iOS 设备信息

在iOS开发中，有时候我们需要使用跟设备相关的一些信息，下面就详细介绍一下设备相关信息：

1.获取当前设备所有者名称：

2.获取设备的类别，是iPhone，iPod，还是iPad

这里要获取iPhone的具体类型，要有如下代码：

- (NSString *)deviceString {

    // 需要#import "sys/utsname.h"
    struct utsname systeminfo;
    uname(&systeminfo);

    NSString *deviceString = [NSString stringWithCString:systeminfo.machine encoding:NSUTF8StringEncoding];

    //iPhone
    if ([deviceString isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";
    if ([deviceString isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
    if ([deviceString isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
    if ([deviceString isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
    if ([deviceString isEqualToString:@"iPhone3,2"]) return @"Verizon iPhone 4";
    if ([deviceString isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";

    if ([deviceString isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
    if ([deviceString isEqualToString:@"iPhone5,2"]) return @"iPhone 5";
    if ([deviceString isEqualToString:@"iPhone5,3"]) return @"iPhone 5C";
    if ([deviceString isEqualToString:@"iPhone5,4"]) return @"iPhone 5C";

    if ([deviceString isEqualToString:@"iPhone6,1"]) return @"iPhone 5S";
    if ([deviceString isEqualToString:@"iPhone6,2"]) return @"iPhone 5S";

    if ([deviceString isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";
    if ([deviceString isEqualToString:@"iPhone7,2"]) return @"iPhone 6";

    if ([deviceString isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
    if ([deviceString isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";

    //iPod
    if ([deviceString isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G";
    if ([deviceString isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G";
    if ([deviceString isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G";
    if ([deviceString isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G";
    if ([deviceString isEqualToString:@"iPod5,1"]) return @"iPod Touch 5G";

    return nil;
}

3.设备本地化类别：

4.获取设备的UUID：

5.获取当前手机运行的系统以及当前系统的版本

运行效果如下：

有时候我们也需要获取当前App的相关信息，比如当前应用名称, 当前版本号，用于判断是否应该提示用户升级App等.

代码如下：
