获取带有objective-c的OSX版本

Question

How would I be able to get the OSX version in objective-c? I would like to avoid using shell commands. Eg "10.5" or "10.4"

Answer 1

NSProcessInfo *pInfo = [NSProcessInfo processInfo];
NSString *version = [pInfo operatingSystemVersionString];

Sorry for the formatting, I'm using my iPad to answer this.

Answer 2

As of 10.10 you can use NSProcessInfo.processInfo.operatingSystemVersion to get a NSOperatingSystemVersion struct.

typedef struct {
    NSInteger majorVersion;
    NSInteger minorVersion;
    NSInteger patchVersion;
} NSOperatingSystemVersion;

There's also a helpful isOperatingSystemAtLeastVersion: method.

NSOperatingSystemVersion minimumSupportedOSVersion = { .majorVersion = 10, .minorVersion = 12, .patchVersion = 0 };
BOOL isSupported = [NSProcessInfo.processInfo isOperatingSystemAtLeastVersion:minimumSupportedOSVersion];

Answer 3

You can parse it in this way to get the format you want:

NSProcessInfo *pinfo = [NSProcessInfo processInfo];

NSArray *myarr = [[pinfo operatingSystemVersionString] componentsSeparatedByString:@" "];
NSString *version = [@"Mac OS X " stringByAppendingString:[myarr objectAtIndex:1]];

This fe will give you Mac OS X 10.6.8

Answer 4

You can use the Gestalt function to access the components of the OS version .

Old-time users of Gestalt may be amazed to find that it is still available in 64-bit.

Answer 5

See this response using NSAppKitVersionNumber in case you're using AppKit in your app as well (and want to run on 10.8+ as Gestalt is now deprecated):

How to know what Mac OS the app is running on?

Answer 6

add this code after #import

#define SYSTEM_VERSION_EQUAL_TO(v)                  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)  

after adding above code please add below code where you want to see your os-version

NSString *systemVersion = [[UIDevice currentDevice] systemVersion];
        NSLog(@"System version :%@",systemVersion);

you can easily get OS-version by above code

Thank you
