Detecting iPhone 6/6+ screen sizes in point values

Question

Given the newly announced iPhone 6 screen sizes:

iPhone 6: 1334h * 750w @2x (in points: 667h * 375w)
iPhone 6+: 1920 * 1080 @3x (in points: 640h * 360w)

I was wondering if there is code that allows me to detect which screen size the user's device is, so that I could adjust and size UIImages and other materials accordingly with the user's device.

So far, I have been using the following:

- (NSString *) platform{
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithUTF8String:machine];
    free(machine);
    return platform;
}

- (NSString *) platformString{
    NSString *platform = [self platform];
    if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";
    if ([platform isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";
    if ([platform isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";
    if ([platform isEqualToString:@"iPhone3,1"])    return @"iPhone 4";
    if ([platform isEqualToString:@"iPhone3,3"])    return @"Verizon iPhone 4";
    if ([platform isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
    if ([platform isEqualToString:@"iPhone5,1"])    return @"iPhone 5 (GSM)";
    if ([platform isEqualToString:@"iPhone5,2"])    return @"iPhone 5 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPhone5,3"])    return @"iPhone 5c (GSM)";
    if ([platform isEqualToString:@"iPhone5,4"])    return @"iPhone 5c (GSM+CDMA)";
    if ([platform isEqualToString:@"iPhone6,1"])    return @"iPhone 5s (GSM)";
    if ([platform isEqualToString:@"iPhone6,2"])    return @"iPhone 5s (GSM+CDMA)";
    if ([platform isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";
    if ([platform isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";
    if ([platform isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";
    if ([platform isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";
    if ([platform isEqualToString:@"iPod5,1"])      return @"iPod Touch 5G";
    if ([platform isEqualToString:@"iPad1,1"])      return @"iPad";
    if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
    if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
    if ([platform isEqualToString:@"iPad2,4"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,5"])      return @"iPad Mini (WiFi)";
    if ([platform isEqualToString:@"iPad2,6"])      return @"iPad Mini (GSM)";
    if ([platform isEqualToString:@"iPad2,7"])      return @"iPad Mini (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";
    if ([platform isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad3,3"])      return @"iPad 3 (GSM)";
    if ([platform isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
    if ([platform isEqualToString:@"iPad3,5"])      return @"iPad 4 (GSM)";
    if ([platform isEqualToString:@"iPad3,6"])      return @"iPad 4 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad4,1"])      return @"iPad Air (WiFi)";
    if ([platform isEqualToString:@"iPad4,2"])      return @"iPad Air (Cellular)";
    if ([platform isEqualToString:@"iPad4,4"])      return @"iPad mini 2G (WiFi)";
    if ([platform isEqualToString:@"iPad4,5"])      return @"iPad mini 2G (Cellular)";
    if ([platform isEqualToString:@"i386"])         return @"Simulator";
    if ([platform isEqualToString:@"x86_64"])       return @"Simulator";
    return platform;
}

As such, should I assume iPhone7,1 and iPhone7,2 are the iPhone 6 while iPhone7,3 and iPhone7.4 are the pluses? If anyone has more concrete way to tell it'd be great, thanks.!

Answer 1

Here is the updated source code you are using this.

iPhone 6 and iPhone 6 Plus models have been added.

Answer 2

I use the following code to determine what device is running (it's a little bit quick and dirty but it does the trick)

if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ){

    CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
    CGFloat screenWidth = [UIScreen mainScreen].bounds.size.width;
    if( screenHeight < screenWidth ){
        screenHeight = screenWidth;
    }

    if( screenHeight > 480 && screenHeight < 667 ){
        NSLog(@"iPhone 5/5s");
    } else if ( screenHeight > 480 && screenHeight < 736 ){
        NSLog(@"iPhone 6");
    } else if ( screenHeight > 480 ){
        NSLog(@"iPhone 6 Plus");
    } else {
        NSLog(@"iPhone 4/4s");
    }
}

(This only works when iPhone 6 / 6 Plus is enabled by adding the appropriate splash screens)

Answer 3

If you prefer macros here are the ones, that you can use to differentiate between the iPhone models. These are based on the point values.

