HomkeKit开发：“输入设置代码”页仅半秒，并跳转到页面“不能添加设备名称，首页无法连接到该附件”

Question

我学习开发HomeKit应用。我正在尝试为家中/房间添加配件。当我运行该项目时，它能够发现附件，但无法将其添加到家中或为附件分配空间。

按照教程，该项目发现如下的配件：

当我将附件添加到主/间，“输入设置代码” 仅出现半秒，然后将其变为“不能添加XXX，首页无法连接此附件” intermediatly，如下图所示：

我所使用的部分代码添加附件室/家庭如下所示：

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

    NSLog(@"current home: %@", self.currentHome.name); 

    HMAccessory *acc = _accArry[indexPath.row]; 
    __block HMHome *home = self.currentHome; 
    __block HMRoom *room = self.currentRoom; 



    [home addAccessory:acc completionHandler:^(NSError * _Nullable error) { 
     if (error) 
     { 
      // Failed to add accessory to home 
      NSLog(@"Fail to add device to home %@",error.localizedDescription); 
     } 
     else 
     { 
      if (acc.room != room) { 
       // 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); 
        } 
       }]; 
      } 
     } 
    } ]; 


} 

正如你可以看到didSelectRowAtIndexPath函数试图抓住这两个错误和error.localizedDescription只能说明Failed to add the accessory

为什么我不能连接到配件？我哪里错了？谢谢！！

Answer 1

由我自己定!!!!!!!!!!!

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

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

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

愚蠢的我，但也天才!!!!! :)

Answer 2

在iPhone模拟器，进入设置 - >与隐私> HomeKit并选择“重置HomeKit配置”。

如果还是不行，请删除Xcode和从App Store重新安装。
