Question

我有一个非常奇怪的问题，如果我插入IDTech Shuttle我的视图控制器加载后;它按预期连接。（我正在使用自动连接功能）。

但是如果在我启动视图控制器/应用程序之前连接了设备;它根本不会调用umConnection_connected。（它确实称为附加）

这也发生在随SDK提供的演示应用中。（在iOS 8中运行，但在9中运行;但仍然是同一问题）

这在7.5版本中没有发生，我需要升级到7.16才能兼容苹果。

代码：

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    self.navigationController.toolbarHidden = NO;
    self.navigationController.navigationBarHidden = YES;

    //init alert views
    prompt_changeStoreUrl = [[UIAlertView alloc] initWithTitle:@"Confirmation"
                                                       message:@"Are you really sure you want to change store URL?"
                                                      delegate:self
                                             cancelButtonTitle:@"No"
                                             otherButtonTitles:@"Yes", nil];
    [self umsdk_activate];

}

-(void) umsdk_activate {

    NSLog(@"ACTIVATE");

    //register observers for all uniMag notifications
    [self umsdk_registerObservers:TRUE];


    //enable info level NSLogs inside SDK
    // Here we turn on before initializing SDK object so the act of initializing is logged
    [uniMag enableLogging:TRUE];

    //initialize the SDK by creating a uniMag class object
    uniReader = [[uniMag alloc] init];

     //Set the reader type to UMREADER_SHUTTLE
    uniReader.readerType = UMREADER_SHUTTLE;

    /*
     //set SDK to perform the connect task automatically when headset is attached
     */

     [uniReader setAutoConnect:TRUE];

    //set swipe timeout to infinite. By default, swipe task will timeout after 20 seconds
    [uniReader setSwipeTimeoutDuration:0];

    //make SDK maximize the volume automatically during connection
    [uniReader setAutoAdjustVolume:TRUE];

}


//called when the connection task is successful. SDK's connection state changes to true
- (void)umConnection_connected:(NSNotification *)notification
{
    NSLog(@"CONNECTED");

    [[[[iToast makeText:@"Connected Credit Card Reader"] setGravity:iToastGravityCenter] setDuration:iToastDurationNormal] show];
}


/called when uniMag is physically attached
- (void)umDevice_attachment:(NSNotification *)notification
{
    NSLog(@"ATTACH");
}

//called when uniMag is physically detached
- (void)umDevice_detachment:(NSNotification *)notification
{
    NSLog(@"DETACH");
}

#pragma mark attachment

//called when uniMag is physically attached
- (void)umDevice_attachment:(NSNotification *)notification
{
    NSLog(@"ATTACH");
}

以下是两种方案的调试日志：

Answer 1

另一种修复方法是此版本的API更改。你需要这样做：

[uniReader startUniMag: TRUE];

以便自动连接工作。

如果有人在iOS SDK中遇到依赖于自动连接的错误。我发现了以下7.9版本：

https://github.com/MercuryPay/IDTech.Shuttle.ObjC/tree/570487a30dd0ddbf646a0f788d37b257de0a0b86/HC.POS/uniMag-SDK

（我确保在特定提交时链接，以防将来更新此存储库）。这没有自动连接功能，并且支持64位。

升级UNIMAG 7.5 - ＆gt; 7.16自动连接错误
