NSInvalidArgumentException - receiver has no segue

问题:

I have been trying everything for hours, and nothing's worked. I am trying to segue between two view controllers, from one tableViewController to another tableViewController. The segue is hooked up to the top level view, not the tableviewcell. The identifier that was set in Xcode is identical to the one used in the code (copy and pasted). It was working fine last night, but now i can't seem to get it to segue without crashing.

here are the methods in which the segue is called

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    self.photoList = [FlickrFetcher photosInPlace:[self.topPlacesList objectAtIndex:indexPath.row] maxResults:50];
    NSLog(@"photolist %@", self.photoList);

    NSLog(@"here");

    [self performSegueWithIdentifier:@"segue1" sender:self];
    NSLog(@"here");
}


-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if([segue.identifier isEqualToString:@"segue1"])
    {
        PhotosTableViewController *photosTVC = segue.destinationViewController;
        photosTVC.photoList = self.photoList;
    }
}

here is the error report

回答1:

I was able to fix it by running "clean" under the "Product" menu in Xcode, and resetting the contents and settings in the simulator.

回答2:

I had this same problem. In my initializer - (id)initWithCoder:(NSCoder *)aDecoder I was doing self = [super init]; when I should have done self = [super initWithCoder:aDecoder];. When I fixed this everything worked as expected.

I had the same problem and struggled with it for hours. Stackmonster's answer solved my problem (rename the storyboard), but I didn't understand why it solved the problem.

I found that when I changed an item on the storyboard (added a label or changed background colour) it was not reflected in the simulator - I wasn't using the storyboard that I could see in xcode, but an older version of the storyboard. I had to rename the storyboard in the project navigator and also rename it in the info.plist (in supporting files) and my label appeared, and the background colour applied, and the segue worked.

I don't know why the storyboard changes weren't taking effect, but it caused me a huge amount of time to find. I've seen on the blogs that a lot of devs have the same problem.

回答4:

i fixed it! 1. make sure the right storyboard is selected in Xcode(if you rename the storyboard change it in the project summary). then delete the app on the simulator and restart

回答5:

In Interface Builder you need to set the segue identifier to segue1 which is a segue connected to your view controller.

回答6:

I tried everything listed and had no luck. What worked was to create a new segue to a new View, then use that one, run it, then create a segue back to the old view.

回答7:

Had this problem with an unwind segue. Finally realized that I lost my identifier when I replaced a view controller on the storyboard. I re-added it by clicking on the unwind segue in the document outline (sidebar of storyboard), and then in the attributes inspector, add the identifier for it.

If nothing else works, at lease in regards to unwind segues, you can call

[self dismissViewControllerAnimated:YES completion:nil];

回答8:

I had the same problem as I made new VC as subclass of another view controller. It should be subclass of UIViewController or UITableViewController. Check header file whether UIKIT is being imported or not.
