前序
纵观每个优质项目,无论web端还是native原生应用开发,弹窗都是不可忽视的一环,能很大程度上直接决定用户体验。如:微信、支付宝、ios都有很成熟的一套弹窗UI展示场景。
最近一直沉迷在react-native开发研究中,学习起来发现没有想象的难,不过也采坑了不少。鉴于之前有基于h5和小程序技术开发过自定义弹窗的经验,就想着用react-native技术实现msg信息框|alert提示框|confirm确认框|toast弱提示/loading|仿ios、android弹窗,就有了这个rnPop弹窗组件RN版。
效果图
仿真模拟器上画质有些次,真机实测完美,可忽略这一点
看了上图,是不是觉得调用方式还挺多的,没错,很丰富的应用场景
◆ rnPop弹窗组件目录结构
◆ 引入方式及调用
import RNPop from '../utils/rnPop/rnPop.js'
显示:this.refs.rnPop.show({...options});
隐藏:this.refs.rnPop.hide();
/** * --------- react-native弹窗演示(普通型弹窗) --------- */ //msg提示 handlePress01 = ()=> { let rnPop = this.refs.rnPop rnPop.show({ anim: 'fadeIn', content: 'msg消息提示框(5s后窗口关闭)', shade: true, shadeClose: false, time: 5, xtime: true, }); } //msg提示(黑色背景) handlePress02 = ()=> { let rnPop = this.refs.rnPop rnPop.show({ content: '自定义弹窗背景', shade: false, style: {backgroundColor: 'rgba(17,17,17,.7)', borderRadius: 6}, contentStyle: {color: '#fff', padding: 10}, time: 2 }); }
toast弱提示可自定义loading | success | info | error四种图标
//Toast演示 handlePress15 = ()=> { let rnPop = this.refs.rnPop rnPop.show({ skin: 'toast', content: '操作成功', icon: 'success', //success | info | error | loading shade: false, time: 3 }); }
//ios居中对话框 handlePress17 = ()=> { let rnPop = this.refs.rnPop rnPop.show({ skin: 'footer', position: 'center', content: '如果您喜欢探鱼,请给我们个好评,也可以直接反馈意见给我们!', shadeClose: true, btns: [ { text: '给个好评', style: {color: '#30a4fc'}, onPress() { console.log('您点击了给个好评!'); //回调函数 rnPop.show({ anim: 'fadeIn', content: '感谢您的好评,我们会再接再厉!', shade: true, time: 3 }); } }, { text: '不好用,我要提意见', style: {color: '#30a4fc'}, onPress() { // ... } }, { text: '残忍的拒绝', style: {color: '#30a4fc'}, onPress() { rnPop.close(); } } ] }); }
