ios - iPhone游戏的Objective-c制作关卡

我有一个问题游戏，其中我向用户询问一些问题，具体取决于用户正确回答的速度以及用户所处的级别，我希望用户获得具有进度视图的不同xp /进度。

因此，我有一个名为“ levelInt”的全局变量，该变量保存用户所在级别的值（最大级别为20）。我也有一个标签，上面打印'levelInt'变量，还有一个进度视图，显示您进入更高级别的进度/显示当前级别的进度。我也有一个计时器，从2分钟开始倒数，这取决于您回答此问题的速度，进度视图将获得更多xp /更多进度。我这样设置：


totalSeconds是计时器
levelInt是全局变量，用于保存用户所在级别的值
progressView是进度条，显示剩余的xp，直到下一级别


和代码：

问题是，只要我回答正确，然后20秒，进度视图就只会增加大约.10。我应该执行progressView.progress = progressView.progress +（金额）吗？

最佳答案

第一条或第二条语句将始终验证true，
因此，最后三个if语句将永远不会被验证。
数字不能同时验证false和<= 100。
验证> 100至false的数字始终为> 100。

if ( i > 100 )
{
    // All numbers above 100
}
else if ( i <= 100 )
{
    // All numbers lower than or equal to 100
}
else if ( i > 80 )
{
    // Never reached
}
else if ( i <= 80 )
{
    // Never reached
}
else
{
    // Never reached
}
