AR窗口与Window切换处理

Posted on

最近做的一个项目需要AR模块，具体功能就是用户到一个地方后，拿起手机切换到AR窗口会有活动图标。点击图标然后跳转到新的页面。比如图片浏览，视频播放，领取红包功能。当然今天不会写这些的具体的功能及如何整合。主要还是说下窗口来回切换的问题及处理方法。

其实当应用启动时 ,AR的窗口已经在运行了。其实就是切换window的rootView。

入口类处理

AppDelegate.h

@property (strong, nonatomic) UIWindow *unityWindow;
@property (strong, nonatomic) UnityAppController *unityController;

-(UIWindow *)unityWindow{
    
    return  UnityGetMainWindow();
}

-(void)showUnityWindow{
    
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
    self.unityWindow.hidden = NO;

    [self.unityWindow makeKeyAndVisible];
}

-(void)hideUnityWindow{
    
    [[UIApplication sharedApplication] setStatusBarHidden:NO];
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
    self.unityWindow.hidden = YES;
    [self.window makeKeyAndVisible];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//添加如下代码
    BOOL returnBool;
    if (_unityController == nil) {
        
        _unityController = [[UnityAppController alloc] init];
    }
    
    returnBool = [_unityController application:application didFinishLaunchingWithOptions:launchOptions];

}

创建一个单利类，管理切换标识控制

@interface SendInfoARManager : NSObject
/** 是否暂停Unity */
@property (assign, nonatomic) BOOL unityIsPaused;
@property (strong,nonatomic) NSTimer *timer;
+ (instancetype)sharedInstance;
@end

@implementation SendInfoARManager

+ (instancetype)sharedInstance
{
    static LARManager *manager;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        manager = [[self alloc] init];
    });
    return manager;
}

- (instancetype)init
{
    if (self = [super init]) {
        self.unityIsPaused = NO;
        NSLog(@"单例初始化成功");
    }
    return self;
}


@end

UnityAppController.h

我把整个代码都贴下，怎么修改对照比对下就行了
