How do I "hide" a UIRefreshControl?
提问by Doug Smith
Occasionally my table view won't be connected to a service to refresh, and in that case, I don't want the UIRefreshControl to be present.
有时，我的表视图不会连接到要刷新的服务，在这种情况下，我不希望 UIRefreshControl 出现。
After I add it in viewDidLoad, I've tried hiding it under certain circumstances with setEnabled:and setHidden:but neither seems to work.
在 viewDidLoad 中添加它后，我尝试在某些情况下使用setEnabled:和隐藏它，setHidden:但似乎都不起作用。

Try setting your table view controller's refreshControlproperty to nil.
尝试将您的表视图控制器的refreshControl属性设置为 nil。

Try this:
尝试这个：
[self.refreshControl removeFromSuperview];
self.refreshControl = nil;

You have several ways to do this. I think the best way is to do a check in the viewDidLoad method with:
您有几种方法可以做到这一点。我认为最好的方法是检查 viewDidLoad 方法：
if (condition){
//attach refreshControl
}
if this isn't possible the best way is put this code where you want to hide the refresh (I think in viewWillAppear method in if condition)
如果这不可能，最好的方法是将此代码放在要隐藏刷新的位置（我认为在 if 条件下的 viewWillAppear 方法中）
//End refresh control
[self.refreshControl endRefreshing];
//Remove refresh control to superview
[self.refreshControl removeFromSuperview];

There's a very simple solution you can try: [self.refreshControl removeFromSuperview];
您可以尝试一个非常简单的解决方案： [self.refreshControl removeFromSuperview];

I had bad experience when set tableView.refreshConrol = nil, because when I set it back to old refreshControl, it started animation only in a second, so it looked not good, so when I need to disable refreshControlI use:
我在 settableView.refreshConrol = nil时体验不好，因为当我将它设置回 old 时refreshControl，它只在一秒钟内启动动画，所以看起来不太好，所以当我需要禁用时，refreshControl我使用：
tableView.refreshControl?.endRefreshing()
tableView.refreshControl?.alpha = 0
when I need it back I use:
当我需要它时，我使用：
tableView.refreshControl?.alpha = 1
// and if I need to show refreshing indicator immediately I write:
tableView.refreshControl?.beginRefreshing()
P.S. Setting isHidden, isEnabled, isUserInteractionEnableddidn't help
PS设置isHidden, isEnabled, isUserInteractionEnabled没有帮助

I solved this problem by calling "yourRefreshControl".endEditing()inside the refresh function.
我通过调用"yourRefreshControl".endEditing()refresh 函数解决了这个问题。

An old question, but I was looking for an answer and nothing worked exactly like I wanted.
一个老问题，但我一直在寻找答案，但没有任何效果完全符合我的要求。
This is what worked for me:
这对我有用：
Swift 4
斯威夫特 4
func createRefreshControl() {
refreshControl = UIRefreshControl()
refreshControl?.addTarget(self, action: #selector(self.myTableRefreshFunction), for: UIControlEvents.valueChanged)
refreshControl?.tintColor = UIColor.white
refreshControl?.endRefreshing()
}
func removeRefreshControl() {
refreshControl?.removeTarget(self, action: #selector(self.myTableRefreshFunction), for: UIControlEvents.valueChanged)
refreshControl = nil
}
I call createRefreshControl() when I want the control created, and removeRefreshControl when I want it removed.
当我想要创建控件时，我调用 createRefreshControl()，当我想要删除它时调用 removeRefreshControl。
I had to remove the same target I initially added to the refresh control, otherwise it would refresh one time before it was actually removed.
我必须删除最初添加到刷新控件的相同目标，否则它会在实际删除之前刷新一次。

You can not remove the UIRefreshControl using setEnabled:NO,so to this you have to remove it from it's superview.I have tried a sample using Reachability class provided by Apple.
To add UIRefreshControl you can use this:
您无法使用 删除 UIRefreshControl setEnabled:NO，因此您必须将其从它的超级视图中删除。我尝试了使用 Apple 提供的 Reachability 类的示例。
要添加 UIRefreshControl，您可以使用：
UIRefreshControl *refContr=[[UIRefreshControl alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];
[refContr setTintColor:[UIColor blueColor]];
[refContr setBackgroundColor:[UIColor greenColor]];
[self.view addSubview:refContr];
[refContr setAutoresizingMask:(UIViewAutoresizingFlexibleRightMargin|UIViewAutoresizingFlexibleLeftMargin)];
[refContr addTarget:self action:@selector(refresh:) forControlEvents:UIControlEventValueChanged];
Then Implemented reachability class notification :
然后实现可达性类通知：
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reachabilityChanged:) name:kReachabilityChangedNotification object:nil];
You can do it by using bool flag to check the connectivity ,Here i'm providing this example using reachability class by apple to check my connectivity.
您可以通过使用 bool 标志来检查连接来实现，这里我提供了这个示例，使用 Apple 的可达性类来检查我的连接。
switch (netStatus)
{
case NotReachable: {
for (UIRefreshControl *subView in [myView subviews]) {
if ([subview isKindOfClass:[UIRefreshControl class]]) {
[subView removeFromSuperview];
}
}
//or you could use [UIRefreshControl setHidden:YES];
connectionRequired = YES;
break;
}
case ReachableViaWiFi: {
for (UIRefreshControl *subView in [myView subviews]) {
if ([subview isKindOfClass:[UIRefreshControl class]]) {
[subview removeFromSuperview];
}else{
[self.view addSubview:refContr];
}
//or you could use [UIRefreshControl setHidden:NO];
break;
}
}
Hope this will work for you.
希望这对你有用。

I solved it this way:
我是这样解决的：
-(void)updateUIWithAuthState:(BOOL)isAuthenticated {
self.loginButton.enabled = !isAuthenticated;
self.loginButton.tintColor = isAuthenticated ? [UIColor clearColor] : nil;
self.logoutButton.enabled = isAuthenticated;
self.logoutButton.tintColor = isAuthenticated ? nil : [UIColor clearColor];
self.tableView.userInteractionEnabled = isAuthenticated;
self.data = nil;
[self.tableView reloadData];
}
