Mac开发中的一些小技巧(持续更新)

解决NSTextField不水平居中的问题

在NSTableView中去掉右击菜单栏蓝色复选框

创建子类WipeMenuBorderTableView继承于NSTableView，重写方法

- (void)drawContextMenuHighlightForRow:(NSInteger)row {
    // do nothing 
}

获取udid

+(NSString* )GetHardwareUUID
{
    NSString *ret = nil;
    io_service_t platformExpert ;
    platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("IOPlatformExpertDevice")) ;
    
    if (platformExpert) {
        CFTypeRef serialNumberAsCFString ;
        serialNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert, CFSTR("IOPlatformUUID"), kCFAllocatorDefault, 0) ;
        if (serialNumberAsCFString) {
            ret = [(__bridge NSString *)(CFStringRef)serialNumberAsCFString copy];
            CFRelease(serialNumberAsCFString); serialNumberAsCFString = NULL;
        }
        IOObjectRelease(platformExpert); platformExpert = 0;
    }
    return ret;
}

获取系统版本号

+(NSString *)systemVersion{
    if (floor(kCFCoreFoundationVersionNumber) >0x1050) {
        NSOperatingSystemVersion version = [[NSProcessInfo processInfo] operatingSystemVersion];
        return [NSString stringWithFormat:@"%ld.%ld.%ld",version.majorVersion,version.minorVersion,version.patchVersion];
    }
    else
    {
        NSString *versionString;
        NSDictionary * sv = [NSDictionary dictionaryWithContentsOfFile:@"/System/Library/CoreServices/SystemVersion.plist"];
        versionString = [sv objectForKey:@"ProductVersion"];
        return versionString;
    }
}

获取系统序列号

+(NSString * )GetHardwareSerialNumber
{
    NSString * ret = nil;
    io_service_t platformExpert ;
    platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("IOPlatformExpertDevice")) ;
    
    if (platformExpert) {
        CFTypeRef uuidNumberAsCFString ;
        uuidNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert, CFSTR("IOPlatformSerialNumber"), kCFAllocatorDefault, 0) ;
        if (uuidNumberAsCFString)   {
            ret = [(__bridge NSString *)(CFStringRef)uuidNumberAsCFString copy];
            CFRelease(uuidNumberAsCFString); uuidNumberAsCFString = NULL;
        }
        IOObjectRelease(platformExpert); platformExpert = 0;
    }
    
    return ret;
}
