HomkeKit开发：“输入设置代码”页面仅出现半秒，跳转到页面“无法添加DeviceName，主页无法连接到此附件”

Question

我正在学习开发HomeKit应用程序。我想给家里/房间添加一个附件。当我运行这个项目时，它能够发现附件，但不能将它添加到一个家庭或分配一个房间给附件。

根据本教程，该项目发现附件如下：

​

当我将附件添加到家庭/房间时，“输入设置代码”只显示半秒钟的，然后转向“无法添加XXX，Home无法中间连接该附件”，如下所示：

​

​

​

我用来为房间/家庭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

                    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函数试图捕获这两个错误，而error.localizedDescription只显示Failed to add the accessory

为什么我不能连接到附件？我哪里做错了？谢谢！！

Answer 1

由我自行修订

我在这里犯了个错误。在函数- (void)viewWillDisappear:(BOOL)animated中

我不应该包括[self.browser stopSearchingForNewAccessories]，否则如果我离开currentRoom页面，所有的发现过程都会停止。所以正确的版本是

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

愚蠢的我，但同时也是天才

Answer 2

在iPhone模拟器上，转到Settings->Privacy->HomeKit并选择“重置HomeKit配置”。

如果这不起作用，请删除Xcode并从App重新安装它。
