ios开发eaaccessory案例_ios – EAAccessoryManager connectedAccessories返回空数组

你能试试这个功能吗？

- (void)_getAttachedDevices;

{

EAAccessoryManager* accessoryManager = [EAAccessoryManager sharedAccessoryManager];

if (accessoryManager)

{

NSArray* connectedAccessories = [accessoryManager connectedAccessories];

NSLog(@"ConnectedAccessories = %@",connectedAccessories);

}

else

{

NSLog(@"No accessoryManager");

}

}

你得到了哪些结果？

显然记得EAAccessory仅适用于Made-For-iPod / iPhone / iPad / AirPlay许可配件;因此,如果您没有许可配件,您将始终看到一个空数组.您是否拥有正规的MFI附件？

如果您仍然卡住,请尝试实施connect / disconnect通知：

[[EAAccessoryManager sharedAccessoryManager] registerForLocalNotifications];

[[NSNotificationCenter defaultCenter] addObserver:self

selector:@selector(accessoryDidConnect:)

name:EAAccessoryDidConnectNotification

object:nil];

[[NSNotificationCenter defaultCenter] addObserver:self

selector:@selector(accessoryDidDisconnect:)

name:EAAccessoryDidDisconnectNotification

object:nil];

您是否看到了设备的连接？如果是,请尝试获取已连接设备的列表
