Objective c Socket Mobile SocketScan SDK和Swift

我正在尝试将SocketScan SDK与用Swift编写的应用程序一起使用。使用桥接头，Objective-C代码很容易导入。但是，在运行应用程序时，它在OnDevicarrival阶段崩溃，Xcode引用了“无法识别的选择器”。也就是说，ScanApi打开并运行，当设备到达时，应用程序崩溃，出现以下错误：

-[SocketConnect.ViewController onDeviceArrival:设备：]：发送到实例0x15550e670的无法识别的选择器 *由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：'-[SocketConnect.ViewController onDeviceArrival:Device::]：无法识别的选择器发送到实例0x15550e670' *第一次抛出调用堆栈： （0x185a9259c 0x1961e40e4 0x185a99664 0x185a96230 0x18599ab6c 0x1000b2798 0x1000b2148 0x1000b1e24 0x1000a2dc4 0x1000a2e0c 0x186966e18 0x185a4a8d8 0x185a4a588 0x185a47fd4 0x1859750a4 0x18eb175a4 0x18a2aa3c0 0x1000a6ae8 0x1000a6b28 0x196852a08） libc++abi.dylib:以NSException类型的未捕获异常终止

以下是API提供的OnDevicarrival的代码片段

-(SKTRESULT)handleDeviceArrival:(id<ISktScanObject>)scanObj{
SKTRESULT result=ESKT_NOERROR;
id<ISktScanDevice> scanDevice=[SktClassFactory createDeviceInstance:_scanApi];
NSString* name=[[scanObj Msg]DeviceName];
NSString* guid=[[scanObj Msg]DeviceGuid];
long type=[[scanObj Msg]DeviceType];

// create a new DeviceInfo object
DeviceInfo* deviceInfo=[[DeviceInfo alloc]init:scanDevice name:name type:type];

// open the scanner which means that we can now receive
// any event (such as DecodedData event) from this scanner
result=[scanDevice open:guid];

NSLog(@"!!!device connected!!!!");

if(SKTSUCCESS(result)){
NSLog(@"SKTSUCCESS!");
    if(_noDeviceText!=nil)
        [_deviceInfoList removeObjectForKey:_noDeviceText];

    // add the device info into the list
    [_deviceInfoList setValue:deviceInfo forKey:[NSString stringWithFormat:@"%@",scanDevice]];
    NSLog(@"device info added to list.");
}

// notify the ScanApiHelper user a scanner has connected to this host
NSLog(@"about to notify ScanApiHelper that the scanner has been connected.");

if(_delegate!=nil)
    NSLog(@"delegate is NOT nil");

   [_delegate onDeviceArrival:result Device:deviceInfo];
 NSLog(@"ScanApi has been notified");
enter code here`#if __has_feature(objc_arc)
#else 
[deviceInfo release];// we don't keep this object since we couldn't open the scanner
 NSLog(@"device info released");
#endif
return result;
}

-（SKTRESULT）handleDeviceArrival:（id）scanObj{
SKTRESULT结果=ESKT_NOERROR；
id ScandDevice=[SktClassFactory createDeviceInstance:\u scanApi]；
NSString*name=[[scanObj Msg]DeviceName]；
NSString*guid=[[scanObj Msg]设备guid]；
long type=[[scanObj Msg]设备类型]；
//创建新的DeviceInfo对象
DeviceInfo*DeviceInfo=[[DeviceInfo alloc]初始化：扫描设备名称：名称类型：类型]；
//打开扫描仪，这意味着我们现在可以接收
//来自此扫描仪的任何事件（如DecodedData事件）
结果=[scanDevice open:guid]；
NSLog（@“！！！设备已连接！！！！”）；
if（SKTSACCESS（结果））{
NSLog（@“sktsucess！”）；
如果（_noDeviceText！=nil）
[_deviceinfo-list-removeObjectForKey:_noDeviceText]；
//将设备信息添加到列表中
[_deviceInfo列表集合值：deviceInfo forKey:[NSString stringWithFormat:@“%@”，ScandDevice]]；
NSLog（@“设备信息添加到列表中”）；
}
//通知ScanApiHelper用户扫描仪已连接到此主机
NSLog（@“即将通知ScanApiHelper扫描仪已连接。”）；
如果（_delegate！=nil）
NSLog（@“委托不为零”）；
[_delegateondevicearrival:result Device:deviceInfo]；
NSLog（“已通知ScanApi”）；
在此处输入代码“#如果uu具有u特性（objc_弧）
#否则
[deviceInfo release]；//由于无法打开扫描仪，因此无法保留此对象
NSLog（“设备信息发布”）；
#恩迪夫
返回结果；
}

日志打印所有内容，包括“委托不为零”

是否有人对在Swift环境中运行的SocketScan SDK有问题，如果有，有什么建议可以解决这个问题？

我也有同样的问题。代表func onDeviceArrival的选择器“Device”在Swift中为小写

将ScanAPI/lib/ScanApiHelper.h（ScanApiHelperDelegate）中的“设备”更改为“设备”，如下所示：

然后更改函数handleDeviceArrival中ScanAPI/lib/ScanApiHelper.mm中的调用

[_delegate onDeviceArrival:result device:deviceInfo];

希望这有帮助

这是Socket Mobile直接提供的修复程序，与Mike的回答一致

杰出的我遇到了与“OnDecodedata”相同的问题，需要类似的修复。感谢您的跟进和发布解决方案。我将其替换为一个统一的变化差异，因为我认为它更容易解析。
