IBAction未知错误[关闭]

Question

    - (IBAction)ButtonPress:(UIButton *)sender {


- (void) ButtonPressed: (id) sender
    {
        if (sender != self.done)
            return;
        if (self.zahlencode.text.length > 0)
        {
            zz =[self.zahlencode.text intValue];
            if(zz == a)
            {

                [self performSegueWithIdentifier:@"1" sender:self];
            }
        }
    }

}

在 Void ButtonPressed 有一个错误提示 Use of undeclared ButtonPressed 如果我在没有应用程序构建崩溃的操作的情况下使用它。我放了一个异常断点，它给出了这个错误

你不能将 void 函数放入 - (IBAction)ButtonPress:(UIButton *)sender 更改如下：

    - (IBAction)ButtonPress:(UIButton *)sender {
       if (sender != self.done)
            return;
        if (self.zahlencode.text.length > 0)
        {
            zz =[self.zahlencode.text intValue];
            if(zz == a)
            {

                [self performSegueWithIdentifier:@"1" sender:self];
            }
         }
}
