title: Declaring variables in .h file
body: <p>Just wondering if its good programing practice to have a lot of variables declared in the .h file. </p>
  
  <p>I'm writing my first app through which im learning xcode and obj-c.  This ios app has just one xib, one .m and one .h file.  I find my self a lot of times where i have a certain variable that i need to use in different methods/places in the .m file and i just end up declaring it in the .h file which seems like im making the variable global which i dont think is a good idea to have a lot of those.</p>
  
  <p>Is this safe/ok to have a lot of variables declared in .h file or should i approach it in some other way?</p>
  
  <p>Thanks</p>
