Question

我有一个链接到详细子视图的子视图。见下文。这个.h在我目前使用的两个头文件中完全相同，除了@interface _ （一个是JohnAdams，另一个是GeorgeWashington。

@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

然而，看看两个.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John Adams.m中，它不是加载WebView3和WebView4，而是加载WebView1和WebView2。此外，John Adams.m收到一条警告，即-wikiButtonPressed和bioButtonPressed的方法定义未定义（但不在GeorgeWashington.m上）。我做错了什么？

Answer 1

您使用的是界面构建器吗？（显然你这样做是因为你宣布IBOutlets）

如果是，请检查JohnAdams.xib文件所有者的类名。
