How to detect and display device info on iOS - ios

Question

I'm a starter in obj-c programming and I need to know how to display device info ( name, device type, ios version )
I you know the answer, please tell me and keep in mind i'm a starter with xcode ;)

Answer 1

I've used these information in an App that I developed so I did the following code. I think this may help you. I just didn't understand what you mean with device type.
To get the device model:
// get model from UIDevice
NSString *modelDevice = [UIDevice currentDevice].model;
To get the iOS Version:
//get the iOS version
NSString *systemVersion = [[UIDevice currentDevice] systemVersion];
To get the device name:
/** Method responsible to get the device name
*
* #return device Name
*/
+ (NSString *)deviceName
{
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;
}

You may try something like this: I use this for in-app support emailing from users.
#import <sys/utsname.h>
- (void)yourMethod
{
struct utsname systemInfo;
uname(&systemInfo);
NSString *appVersion = [NSBundle mainBundle].infoDictionary[#"CFBundleVersion"];
NSString *osVersion = [[UIDevice currentDevice] systemVersion];
NSString *machine = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
}

NSLog(#"uniqueIdentifier: %#", [[UIDevice currentDevice] uniqueIdentifier]);
NSLog(#"name: %#", [[UIDevice currentDevice] name]);
NSLog(#"systemName: %#", [[UIDevice currentDevice] systemName]);
NSLog(#"systemVersion: %#", [[UIDevice currentDevice] systemVersion]);
NSLog(#"model: %#", [[UIDevice currentDevice] model]);
NSLog(#"localizedModel: %#", [[UIDevice currentDevice] localizedModel])
;

Please refer to UIDevice Class. It has all accessible system information properties. This is a singleton class. You can access this class instance like this : [UIDevice currentDevice]
For example if you want to access device model, you can access like this :
[UIDevice currentDevice]. model
Please refer this link to get information about all properties : https://developer.apple.com/library/ios/documentation/uikit/reference/UIDevice_Class/Reference/UIDevice.html
