如何使用不同的图像和位置自定义UIRefreshControl？ [英] How to customize UIRefreshControl with different image and position?

问题描述

我一直在环顾四周，但找不到任何关于此事的好消息。

I have been looking around but couldn't find anything good about this.

我想用不同的装载机等自定义默认的 UIRefeshControl 到目前为止，我只能更改 tintColor & attributionTitle 属性和我找到的大多数代码基本上都是创建一个新的pulltorefresh效果，但我想要的只是使用 UIRefreshControl 并稍微自定义。

I would like to customize the default UIRefeshControl with different loader, etc. So far I can only change tintColor & attributedTitle properties and most code I found are just basically creating a new "pulltorefresh" effect but what I want is to just use the UIRefreshControl and customize it a bit.

这可能吗？

推荐答案

您无法在不访问私有API的情况下添加不同的加载程序，但您可以添加背景图像：

You can't add different loader without accessing private APIs, but you can add background image:

UIImageView *rcImageView =
    [[UIImageView alloc] initWithImage:
        [UIImage imageNamed: @"refreshControl.png"]];
[self.refreshControl insertSubview:rcImageView atIndex:0];

假设self是UITableViewController子类的实例。

assuming self is an instance of UITableViewController subclass.

您需要的图像尺寸为320x43px（@ 2x 640x86px），加载器动画将覆盖中间区域（约35px）。

Image size you need is 320x43px (@2x 640x86px), the middle area (approximately 35px) will be covered by the loader animation.
