我是 Objective-C 的新手，我正在制作我的第一个应用程序，一个单视图应用程序。当我运行我的程序时，应该出现的全屏广告（我正在使用 RevMob）出现。但是，当我退出广告时，我会看到一个黑屏，顶部有一个蓝色状态栏。

我尝试了很多事情，例如将我的主视图控制器设置为初始视图控制器、重新启动计算机、更改/删除调试器、重置 iOS 模拟器等。

我的 Xcode 版本是 4.6，我的操作系统是 mac OSX 10.8.4

我不想删除 Xcode，也不想删除广告，因为这是我唯一的收入来源。

这是我的代码：

Appdelegate.m

@implementation AppDelegate



 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:     (NSDictionary *)launchOptions
  {

[RevMobAds startSessionWithAppID:@"myappid"];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

 [self.window makeKeyAndVisible];
return YES;
  }


  - (void)applicationWillResignActive:(UIApplication *)application
  {
// Sent when the application is about to move from active to inactive state. This can     occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the   background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES      frame rates. Games should use this method to pause the game.
 }

- (void)applicationDidEnterBackground:(UIApplication *)application
{
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}


 - (void)applicationDidBecomeActive:(UIApplication *)application
{
 // Restart any tasks that were paused (or not yet started) while the application was    inactive. If the application was previously in the background, optionally refresh the user    interface.
RevMobFullscreen *ad = [[RevMobAds session] fullscreen];
[ad loadWithSuccessHandler:^(RevMobFullscreen *fs) {
    [fs showAd];
    NSLog(@"Ad loaded");
} andLoadFailHandler:^(RevMobFullscreen *fs, NSError *error) {
    NSLog(@"Ad error: %@",error);
} onClickHandler:^{
    NSLog(@"Ad clicked");
} onCloseHandler:^{
    NSLog(@"Ad closed");
}];
}


 - (void)applicationWillTerminate:(UIApplication *)application
{
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

- (void)dealloc
 {
[_window release];
[super dealloc];
 }

@end

Appdelegate.h:

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


@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic)UIWindow *window;


@end

广告代码没有任何问题。似乎（没有）发生的是您的应用程序没有内容。我怀疑您没有正确设置应用程序的 rootViewController（初始视图控制器）。

这是你需要做的：

  1. 摆脱所有的应用程序广告代码，只需制作一个有效的应用程序。它所要做的就是正确显示一个初始视图控制器。您可以使用 Single View Application 模板在 XCode 中创建一个新项目。

  2. 根据此示例添加您的应用程序代码。您将通过按钮从初始视图控制器调用代码。

  3. 一旦工作正常，您可以- (void)applicationDidBecomeActive:(UIApplication *)application根据您的问题将代码添加到其中。当您关闭广告时，您应该会看到您的初始视图控制器。
