1、获取当前设备类型

//0-iPod touch/1-iPhone/2-iPad/3-iPhone Simulator/4-iPad Simulator
+(int)deviceType
{
    NSString *machineType = [[UIDevice currentDevice] model];

    //设备
    if ([machineType compare:@"iPod touch"] == NSOrderedSame)
        return 0;
    else if ([machineType compare:@"iPhone"] == NSOrderedSame)
        return 1;
    else if ([machineType compare:@"iPad"] == NSOrderedSame)
        return 2;

    //模拟器
    else if ([machineType compare:@"iPhone Simulator"] == NSOrderedSame)
        return 3;
    else if ([machineType compare:@"iPad Simulator"] == NSOrderedSame)
        return 4;
    
    //其他类型
    return -1;
}

2、获取当前语言环境

+(NSString*)deviceLanguages
{
    return [[[NSUserDefaults standardUserDefaults] objectForKey:@"AppleLanguages"] objectAtIndex:0];
}

3、获取当前APP版本号

+ (NSString *)projectVerson
{
    NSDictionary *infoDict =[[NSBundle mainBundle] infoDictionary];
    NSString *softVerson =[infoDict objectForKey:@"CFBundleShortVersionString"];

    return softVerson;
}
