问题描述
我有一个UITableViewController作为UINavigationController中的根视图控制器，UINavigationController又是UITabBarController中的一个视图控制器。所有这些都连接在Storyboard中。
I have a UITableViewController as the root view controller in a UINavigationController, which is in turn one of the view controllers in a UITabBarController. All hooked up in Storyboard.
我也在故事板中为我的表配置了UIRefreshControl，通常在拉动时看起来应该是这样：
I've configured the UIRefreshControl for my table in Storyboard as well, and normally it looks like it should when pulling:
但是，如果我在其他标签之间切换一次或两次，它看起来像这样：
However, if I switch between my other tabs once or twice, it looks like this:
它没有旋转或任何东西，只是卡住了满，它一直保持这种状态直到我完全拉并触发刷新。
It's not spinning or anything, just stuck "full", and it stays that way until I pull fully and trigger a refresh.
任何想法或建议都表示赞赏。
Any ideas or suggestions appreciate.
推荐答案
我知道这已经太晚了，但是我觉得迟到总比没有好。
I know this is incredibly late, but I figure better late than never.
不幸的是，没有一个给定的答案对我有用。唯一可行的是viewWillAppear中的这段可怕的代码：
Unfortunately, none of the given answers worked for me. The only thing that worked was this awful piece of code in viewWillAppear:
self.refreshControl = nil;
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
[refreshControl addTarget:self action:@selector(refreshFunction) forControlEvents:UIControlEventValueChanged];
self.refreshControl = refreshControl;
基本上每次出现视图时我都会重新创建UIRefreshControl。虽然在发出以下警告时它仍然有效：
Basically I recreate the UIRefreshControl every time the view is going to appear. It works, albeit while giving the following warning:
我真的很惊讶这仍然是个问题（现在仍然在iOS 9中看到这个） 。希望这可能对其他人有所帮助。
I'm honestly surprised this is still an issue (still seeing this in iOS 9 now). Hopefully this may be helpful to some other people.