#define IS_IPHONE_4 (fabs((double)[[UIScreen mainScreen]bounds].size.height - (double)480) < DBL_EPSILON)
#define IS_IPHONE_5 (fabs((double)[[UIScreen mainScreen]bounds].size.height - (double)568) < DBL_EPSILON)
#define IS_IPHONE_6 (fabs((double)[[UIScreen mainScreen]bounds].size.height - (double)667) < DBL_EPSILON)
#define IS_IPHONE_6_PLUS (fabs((double)[[UIScreen mainScreen]bounds].size.height - (double)736) < DBL_EPSILON)

Answer 4

I had to detect the iPhone 6 Plus in an app built with iOS 7. Because nativeScale isn't available on [UIScreen mainScreen] I tried to use [UIScreen mainScreen] scale] but this just returned 2.0. So I came up with this solution to detect the iPhone 6 Plus on iOS 7 (should also work on iOS 8):

-(BOOL)iPhone6Plus{
BOOL isiPhone6Plus = NO;
SEL selector = NSSelectorFromString(@"scale");
if ([[UIScreen mainScreen] respondsToSelector:selector]) {
    NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:
                                [[[UIScreen mainScreen] class] instanceMethodSignatureForSelector:selector]];
    [invocation setSelector:selector];
    [invocation setTarget:[UIScreen mainScreen]];
    [invocation invoke];
    float returnValue;
    [invocation getReturnValue:&returnValue];
    if (returnValue == 3.0) {
        isiPhone6Plus = YES;
    }
    NSLog(@"ScaleFactor %1.2f", returnValue);
}
return isiPhone6Plus;

}

The interesting part of this code is, that if I use NSInvocation the return value of the scale selector will be 3.0. Calling this method directly on iOS 7 returns 2.0.

Answer 5

This is what I use in my app with iOS 8:

window=[[[UIApplication sharedApplication] windows] firstObject];

NSLog(@"screenHeight=%f width=%f",window.frame.size.height,window.frame.size.width);

if (window.frame.size.height == 480) {

        do stuff here... 
    }

Prior to Xcode6 / iOS 8, I used this, but screen bounds does not work properly with the resizable simulator or at least it didn't in the Xcode6 betas...

CGRect screenBounds=[[UIScreen mainScreen] bounds];

if (screenBounds.size.height >= 568) {

do stuff here...

}

Answer 6

to me this works for me

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
    UIStoryboard *storyBoard;

    CGSize result = [[UIScreen mainScreen] bounds].size;
    CGFloat scale = [UIScreen mainScreen].scale;
    result = CGSizeMake(result.width * scale, result.height * scale);

    if(result.height == 1136){
        storyBoard = [UIStoryboard storyboardWithName:@"Main_iPhone_5" bundle:nil];
        UIViewController *initViewController = [storyBoard instantiateInitialViewController];
        [self.window setRootViewController:initViewController];

    } else if(result.height == 1334){
        storyBoard = [UIStoryboard storyboardWithName:@"Main_iPhone_6" bundle:nil];
        UIViewController *initViewController = [storyBoard instantiateInitialViewController];
        [self.window setRootViewController:initViewController];

    } else if(result.height == 2208){
        storyBoard = [UIStoryboard storyboardWithName:@"Main_iPhone_6_plus" bundle:nil];
        UIViewController *initViewController = [storyBoard instantiateInitialViewController];
        [self.window setRootViewController:initViewController];

    } else if(result.height == 960){
        storyBoard = [UIStoryboard storyboardWithName:@"Main_iPhone_4" bundle:nil];
        UIViewController *initViewController = [storyBoard instantiateInitialViewController];
        [self.window setRootViewController:initViewController];

    }

} else {

    UIStoryboard *storyBoard;

    storyBoard = [UIStoryboard storyboardWithName:@"Main_iPad" bundle:nil];
    UIViewController *initViewController = [storyBoard instantiateInitialViewController];
    [self.window setRootViewController:initViewController];

}
