如何在我的mac os x上获取默认浏览器的版本

Question

我希望使用目标C在mac中获取系统信息。我正在搜索很多但没有单行代码供我使用。他们通过javascript提供了解决方案，但我希望它们在目标C中。给我一些帮助继续。

Answer 1

您可以使用启动服务获取默认浏览器的路径，如下所示

LSGetApplicationForURL((CFURLRef)[NSURL URLWithString: @"http:"],
                                kLSRolesAll, NULL, (CFURLRef *)&appURL);

NSString *infoPlistPath = [[appURL path] stringByAppendingPathComponent:@"Contents/info.plist"];

现在从info.plist中读取CFBundleShortVersionString。

Answer 2

干得好 ：

NSString *userName=NSUserName();
NSLog(@"UserName: %@",userName);

NSArray *ipAddress=[[NSHost currentHost] addresses];
NSLog(@"IP Address=%@",ipAddress[0]);

Answer 3

这是经过测试并且运行良好

        NSWorkspace *nsSharedWorkspace = [NSWorkspace sharedWorkspace];
         NSString *nsAppPath = [nsSharedWorkspace fullPathForApplication:appName];
         NSBundle *nsAppBundle = [NSBundle bundleWithPath: nsAppPath];
         NSDictionary *nsAppInfo = [nsAppBundle infoDictionary];

//Now you can print all dictionary to view all its contents and pick which you want
         NSLog(@"%@",nsAppInfo);

//or you can get directly using following methods
         NSLog(@"%@",[nsAppInfo objectForKey:@"CFBundleShortVersionString"]);
         NSLog(@"%@",[nsAppInfo objectForKey:@"CFBundleVersion"]);

别忘了添加AppKit框架
