未找到不完整的实现和方法定义“..”

Question

我是Xcode的初学者，我遇到了问题。 当我在iOS模拟器中启动我的应用程序时，应用程序启动然后失败。 它告诉我，我有一个不完整的实现。它说没有找到“页面”的方法定义。

AppDelegate.h

#import <UIKit/UIKit.h>
 #import <MapKit/MapKit.h>




@class ViewController;

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;

@property(nonatomic, retain) MKMapView *mapView;

-(IBAction)page:(id)sender;

@end

ViewController.h

#import <UIKit/UIKit.h>
#import "MapKit/MapKit.h"



  @interface ViewController : UIViewController {



 IBOutlet MKMapView *mapView;
     IBOutlet UISegmentedControl *maptype;

}


- (IBAction)locate:(id)sender;
- (IBAction)page:(id)sender;

@end

---

AppDelegate.m

#import "AppDelegate.h"

#import "ViewController.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary     *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[ViewController alloc] initWithNibName:@"ViewController"      bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}

有人可以帮忙吗？ 非常感谢！

检查您是否错过了在ViewController.m file中定义方法的方法。

-(IBAction)page:(id)sender  
{   
// your code here  
}
