HomkeKit开发者："Enter setup code"页面只出现半秒就跳转到页面"Couldn't add DeviceName, Home couldn't connect to this accessory"

Question

我正在学习开发 HomeKit 应用程序。我正在尝试向 home/room 添加附件。当我运行项目时，它能够发现配件，但无法将其添加到家庭或为配件分配房间。

根据教程，项目发现配件如下：

当我给home/room添加配件时，"Enter setup code" 只出现了半秒，然后中间变成了"Couldn't add XXX, Home couldn't connect this accessory" ，如下图：

我用来给 room/home 添加附件的部分代码如下所示：

currentRoomVC.h

#import <UIKit/UIKit.h>
#import "MyHomeKit.h"
@interface currentRoomVC : UIViewController<UIScrollViewDelegate,UITableViewDelegate,UITableViewDataSource,HMAccessoryBrowserDelegate>
@property (nonatomic,strong)HMRoom *currentRoom;
@property (nonatomic,strong)HMRoom *currentHome;

@property(nonatomic,strong) NSMutableArray *accArry;
@property(weak,nonatomic) IBOutlet UIScrollView *scroView;
@property(strong,nonatomic) IBOutlet UITableView *accTable;

@property(nonatomic,strong) HMAccessoryBrowser *browser;
@end

currentRoomVC.m

#import "currentRoomVC.h"

@interface currentRoomVC ()

@end

@implementation currentRoomVC

    [super viewWillAppear:YES];
    self.navigationController.navigationBar.hidden = NO;

    self.navigationController.navigationBar.hidden = YES;
    [self.browser stopSearchingForNewAccessories];
}

    [super viewDidLoad];
    self.view.backgroundColor = [UIColor yellowColor];
    self.navigationItem.title = self.currentRoom.name;

    self.accArry = [[NSMutableArray alloc] init];
    self.browser = [[HMAccessoryBrowser alloc]init];
    self.browser.delegate = self;

    [self configSearchBtn];
    [self cofigureTableview];

    HMAccessory *acc = _accArry[indexPath.row];

    __block HMRoom *room = self.currentRoom;



    [home addAccessory:acc completionHandler:^(NSError * _Nullable error) {

                // 3. If successfully, add the accessory to the room
                [home assignAccessory:acc toRoom:room completionHandler:^(NSError * _Nullable error) {
                    if (error) {
                        // Failed to add accessory to room
                        NSLog(@"Fail to assign room to room");
                    }
                    else{
                        NSLog(@"Add this device to %@", room.name);
                    }
                }];
            }
        }
    } ];


}

如您所见，didSelectRowAtIndexPath 函数尝试捕获这两个错误，而 error.localizedDescription 仅显示 Failed to add the accessory

为什么我无法连接到配件？我哪里做错了？谢谢！！

Answer 1

在 iPhone 模拟器上，转到设置->隐私->HomeKit 和 select "Reset HomeKit Configuration"。

如果这不起作用，请删除 Xcode 并从 App Store 重新安装。

Answer 2

自己修复了!!!!!!!!!!!!

我在这里犯了一个错误。在功能上 - (void)viewWillDisappear:(BOOL)animated

我不应该包含 [self.browser stopSearchingForNewAccessories] ，否则如果我离开 currentRoom 页面，所有发现过程都将停止。所以正确的版本是

- (void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:YES];
    self.navigationController.navigationBar.hidden = YES;
}

愚蠢的我也是天才!!!!! :)
