Detect iPhone different resolution in iOS - ios

Question

I am using cocos2d in iOS .
I am having a problem detecting the iphone5 resolution(1136*640).
I am using code:
CGRect screenBounds = [[UIScreen mainScreen] bounds];
When we run app on iPhone simulator (4 inch), it gives screenWidth and screnHeight-320,480 respectively.
Can anyone tell me the solution for this?

Answer 1

Write this code in .m file.
#define WIDESCREEN ( fabs( ( double )[ [UIScreen mainScreen ]bounds ].size.height-( double )568 ) < DBL_EPSILON )
Now you can know the screen size like this.
if(WIDESCREEN)
{
NSLog(#"iPhone5 is here");
}
else
{
NSLog(#"iPhone4 is here");
}

Answer 2

you can add checks in your code for iPhone 4inch screens and 3.5 inch screens
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
// iPhone Classic
// set your frames for classic iPhone here
}
if(result.height == 568)
{
// iPhone 5, iPhone 5S, iPhone 5C
// set your frames for 4 inch iPhone here
}

Answer 3

iPhone 5 resolution is 1136*640 only. If you wanna check just Log below Code
the resolution it will give exactly (1136*640)
CGRect screenBounds = [[UIScreen mainScreen] bounds];
CGFloat screenScale = [[UIScreen mainScreen] scale];
CGSize screenSize = CGSizeMake(screenBounds.size.width * screenScale, screenBounds.size.height * screenScale);
NSLog(#"Screen SIze %#",NSStringFromCGSize (screenSize));
#define IS_IPHONE5 ([[UIScreen mainScreen] bounds].size.width >= 568 || [[UIScreen mainScreen] bounds].size.height >= 568)?YES:NO
#define IS_IPHONE4 ([[UIScreen mainScreen] bounds].size.width >= 480 || [[UIScreen mainScreen] bounds].size.height >= 480)?YES:NO
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
if(IS_IPHONE4)
{
// iPhone 4
}
if(IS_IPHONE5)
{
// iPhone 5
}
}
