NSInvalidArgumentException - 接收者没有标识符 [英] NSInvalidArgumentException - receiver has no segue with identifier

问题描述

我已经尝试了几个小时，但没有任何效果.我试图在两个视图控制器之间进行切换，从一个 tableViewController 到另一个 tableViewController.segue 连接到顶层视图，而不是 tableviewcell.在 Xcode 中设置的标识符与代码中使用的标识符相同(复制和粘贴).昨晚它运行良好，但现在我似乎无法让它在不崩溃的情况下继续运行.

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.

这里是调用segue的方法

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;
    }
}

这是错误报告

推荐答案

我修好了！1. 确保在 Xcode 中选择了正确的故事板(如果您重命名故事板，请在项目摘要中更改它).然后把模拟器上的app删掉重启

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
