I'm trying to set a tintColor on my UIRefreshControl (building on iOS 7).
I enabled refreshing for the tableViewController in storyboard, then in my ViewController viewDidLoad
method i did the following:
[self.refreshControl setTintColor:[UIColor redColor]];
So now, when I pull to refresh, the color of the refresh control is red indeed:
I want my view to update automatically when it appears, so I did:
- (void)viewDidAppear:(BOOL)animated{
[self.refreshControl beginRefreshing];
}
It didn't show the spinning wheel, according to https://stackoverflow.com/a/16250679/1809736, I added
[self.tableView setContentOffset:CGPointMake(0, -self.refreshControl.frame.size.height) animated:NO];
to force show it. It shows it, but now it is back to default color:
If I try manually to pull to refresh afterwards, it is red.
I tried building it on iOS6 and it works as it should, so is that an iOS7 bug?
P.S.: it is not a problem with the simulator, I tried building it on device, same bug.
P.P.S: I built an example project, can you tell me if you have the same bug or if there is a problem in my code? Here is the link: http://d.pr/f/pGrV
Thanks a lot !
Hey just stumbled into this exact issue.
Interestingly I fixed my code by setting the contentOffset first then calling beginRefreshing
if(self.tableView.contentOffset.y == 0){
self.tableView.contentOffset = CGPointMake(0, -self.refreshControl.frame.size.height);
[self.refreshControl beginRefreshing];
}
You may want to animate this process:
[UIView animateWithDuration:0.25 delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations:^(void){
self.tableView.contentOffset = CGPointMake(0, -self.refreshControl.frame.size.height);
} completion:^(BOOL finished) {
[self.refreshControl beginRefreshing];
}];
Hope this helps you.

SWIFT SOLUTION !
Insert the following code in the viewDidLoad
:
self.refreshControl.tintColor = UIColor.orangeColor()
self.tableView.contentOffset = CGPointMake(0, -self.refreshControl.frame.size.height)
self.refreshControl.beginRefreshing()
Swift 3.1
self.refreshControl.tintColor = UIColor.orange
self.tableView.contentOffset = CGPoint(x:0, y:-self.refreshControl.frame.size.height)
self.refreshControl.beginRefreshing()
@william-george's answer set me in the right direction, but was giving me weird autolayout animation issues.
So here's the version that worked for me:
- (void)programaticallyRefresh {
// Hack necessary to keep UIRefreshControl's tintColor
[self.scrollView setContentOffset:CGPointMake(0, -1.0f) animated:NO];
[self.scrollView setContentOffset:CGPointMake(0, -self.refreshControl.frame.size.height) animated:YES];
[self.refreshControl beginRefreshing];
[self refresh];
}
-refresh
is the method tied to the UIRefreshControl
.
