当我的应用程序启动时,用户在我的应用程序启动时看到的第一个屏幕(视图)是没有任何导航的搜索表单。搜索过程完成后,导航将显示,并且结果已准备好显示。我坚持的地方是让它与导航控制器一起工作的正确方法。
因此,假设应用名称为RealEsateProperties
在RealEsatePropertiesAppDelegate.h中:
#import <UIKit/UIKit.h>
@class RealEsatePropertiesViewController;
@interface RealEsatePropertiesAppDelegate : NSObject <UIApplicationDelegate>
{
UINavigationController *ListingNav;
}
@property (nonatomic, retain) IBOutlet UIWindow window;
@property (nonatomic, retain) RealEsatePropertiesViewController *viewController;
// Then I added this line for the navigation
@property (nonatomic, retain) UINavigationController *ListingNav;
@end
并在RealEsatePropertiesAppDelegate.m中:
#import "RealEsatePropertiesAppDelegate.h"
#import "RealEsatePropertiesViewController.h"
@synthesize window=_window;
@synthesize window=_viewController;
@synthesize ListingNav;
@implementation RealEsatePropertiesAppDelegate
- (BOOL)application:(UIApplication *)application didFinishLanchingWithOptions:(NSDictionary *)launchOptions
{
self.window.rootViewController = self.viewController;
// Iadded the following 4 lines to try making the navigation thing work without showing any navigation bar on the first screen (that is the search form)
self.ListingNav = [[UINavigationController alloc] initWithRootController:self.viewController];
self.ListingNav.navigationBarHidden = YES;
[self.window addSubView:ListingNav.view];
[self.window makeKeyAndVisible];
return YES;
}
@end
我做错了吗?
求助,

您需要创建/分配您的RealEsatePropertiesViewController吗?
viewController = [[RealEsatePropertiesViewController alloc] init];
