I am a newbie on iPhone development.

I have declared开发者_如何转开发 a variable on my .m file like this

#define myFloat     60.0f

Now when I try to use this variable like

CGRect myFrame = CGRectMake(0.0f, 0.0f, myFloat, myFloat);

it says myFloat is undeclared!

How do I do that?

thanks.

Try putting the #define in the .h file.
