xcode - How to make xib compatible with both iphone 5 and iphone 4 devices

Question

I am trying to layout my xib so that layout fits in both iphone 5 (4 inches retina) and 3.5 devices.

Because I have to support IOS-5 I cannot use autolayout. I have to use springs and Struts.

I tried everything in interface-builder. But either my view is going beyond the bottom of iphone-3.5-inch or not filling completely the iphone-4-inch-retina.

Can someone give a hint how to actually make an xib compatible to both the devices?

For more clarity I am adding screenshots:

When I set size 3.5 in attribute inspector:

it looks in iphone-5. There is a space below the buttons:

If I set size 4 inch in interface builder. You can see that bottom buttons are not visible in iphone-4.

So you will ask what are the settings I am using. Here are they:

Answer 1

1. You add new category for UIviewController and add this code in .h file

    - (id)initWithNibNameforIphone4:(NSString *)nibNameOrNil4 NibNameforIphone5:(NSString *)nibNameOrNil5 NibNameforIpad:(NSString *)nibNameOrNilpad bundle:(NSBundle *)nibBundleOrNil;
   

2. Add this code in your .m file

    - (id)initWithNibNameforIphone4:(NSString *)nibNameOrNil4 NibNameforIphone5:(NSString *)nibNameOrNil5 NibNameforIpad:(NSString *)nibNameOrNilpad bundle:(NSBundle *)nibBundleOrNil
    {
      if (self = [super init])
    {
     self = [self initWithNibName:[self CheckDeviceIphone4:nibNameOrNil4 Iphone5:nibNameOrNil5 Ipad:nibNameOrNilpad] bundle:nibBundleOrNil];
     }
     return self;
   
   }
   
     -(NSString *)CheckDeviceIphone4:(NSString *)iphone4 Iphone5:(NSString *)iphone5 Ipad:(NSString *)ipad {
   
       return ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad) ? ipad :([[UIScreen mainScreen] bounds].size.height == 568) ?  iphone5 :iphone4;
     }
   

3. Open YouProject-Prefix.pch file and import your category here

4. now you just use this in all over project like this

    self.firstView=[[firstView alloc]initWithNibNameforIphone4:@"firstView4" NibNameforIphone5:@"firstView" NibNameforIpad:@"firstViewIpad" bundle:[NSBundle mainBundle]];
