IBAction未知错误

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上有一个错误，显示Use of undeclared ButtonPressed 如果我在没有动作的情况下使用它，则App构建崩溃。我在那里放了一个Exception Breakpoint，它发出了这个错误

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

    - (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];
            }
         }
}
