UIRefreshControl iOS 6 xcode [英] UIRefreshControl iOS 6 xcode

问题描述

有没有人举例说明如何在xcode中实现新的 UIRefreshControl 。我有一个显示推文的 UITableViewController ，希望能够下拉并刷新。

Does anyone have a short example of how to implement the new UIRefreshControl into xcode. I have a UITableViewController which displays Tweets, want to be able to pull down and refresh.

推荐答案

你可以在你的 viewDidLoad 中设置它，如果你有一个 UITableViewController ：

You can just set it up in your viewDidLoad, if you have a UITableViewController:

UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
[refreshControl addTarget:self action:@selector(refresh)
         forControlEvents:UIControlEventValueChanged]; 
self.refreshControl = refreshControl;

然后你可以在这里刷新东西：

Then you can do your refresh stuff here:

-(void)refresh {
    // do something here to refresh.
}

完成刷新后，请致电 [self .refreshControl endRefreshing]; 停止刷新控制，正如rjgonzo所指出的那样。

When you are done with refreshing, call [self.refreshControl endRefreshing]; to stop the refresh control, as pointed out by rjgonzo.
