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!

Solution 1

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!!!!

Solution 2

put this condition

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

Solution 3

remove extra ")" at the end from this line

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone))

Solution 4

Try this remove last Bracket

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

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) use this line

This question appears to be off-topic because it is about a typo.

This doesn't answer the question which is about the fact that the given code doesn't compile.

this may not the answer of the question, but this answer is the simplest and smartest way to detect screen size my friend.Why should write 3 or 4 lines of code for just detecting the screen size..

-1 for adding a duplicate answer.

[Brad Conidaris]

Which file do I put the code in? Appdelate.m?

[D-eptdeveloper]

@BradConidaris : When you're loading your nib for 3.5 or 4 inch screen you can check this condition and load your nib accordingly

[Brad Conidaris]

Can you elaborate on that? Confused about nibs

[D-eptdeveloper]

@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.
