我试图与具有相似来源和不同目的地的segue合作。两个segue都连接了两个UIViewControllers。我想根据选择的任务按下按钮来调用它们。有这个按钮的代码。但是当我运行代码时，它会报告错误＆＃34; SIGABRT＆＃34;。标识符没有错误。
-(void) goTarget
{if (_spaseType==0) {
[self performSegueWithIdentifier:@"fromWelkomeToPlanemetry" sender:self];
}else{
[self performSegueWithIdentifier:@"fromWelcomeToStereometry" sender:self];
}}
