獲取錯誤，該方法未定義

我有一個鏈接到詳細子視圖的子視圖。見下文。這.H恰恰是在我目前使用兩個頭文件相同，除了@interface _（上一個和喬治·華盛頓約翰·亞當斯在其他。獲取錯誤，該方法未定義

@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，看一看兩個.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]; 

}

在約翰Adams.m，而不是裝載WebView3和WebView4，它加載WebView1和WebView2。此外，約翰Adams.m收到一個警告，方法定義爲兩個-wikiButtonPressed和bioButtonPressed未定義（但不在GeorgeWashington.m上）我做錯了？

因此，當JohnAdams生物按鈕被按下時，執行不會輸入JohnAdams.m中的代碼？如果是這種情況，則xib可能與錯誤的控制器相關聯。 –

您使用的是界面生成器嗎？（顯然，你這樣做，因爲您聲明IBOutlets）

如果是這樣，然後檢查JohnAdams.xib的文件所有者的類名。
