Qt wiki will be updated on October 12th 2023 starting at 11:30 AM (EEST) and the maintenance will last around 2-3 hours. During the maintenance the site will be unavailable.
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 isAppleTV = ([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]);
