我正在创建一个将继续在后台运行的应用程序。当设备连接到 MAC 并调试时，但当我断开连接并独立运行应用程序时，它将在 10 分钟内完成。是否有任何设置或我的编码错误？

我的代码是 appdeledate.h 是

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


@class TashouNoEnViewController;

@interface TashouNoEnAppDelegate : NSObject <UIApplicationDelegate,GKSessionDelegate,GKPeerPickerControllerDelegate> {
    UIWindow *window;
    TashouNoEnViewController *viewController;
    GKSession *mySession;
    IBOutlet UITextField *messageTextField;
    UIBackgroundTaskIdentifier backgroundTaskIdentifer;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet TashouNoEnViewController *viewController;

@property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
@end

appdelegate.M 是

#import "TashouNoEnAppDelegate.h"
#import "TashouNoEnViewController.h"
#define kSessionID @"_tashounoen"

@implementation TashouNoEnAppDelegate

请有人帮忙。

Apple 只允许应用程序的后台处理持续 10 分钟（过去只有 5 分钟），除非应用程序是音乐、VOIP 或导航，在这种情况下，您需要在 Plist 文件中指定。

这就是为什么您的应用程序在 10 分钟后停止的原因，默认情况下 Xcode 将在您调试时继续运行应用程序。
