I am new to iPhone development i want to make my code compatible with iPhone 4s and iPhone5
but when i apply image to background view of 4S its size 320*480 but it changes in iPhone 5. How to manage this compatibility? Also do i need manage compatibility for buttons and their position in iPhone 4s and iPhone 5. If yes? then how to handle position of button pro-grammatically...

I found this solution ..

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
    // iPhone Classic    }
if(result.height == 568)
{
    // iPhone 5
}}

Does it works?

Yes, you are doing it in correct way.

Now, what you need to do is, you just need check the condition and based on that, you have to set the Frame of the components on the screen.

if([UIScreen mainScreen].bounds.size.height == 568)
{
    // iPhone 5  
     // Set the frame of the buttons for iPhone5 screen
}
else
{
    // iPhone 4
     // Set the frame of the buttons for iPhone4 & 4S screen
}
}

  • Nopes .that do work in Simulator too.But you need to switch your Simulator accordingly. – Ajay Sharma Apr 05 '13 at 18:11

  • you can change your simulator from iOS Simulator-> Hardware->Device-> iPhone (3.5 Retina)/iPhone (4 Retina). similarly with simulator version. – Ajay Sharma Apr 08 '13 at 08:54

  • @user2248322 simply you can use : self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"screen_background.png"]]; or depend on the artwork your image got in background. – Ajay Sharma Apr 08 '13 at 10:02
