jmessage-phonegap-plugin sendImageMessage IOS发送图片

用 jmessage-phonegap-plugin 插件发送图片时，
同样的参数，android平台能正常发送并显示图片，IOS平台就不行

IOS 图片应该上传了，就是不显示

JMessage.sendImageMessage({
type: 'single',
username: this.username,
path: path,
messageSendingOptions: JMessage.messageSendingOptions
},
(msg: any = {}) => {
msg.fileUrl = msg.thumbPath;
}, (error) => {
console.log(error)
})
