'Receiver (<ViewController>) has no segue with identifier 'addSegue'
提问by MicahKE
I have a navigation controller that has a segue links between them called "addSegue". When I click on the tableViewcell though the app crashes and I get the error below:
我有一个导航控制器，它们之间有一个名为“addSegue”的 segue 链接。当我点击tableView单元格时，虽然应用程序崩溃了，但出现以下错误：
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<MSAddFriendsViewController: 0x98cc340>) has no segue with identifier 'addSegue'
I don't think that I have any issues with my code. Here is the method in which I have the line showSegueWithIdentifier:
我不认为我的代码有任何问题。这是我有这条线的方法showSegueWithIdentifier：
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSMutableSet *selectedUsers = [NSMutableSet set];
[self.tableView deselectRowAtIndexPath:indexPath animated:NO];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryCheckmark;
PFRelation *friendsRelation = [self.currentUser relationforKey:@"friendsRelation"];
PFUser *user = [self.allUsers objectAtIndex:indexPath.row];
[friendsRelation addObject:user];
[self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
NSLog(@"Error %@ %@", error, [error userInfo]);
} }];
[self performSegueWithIdentifier:@"addSegue" sender:self];
}

I had this same problem and actually my problem was that I was calling
我有同样的问题，实际上我的问题是我打电话
WRONG: [self.navigationController performSegueWithIdentifier:@"ShowVerify" sender:self];
instead of
代替
CORRECT: [self performSegueWithIdentifier:@"ShowVerify" sender:self];
so check that you are calling correct performSegueWithIdentifier method :)
所以检查你正在调用正确的 performSegueWithIdentifier 方法:)
回答by Anbu.Karthik
use segue identifier in Push Method and give the proper connection
if you are using Identifier, then call this line where u need
如果您正在使用Identifier，则在您需要的地方调用此行
[self performSegueWithIdentifier:@"identifierName" sender:self];
Swift 2.X
斯威夫特 2.X
self.performSegueWithIdentifier("identifierName", sender: self)
Swift 3

self.performSegue(withIdentifier: "identifierName", sender: self)
Regarding the new screen you have added that way. In that screen, when you're finished and want to remove it, it's just:
关于您以这种方式添加的新屏幕。在该屏幕中，当您完成并想要删除它时，它只是：
self.dismiss(animated: false, completion: nil)

Hard to say for sure, but some other people have had similar problems:
很难确定，但其他一些人也有类似的问题：
In this question, the asker instantiated the storyboard with
initinstead ofinstantiateViewControllerWithIdentifierso the segue wasn't set up properly.In this question, it was just something weird going on internally with xcode and the simulator, and running Product->Clean helped.
And of course, it's possible the segue name in the code doesn't match the segue name on the Storybord, but I'm guessing you've checked that a lot of times already!

Check whether UIKIT being or not in header file. I unknowingly made new VC a subclass of View Controller.
检查 UIKIT 是否在头文件中。我不知不觉地将新的 VC 变成了 View Controller 的子类。
