.h文件中

@class AppDelegate; 

@interface BarButton : UIView 
{ 

     AppDelegate *appDelegate; 

} 

@property(retain,nonatomic)AppDelegate *appDelegaet;

    OrderViewController *orderView=[[OrderViewController alloc] 
     initWithNibName:@"OrderViewController" bundle:nil]; 
    [appDelegate.navObj.navigationController pushViewController:orderView animated:YES]; 

} 

Answer 1

請更新您此行代碼

[appDelegate.navObj.navigationController pushViewController:orderView animated:YES]; 

到

[appDelegate.navObj pushViewController:orderView animated:YES];
