Iphone 将浮动转移到其他类？

我有一个问题，我一直在寻找解决方案，但似乎找不到一个可行的。UserInput.xib、Calculations.h和.m、DataOutput.xib。。。没有用于该计算的.xib

这是我的问题。按照我的设置方式，我可以从userInput中携带数据，抛出计算并在DataOutput的标签中显示它们。但是，当 在我在calculations.h中声明的关于calculations.m的if语句中使用浮点数…我不能携带浮点数（实际的数据计算）转到DataOutput屏幕。在DataOutput上，当我试图通过计算将其设置为浮点值时，它无法识别它，它将识别NSString，但不能识别浮点值。我尝试过将浮点值tempResults1转换为NSString results1，但不断出现错误。我尝试了几种不同的方法，从不同的问题和在这里回答，但不明白为什么它不起作用。有人能帮我吗

我想做的是能够在dataoutput屏幕上显示计算结果

我知道它必须是简单的，也许我做错了什么，或者忽略了我没有做的事情……我不知道，我可以使用一些指导，尽管我知道很多。

if（temp1=3）//这没关系
if (temp1 <= 1 && temp2 >= 3) // this is ok
{
  if (temp2 ==10) { // exact floating point comparisons are dangerous,
                    // and should be avoided. you must rewrite this.
                    // turn up your compiler warnings

        tempResults1 = 50;     // this is not what you think it is.
                               // turn up your compiler warnings. you 
                               // are assigning the address for the
                               // pointer's value. this will lead to a
                               // crash after you use it. what exactly
                               // are you trying to accomplish with this
                               // statement? this must be rewritten.
    } 
  else if (temp2 == 11) {tempResults1 = 52;} // as above

{
如果（temp2==10）{//精确浮点比较是危险的，
//应该避免。你必须重写这个。
//打开编译器警告
tempResults1=50；//这不是您所认为的。
//打开你的编译器警告。你可以
//正在为
//指针的值。这将导致
//使用后会崩溃。具体是什么
//你想用这个来完成吗
//声明？这必须重写。

else如果（temp2==11）{tempResults1=52；}//如上所述
