Swift - 搜索时禁用 refreshControl

问题描述

在搜索过程中，我想禁用下拉刷新机制.所以我禁用了刷新控件并将其删除.但是当下拉刷新时，beginRefresh 方法被调用，单元格会像刷新一样保持关闭 2 秒.

During the search I want to disable the pull to refresh mechanism. So I disabled the refresh control and removed it. But when pull down to refresh the beginRefresh method is called and the cells keep being down for 2 seconds like there is a refresh.

func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {
    resultSearchController.searchBar.selectedScopeButtonIndex = 0
    refreshControl!.enabled = false
    refreshControl?.removeFromSuperview()
    return true
}

推荐答案

搜索时检查refreshControl是否有superView并从superView中移除，搜索完再添加，条件如下:

When search then check if refreshControl has superView and Remove from superView After search End Add it again, the condition will look like :

  if self.refreshControl.isDescendant(of: self.tblView) {
      self.refreshControl.removeFromSuperview() 
  }
