Question

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，会出现应该出现的全屏广告（我正在使用RevMob）。但是，当我退出广告时，我会看到一个黑色屏幕，顶部有一个蓝色状态栏。

我尝试了很多东西，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，我也不想删除广告，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];
 }

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（不）发生的事情是您的应用没有内容。我怀疑你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：

摆脱所有 ~~app~~ 广告代码，只需创建一个有效的应用。它所要做的就是正确显示初始视图控制器。您可以使用单视图应用程序模板在XCode中创建一个新项目。
按this example添加您的应用代码。您将通过按钮从初始视图控制器调用代码。
一旦有效，您可以根据您的问题将代码添加到- (void)applicationDidBecomeActive:(UIApplication *)application。当您关闭广告时，您应该看到您的初始视图控制器。
