從iPhone的歷代機(jī)型配置中猫胁，可以看出在iPhone6及以上機(jī)型都擁有了支持NFC功能的固件，但是一直不開放給開發(fā)者使用，直到iOS11才開放僅有的具有讀取NDEF格式的功能磕道，并且需要iPhone7或者iPhone7 Plus以上的機(jī)型才支持使用示弓。干貨來了.........
1讳侨、配置開發(fā)證書記得選上標(biāo)記項(xiàng)
2.在TARGETS>Capabilities中打開Near Field Communication
3.在TARGETS>Info中配置NFC使用說明
4.代碼邏輯
導(dǎo)入#import <CoreNFC/CoreNFC.h>
#import "ViewController.h"
#import <SVProgressHUD.h>
#import <CoreNFC/CoreNFC.h>
@interface ViewController ()<NFCNDEFReaderSessionDelegate>

5.下面是操作效果圖！老鐵記得準(zhǔn)備標(biāo)簽啊
