ios - 当我在 Collection View 中单击按钮时，我无法将值传递给下一个 View Controller

Question

我遇到了一个问题。我使用了 Collection View 设置更多按钮。我需要单击按钮并将索引值传递给“NextViewController”。但是当我点击按钮时。下面显示错误消息。

我尝试找出错误所在。但我找不到。

有人可以给我一些提示吗？

非常感谢。

我猜问题出在您的按钮操作方法名称:jumpToNextView 在这一行中:

        [cell.cateBtn addTarget:self action:@selector(jumpToNextView:) forControlEvents:UIControlEventAllEvents];

而是更改选择器中的jumpToDrScheduleList:或更改方法名称。

-(void)jumpToNextView:(UIButton*)sender
{

    [self performSegueWithIdentifier:@"MySegueName" sender:sender];
}
