同样的代码在安卓机上和苹果上面是两个效果，无论设置girdSize为多小，安卓机都不为所动 let mapContext=wx.createMapContext('map', this); //设置点聚合 mapContext.initMarkerCluster({ gridSize:10, complete:(e)=>{ console.log(e) } }) 左为苹果，右为安卓 [图片]

这个方法我发现不止我一个人调用没生效- - 这里提供个暂时方案 因为注销不掉nfc监听事件，只好确保整个生命周期内仅有一个nfc监听事件，所以全局定义： 1.一个变量nfcState（用于判断监听事件是否开启 2.一个方法（通过route事件去调用页面的scanNfc()，具体逻辑写在scanNfc内 nfcInit() { if (!this.state.nfc) { this.state.nfc = wx.getNFCAdapter(); } let ab2str = (buffer) => {//转码 let dataView = new DataView(buffer); let str = ''; for (let i = 0; i < dataView.byteLength; i++) { let num16 = dataView.getUint8(i); if (num16 / 16 >= 10) { str += String.fromCharCode(65 + parseInt(num16 / 16) - 10); } else { str += String.fromCharCode(48 + parseInt(num16 / 16)); } if (num16 % 16 >= 10) { str += String.fromCharCode(65 + parseInt(num16 % 16) - 10); } else { str += String.fromCharCode(48 + parseInt(num16 % 16)); } } return str; }; let errCode = { 13000: '本设备不支持NFC', 13001: '系统NFC开关未打开', 13010: '未知错误', 13019: '用户未授权', 13021: '已经开始NFC扫描', 13018: '尝试在未开始NFC扫描时停止NFC扫描', 13022: '标签已经连接', 13023: '尝试在未连接标签时断开连接', 13013: '未扫描到NFC标签', 13014: '无效的标签技术', 13015: '从标签上获取对应技术失败', 13024: '当前标签技术不支持该功能', 13017: '相关读写操作失败', 13016: '连接失败', } if (!this.state.nfcState) { this.state.nfc.startDiscovery({ success: res => { this.state.nfcState = true; this.state.nfc.onDiscovered(res => { console.log('nfc回调', res); let code = ab2str(res.id); // this.$msg('扫描成功！'); let routes = getCurrentPages(); // console.log(routes[routes.length-1].$vm.testNfc) if (routes[routes.length - 1].$vm.scanNfc) { routes[routes.length - 1].$vm.scanNfc(code) } }); }, fail: err => { console.log('failed to discover:', err); let content = errCode[err.errCode]; wx.showModal({ title: '错误', showCancel: false, content, success: function(res) { if (res.confirm) { console.log('用户点击确定'); let routes = getCurrentPages(); // console.log(routes[routes.length-1].$vm.testNfc) if (routes[routes.length - 1].$vm.openNfcFail) { routes[routes.length - 1].$vm.openNfcFail() } } } }); } }); } }
