使用倍数信标(在每个不同的信标上弹出视图)

Question

我在目标C初学者.我的应用程序与一个灯塔正常工作.我正在使用"estimote SDK".我有很多问题,我想使用2或3个信标.我想为每个信标推送一个View.

我不明白我怎么能用多个信标做到这一点.

1. 我不知道是否必须使用多个信标管理器.(ESTBeaconManager*beaconManager)

2. 我不知道如何将不同区域传递给didRangeBeacons :( NSArray*)beacons inRegion:(ESTBeaconRegion*)region

3. 我可以使用一个信标仅用于通知,而另外两个用于在我们关闭时弹出2个不同视图.(每个信标的一个不同视图)

谢谢你的帮助.

最好的祝福.

好的,我工作了我的代码,现在我用一个区域做.我的信标阵列有3个信标.

region = [[ESTBeaconRegion alloc] initWithProximityUUID:ESTIMOTE_PROXIMITY_UUID identifier:@"multibeacons"];

我不会在初始化时使用主要或次要.

在ViewDidAppears我做:

[self.beaconManager startRangingBeaconsInRegion:region];

代表是这样的:

-(void)beaconManager:(ESTBeaconManager *)manager
     didRangeBeacons:(NSArray *)beacons
            inRegion:(ESTBeaconRegion *)region
{

// I used a sort , sorting by distance
    NSSortDescriptor *sortDescriptor;
    sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"distance" ascending:YES];
    NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor];

// if breakpoint here 3 beacons in array
    self.beaconsArray = [beacons sortedArrayUsingDescriptors:sortDescriptors];

    if([self.beaconsArray count] > 0)
    {

        if(!self.selectedBeacon)
        {
            // initialy pick closest beacon
            self.selectedBeacon = [beacons objectAtIndex:0];
            currentBeaconMinor = self.selectedBeacon.minor;
        }
        else
        {
            for (ESTBeacon* cBeacon in self.beaconsArray)
            {
                // update beacon it same as selected initially
                if([self.selectedBeacon.major unsignedShortValue] == [cBeacon.major unsignedShortValue] &&
                   [self.selectedBeacon.minor unsignedShortValue] == [cBeacon.minor unsignedShortValue])
                {
                    self.selectedBeacon = cBeacon;
                    currentBeaconMinor = self.selectedBeacon.minor;
                }
            }
        }

我按距离排序,我有一个currentBeaconMinor值.我的灯塔阵列里面有3个信标,如果我放置断点,我可以看到3.

在Switch proximity中,我这样做:

switch (self.selectedBeacon.proximity)
        {

            case CLProximityImmediate:
            {

                if ([currentBeaconMinor floatValue] == 128)
                {
                    NSLog(@"128 128 128");
                    //[self performSegueWithIdentifier: @"presentSegue1" sender: self];
                }

                else if ([currentBeaconMinor floatValue] == 228)
                {
                    NSLog(@"228 228 228");
                    //[self performSegueWithIdentifier: @"presentSegue2" sender: self];
                }
                else if ([currentBeaconMinor floatValue] == 328)
                {
                    NSLog(@"328 328 328");
                    //[self performSegueWithIdentifier: @"presentSegue3" sender: self];
                }

                break;
            }

但那仍然不起作用:(((我疯了.我的应用程序首先选择最接近的灯塔.在该应用程序之后始终保持相同的信标并且永远不会改变.我将信标移动到设备附近但是nslog总是向我发送相同的次要号码请你能给我一些帮助吗？我确定我做错了什么.

Answer 1

每个信标有3条信息 - 一个UUID,一个主要号码和一个次要号码.创建信标区域时,必须至少指定UUID.您可以选择指定主要值和次要值.iOS将在后台扫描的信标区域数量有限(我相信它是20),因此通常最好在您的区域注册中尽可能广泛,然后确定何时通知您是否感兴趣在可见的灯塔中.

所有Estimote信标都具有相同的UUID,因此如果您注册仅具有UUID的区域,则只要您处于任何 Estimote信标的范围内,您的应用就会得到通知.我可以看到你的三个信标都使用了主要的12800,所以你可以简单地创建一个指定UUID和专业的区域,然后只要看到那些带有这些值的信标就会得到通知 - 或者你可以像你做的那样做并为三个信标中的每一个注册特定区域.

您只需要一个EstBeaconManager实例来管理所有区域.

每当你进入或退出你的区域didEnterRegion和didExitRegion方法将被调用.didRangeBeacons如果您目前正在测量信标,也会调用您的方法.

在这些委托方法中,您需要检查主要和次要(嗯,实际上只是次要,因为在您的情况下主要总是相同)值,以确定您要采取的操作.您还可以检查区域标识符字符串以确定哪个信标可见.

请注意,多个信标可能在范围内,因此您可能需要检查邻近度以确定要采取的操作.

最后,虽然您定义了三个区域,但您没有对它们进行测距/监控,因此请将您更改viewWillAppear为

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [self.beaconManager startRangingBeaconsInRegion:region];
    [self.beaconManager startMonitoringForRegion:region];

    [self.beaconManager startRangingBeaconsInRegion:region2];
    [self.beaconManager startMonitoringForRegion:region2];

    [self.beaconManager startRangingBeaconsInRegion:region3];
    [self.beaconManager startMonitoringForRegion:region3];


}
