPressed:(id)sender; 
@end

但是，看一看两个.M的

//George Washington.m 
-(IBAction)wikibuttonPressed:(id)sender { 
WebView1 *detailvc = [[WebView1 alloc] initWithNibName:@"WebView1" bundle:nil]; 
[detailvc setTitle:@"Wikipedia"]; 
[self.navigationController pushViewController:detailvc animated:YES]; 
[detailvc release]; 

} 

-(IBAction)biobuttonPressed:(id)sender { 
WebView2 *detailvc2 = [[WebView2 alloc] initWithNibName:@"WebView2" bundle:nil]; 
[detailvc2 setTitle:@"The White House"]; 
[self.navigationController pushViewController:detailvc2 animated:YES]; 
[detailvc2 release]; 
} 

//JohnAdams.m 
-(IBAction)biobuttonPressed:(id)sender { 
WebView4 *detailvc4 = [[WebView4 alloc] initWithNibName:@"WebView4" bundle:nil]; 
[detailvc4 setTitle:@"The White House"]; 
[self.navigationController pushViewController:detailvc4 animated:YES]; 
[detailvc4 release]; 
} 


-(IBAction)wikibuttonPressed:(id)sender { 
WebView3 *detailvc3 = [[WebView3 alloc] initWithNibName:@"WebView3" bundle:nil]; 
[detailvc3 setTitle:@"Wikipedia"]; 
[self.navigationController pushViewController:detailvc3 animated:YES]; 
[detailvc3 release]; 

}

在约翰Adams.m，而不是装载WebView3和WebView4，它加载WebView1和WebView2。此外，约翰Adams.m收到一个警告，方法定义为两个-wikiButtonPressed和bioButtonPressed未定义（但不在GeorgeWashington.m上）我做错了？

因此，当JohnAdams生物按钮被按下时，执行不会输入JohnAdams.m中的代码？如果是这种情况，则xib可能与错误的控制器相关联。 –

答

您使用的是界面生成器吗？（显然，你这样做，因为您声明IBOutlets）

如果是这样，然后检查JohnAdams.xib的文件所有者的类名。
