presentView 不是全屏

1	nav.modalPresentationStyle = UIModalPresentationFullScreen;

search bar 左侧icon位置偏移
在uiimageview 外面套一层uiview 设置uiview的职位

UIView * iconOutView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 40, 30)];
UIImageView* iconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"搜索图标"]];
iconView.center = CGPointMake(iconOutView.frame.size.width/2,iconOutView.frame.size.height/2);
[iconOutView addSubview:iconView];

self.leftView = iconOutView;
self.leftViewMode = UITextFieldViewModeAlways;

launch img要被禁用了需要配置成launch screen
先创建一个launch screen文件
点击xcode 右上角的加号添加imageview
添加约束显示

$ npm install weixin-js-sdk –save

引入wechat js文件

import wx from 'weixin-js-sdk'

const wxPlugin = {}
wxPlugin.install = function (Vue, options) {
  function extend (obj1, obj2) {
    for (var k in obj2) {
      if (obj1.hasOwnProperty(k)) {
        if (isObject(obj2[k])) {
          extend(obj1[k], obj2[k])
        } else {
          obj1[k] = obj2[k]
        }
      } else {
        obj1[k] = obj2[k]
      }
    }
    return obj1
  }
  function getProp (obj, str) {
    var result = extend({}, obj)
    var array = str.split('.')
    for (var i = 0; i < array.length; i++) {
      if (result[array[i]]) {
        result = result[array[i]]
      } else {
        result = result[array[i]]
        break
      }
    }
    return result
  }
  // 判断options.config的数据类型
  if (!options.config) {
    console.error('wxPlugin Error：config属性必须为一个对象或者promise，不能为空')
    return
  }
  // 如果config为一个对象
  if (Object.prototype.toString.call(options.config) === '[object Object]') {
    wxConfig(options.config)
  }
  // 如果config为一个promise
  if (options.config instanceof Promise) {
    options.config.then(function (res) {
      var config
      if (options.path) {
        config = getProp(res, options.path)
              } else {
        config = res.data
      }
      wxConfig(config)
    })
  }
  function wxConfig (config) {
    wx.config({
      debug: false,
      appId: config.appId,
      timestamp: config.timestamp,
      nonceStr: config.nonceStr,
      signature: config.signature,
      jsApiList: options.actions
    })
    wx.error(function (err) {
      console.error(err)
    })
  }
  Vue.prototype.wx = wx
}
export default wxPlugin

main.js中引用

import wxPlugin from 'common/js/wechatJs.js'
const options = {
  config: api.me.getWechatJsConfig({url: location.href}),
  // 如果config是promise，path需要指定如何从promise返回值中拿到符合格式的object;
  // 如果config是一个object，则无需指定path值
  path: 'data',
  // 声明用到的微信api
  actions: ['onMenuShareAppMessage', 'onMenuShareTimeline']
}

Vue.use(wxPlugin, options)

页面中引用

wx_share () {
  this.wx.ready(function () {
    // 分享给朋友
    this.wx.onMenuShareAppMessage({
      title: '问题反馈',
      desc: '问题反馈',
      link: location.href,
