uni.chooseMedia({
  count: 1,
  mediaType: ["image", "video"],
  sourceType: ["camera"],
  maxDuration: 30,
  camera: "back",
   sizeType: ["compressed"],
  success: (res) => {
   console.log("相册选择媒体成功success", res)
  },
  fail: (error) => {
    console.log("相册选择媒体失败fail", error)
  },
  complete: (res) => {
    console.log("相册选择媒体complete", res)
  }
})
iOS系统为18版本，当sourceType配置为单个配置时success/fail/complete方法都不被执行，该问题为必现的缺陷。
