如何在iOS 6/7中缩短拉动距离以激活拉动刷新操作？ [英] How Do I Shorten the Pull Distance to Activate the Pull to Refresh Action in iOS 6/7?

问题描述

嘿StackOverflow人，

Hey StackOverflow People,

我一直试图弄清楚这个问题已经有一段时间但无济于事，我需要一些帮助。我有一个 UITableView 靠近我的应用程序底部，并且用户没有足够的屏幕距离来进行刷新。有没有人知道如何缩短在 UITableView上激活拉动刷新动作所需的距离（通过iOS 6/7中的 UIRefreshControl ） 和 UIWebView ？

I've been trying to figure out this question for some time now but to no avail and I need some help. I have a UITableView close to the bottom of my app and there's not enough screen distance for the user to engage the refresh. Does anybody know how I can shorten the distance it takes to activate the pull to refresh action (via a UIRefreshControl in iOS 6/7) on a UITableView andUIWebView?

先谢谢大家！

推荐答案

根据Apple Docs，我认为没有办法修改 UIRefreshControl 参数。< br>

As per the Apple Docs, I don't see any way to modify UIRefreshControl parameters.

使用第三方组件 ODRefreshControl （自定义滚动距离以激活刷新，修改 #define kMaxDistance 常量）。

Use a third-party component like ODRefreshControl (to customize the scroll-distance in order to activate the refresh, modify the #define kMaxDistance constant).

不要使用 UIRefreshControl 而是在 -scrollViewDidScroll 方法中实现自己的逻辑，如：

Don't use the UIRefreshControl and instead implement your own logic in the -scrollViewDidScroll method like:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    if ((scrollView.contentOffset.y + scrollView.frame.size.height) >= scrollView.contentSize.height) {
        //refresh logic
    }
}
