GBDeviceInfo  

Detects the hardware, software and display of the current iOS or Mac OS X device at runtime.

Usage: iOS

Simple usage (examples on iPhone 4S running iOS 6.0):

[GBDeviceInfo deviceDetails].majorModelNumber;                          //Returns: 4
[GBDeviceInfo deviceDetails].majoriOSVersion;                           //Returns: 6
[GBDeviceInfo deviceDetails].model == GBDeviceModeliPhone4S;            //Returns: YES
[GBDeviceInfo deviceDetails].family == GBDeviceFamilyiPad;              //Returns: NO

You can also reuse the returned object (this used to be a c struct in previous versions) to save some typing. First assign the object to some variable:

GBDeviceDetails *deviceDetails = [GBDeviceInfo deviceDetails];

Then get whatever you like from the object:

//Model numbers
NSLog(@"Major model number: %d", deviceDetails.majorModelNumber);       //Major model number: 4
NSLog(@"Minor model number: %d", deviceDetails.minorModelNumber);       //Minor model number: 1

//Specific model
if (deviceDetails.model == GBDeviceModeliPhone4S) {
    NSLog(@"It's a 4S");                                                //It's a 4S
}

//Family of device
if (deviceDetails.family != GBDeviceFamilyiPad) {
    NSLog(@"It's not an iPad");                                         //It's not an iPad
}

//Screen type
if (deviceDetails.display == GBDeviceDisplayiPhone35Inch) {
    NSLog(@"It has an iPhone 3.5 inch display");                        //It has an iPhone 3.5 inch display
}

//iOS Version
if (deviceDetails.majoriOSVersion >= 6) {
    NSLog(@"It's running at least iOS 6");                              //It's running at least iOS 6
}

//Raw systemInfo string
NSLog(@"systemInfo string: %@", deviceDetails.rawSystemInfoString);     //systemInfo string: iPhone4,1

Don't forget to import header.

#import "GBDeviceInfo.h"

Usage: OS X

Simple usage (examples on a Mac Pro with an Ivy Bridge 3770K processor running 10.8.2):

[GBDeviceInfo deviceDetails].majorOSVersion;                            //Returns: 8
[GBDeviceInfo deviceDetails].minorOSVersion;                            //Returns: 2
[GBDeviceInfo deviceDetails].family == GBDeviceFamilyMacPro;            //Returns: YES
[GBDeviceInfo deviceDetails].isMacAppStoreAvailable;                    //Returns: YES
[GBDeviceInfo deviceDetails].isIAPAvailable;                            //Returns: YES

You can also reuse the returned object to save some typing. First assign the object to some variable:

GBDeviceDetails *deviceDetails = [GBDeviceInfo deviceDetails];

Then get whatever you like from the object:

GBDeviceDetails *deviceDetails = [GBDeviceInfo deviceDetails];

//OS X Version
if (deviceDetails.majorOSVersion >= 8) {
    NSLog(@"It's running at least OS X 10.8 (Mountain Lion)");          //It's running at least OS X 10.8 (Mountain Lion)
}
if (deviceDetails.minorOSVersion == 2) {
    NSLog(@"Must be running 10.x.2");                                   //Must be running 10.x.2
}

//App Store stuff
if (deviceDetails.isMacAppStoreAvailable) {
    NSLog(@"App store is available.");                                  //App store is available
}
if (deviceDetails.isIAPAvailable) {
    NSLog(@"...and so are IAPs");                                       //...and so are IAPs
}

//Hardware stuff
NSLog(@"SystemInfo string: %@", deviceDetails.rawSystemInfoString);     //SystemInfo string: MacPro3,1
NSLog(@"Major model number: %d", deviceDetails.majorModelNumber);       //Major model number: 3
NSLog(@"Minor model number: %d", deviceDetails.minorModelNumber);       //Minor model number: 1
NSLog(@"Network name: %@", deviceDetails.nodeName);                     //Network name: MyMac.local
NSLog(@"RAM: %.3f GB", deviceDetails.physicalMemory);                   //RAM: 16.000 GB
NSLog(@"CPU frequency: %.3f GHz", deviceDetails.cpuFrequency);          //CPU frequency: 3.262 GHz
NSLog(@"Number of cores: %d", deviceDetails.numberOfCores);             //Number of cores: 8
NSLog(@"L2 Cache size: %.0f KB", deviceDetails.l2CacheSize);            //L2 Cache size: 256 KB

//Endianness
if (deviceDetails.byteOrder == GBByteOrderLittleEndian) {
    NSLog(@"Our machine is Litte Endian");                              //Our machine is Little Endian
}

//Family of device
if (deviceDetails.family != GBDeviceFamilyMacBookAir) {
    NSLog(@"It's not a Macbook air");                                   //It's not a Macbook air
}

//Screen resolution
if (deviceDetails.screenResolution.width == 1920 && deviceDetails.screenResolution.height == 1200) {
    NSLog(@"It has a resolution of 1920x1200");                         //It has a resolution of 1920x1200
}
