Xcode - How do I Detecting screen size of iPhone

Question

I have two xibs, one for the iPhone 4 and one for the iPhone 5; 3.5 inch and 4 inch. I simply want to put some code that tells the app which to load. I have this code which is supposed to do the job:

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone))
{
    CGSize result = [[UIScreen mainScreen] bounds].size;
    if(result.height == 480)
    {
    //Load 3.5 inch xib
    }
    if(result.height == 568)
    {
        //Load 4 inch xib
    }

I put it in the ViewController.M(is that where I put it?) and the build fails saying there is a parse issue expected identifier of "(" Can anyone help me with this simple fix? Thanks!

`if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)` use this line — Buntylm, Sep 11 '13 at 05:10
This question appears to be off-topic because it is about a typo. — Martin R, Sep 11 '13 at 05:14
the problem is in your code you have added extra ) just remove it it will work — Sugan S, Sep 11 '13 at 05:15
@MartinR Not sure what close reason should be used for that. — Sumurai8, Sep 11 '13 at 05:29
@Sumurai8: There is no "pre-configured" close reason for typo questions (anymore), compare http://meta.stackexchange.com/questions/192846/which-close-reason-should-i-use-to-close-typo-questions-now. — Martin R, Sep 11 '13 at 05:47
Remove `if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)) {`, put the code in viewDidLoad — Maximilian Litteral, Sep 11 '13 at 05:48

add below line in your prefix.pch file...this is the simplest way to check screen size, no need to make extra lines of code...

#define   IsIphone5     ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )

now whereever you want to check screen size , just make condition like below, and you can do whatever you want....

 if(IsIphone5)
{
    //your stuff
}
else
{  
  //your stuff
}

Happy Coding!!!!

This doesn't answer the question which is about the fact that the given code doesn't compile. – rmaddy Sep 11 '13 at 05:14

put this condition

if ((int)[[UIScreen mainScreen] bounds].size.height == 568)
{
    // This is iPhone 5 screen
} else {
    // This is iPhone 4/4s screen
}

@BradConidaris : When you're loading your nib for 3.5 or 4 inch screen you can check this condition and load your nib accordingly – D-eptdeveloper Sep 11 '13 at 05:40
Can you elaborate on that? Confused about nibs – Brad Conidaris Sep 11 '13 at 05:51
@BradConidaris : When you're pushing your viewController with navigation at there you can check for this condition and load the xib file of your requirement. – D-eptdeveloper Sep 11 '13 at 05:57

      CGSize result = [[UIScreen mainScreen] bounds].size;
      if(result.height == 480)

            //Load 3.5 inch xib
      }
      else if(result.height == 568)
       {
