Detect iPhone5, 5s, 6, and 6 plus - ios

Question

Can someone show me how to update the below code to work with iPhone 5, 5s, 6, and 6 +? When I test the simulator for the aforementioned devices, no image is set as the background...
UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:_Image];
[backgroundImageView setFrame:[[self view] bounds]];
[[self view] addSubview:backgroundImageView];
//I EXCPECTED THIS NEXT LINE OF CODE TO WORK TO SET A SEPARATE BACKGROUND FOR IPAD...
UIImage *Image = [[UIImage alloc]init];
if ([[UIScreen mainScreen] bounds].size.height == 480) {
// iPhone, iPod Touch
Image = [UIImage imageNamed:#"image.png"];
}
if ([[UIScreen mainScreen] bounds].size.height == 568) {
// supposably iPhone 5 but only works for 4
Image = [UIImage imageNamed:#"image.png"];
}
if ([[UIScreen mainScreen] bounds].size.height == 1024) {
// iPad
Image = [UIImage imageNamed:#"image.png"];
}
self.view.backgroundColor = [UIColor colorWithPatternImage:Image];

Answer 1

#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define IS_RETINA ([[UIScreen mainScreen] scale] >= 2.0)
#define SCREEN_WIDTH ([[UIScreen mainScreen] bounds].size.width)
#define SCREEN_HEIGHT ([[UIScreen mainScreen] bounds].size.height)
#define SCREEN_MAX_LENGTH (MAX(SCREEN_WIDTH, SCREEN_HEIGHT))
#define SCREEN_MIN_LENGTH (MIN(SCREEN_WIDTH, SCREEN_HEIGHT))
#define IS_IPHONE_5 (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)
#define IS_IPHONE_6 (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)
#define IS_IPHONE_6P (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)
Then compare in your if statement.
UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:_Image];
[backgroundImageView setFrame:[[self view] bounds]];
[[self view] addSubview:backgroundImageView];
UIImage *Image = [[UIImage alloc]init];
if(IS_IPHONE_5)
{
Image = [UIImage imageNamed:#"image.png"];
}
if(IS_IPHONE_6)
{
Image = [UIImage imageNamed:#"image.png"];
}
if(IS_IPHONE_6P)
{
Image = [UIImage imageNamed:#"image.png"];
}
I don't see why you're doing it this way though.... Is it because your image is becoming distorted based on different devices? Because there are easier and more efficient ways to solve this in IB.
