一.环境
系统:iOS 11+;(现在还没推送,可以使用iTunes通过固件升级);
开发工具:Xcode9.0+;
iOS11固件跟Xcode9.0测试版下载地址 https://developer.apple.com/download/
支持机型:iPhone7 ,iPhone7P;
二.配置项目
1.进入开发者中心设置AppID支持NFC Tag Reading,并且设置项目的Bundle Identifier跟新设置的AppID同步.
2.创建 .entitlements 文件(可以直接创建,也可以到target->capabilities里面打开任意开关,.entitlements文件会自动创建)。
右键 .entitlements文件点击 “Open As Source Code” 添加以下代码:
添加成功后entitlements文件显示如下:
然后在Info.plist文件中添加"Privacy - NFC Scan Usage Description"权限,当使用NFC时，将向用户显示此消息.
三.使用
导入 CoreNFC.h (只有在真机导入才不报错)
遵循协议 NFCNDEFReaderSessionDelegate
@property (nonatomic, strong) NFCNDEFReaderSession *ndefSession;
//床架会话
- (void)creatReader {
self.ndefSession = [[NFCNDEFReaderSession alloc] initWithDelegate:self queue:nil invalidateAfterFirstRead:NO];
[_ndefSession beginSession];
}
//代理获取传输的信息
- (void)readerSession:(NFCNDEFReaderSession *)session didDetectNDEFs:(NSArray*)messages
{
NSLog(@"Called: %s", __func__);
for(NFCNDEFMessage *message in messages)
{
for(NFCNDEFPayload *payload in message.records)
{
NSLog(@"TNF:%d", payload.typeNameFormat);
NSLog(@"Type: %@", payload.type.description);
NSLog(@"payload: %@", payload.payload.description);
dispatch_async(dispatch_get_main_queue(),^{
NSString *str =[NSString stringWithFormat:@"TNF: %d\nType: %@\nPayload: %@", payload.typeNameFormat, payload.type.description, payload.payload.description];
});
}
}
}
//获取错误信息
- (void)readerSession:(NFCNDEFReaderSession *)session didInvalidateWithError:(NSError *)error
{
NSLog(@"Called: %s", __func__);
NSLog(@"error: %@", error.localizedDescription);
dispatch_async(dispatch_get_main_queue(),^{
});
_ndefSession = nil;
}
