IOS and tvOS device info

General Information

All methods usage Objective-C code. You could use Objective-C in your application on C++. All you need it just add new class with header *.h and implementation file *.mm. Then add this files to you *.pro using special keywords:

OBJECTIVE_HEADERS += \
    Helpers/Apple/redminedevicehelper.h

OBJECTIVE_SOURCES += \
    Helpers/Apple/redminedevicehelper.mm

Also you need to use frameworks for get access to basic Objective-C classes and methods:

• UIKit

  #import <UIKit/UIKit.h>
  

• Foundation

  #import <Foundation/Foundation.h>
  

In *.pro file you need add this frameworks as a library:

LIBS += -framework Foundation -framework CoreFoundation -framework UIKit

Methods

Device Type

If you need detect your iOS or tvOS device (iPhone, iPad, or Apple TV) in your application you can use code bellow:

BOOL isPhone = ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone);
BOOL isPad = ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad);
BOOL isTV = ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomTV);

Device model name

Name of device:

QString model = QString::fromNSString([[UIDevice currentDevice] model]);

Device OS Version

Name of device OS version (although you should use QOperatingSystemVersion instead of this method):

QString model = QString::fromNSString([[UIDevice currentDevice] systemVersion]);

Device scale factor and retina detection

//Device scale factor
float scale = (float)([UIScreen mainScreen].scale);

//Type of device display
bool isRetina = ([[UIScreen mainScreen] respondsToSelector:@selector(displayLinkWithTarget:selector:)] && ([UIScreen mainScreen].scale == 2.0)) ? true : false;

Device UUID

QString uuid = QString::fromNSString( [[[UIDevice currentDevice] identifierForVendor] UUIDString]);
