在iOS開發中，有時候我們需要使用跟設備相關的一些信息，下面就詳細介紹一下設備相關信息：

1.獲取當前設備所有者名稱：

2.獲取設備的類別，是iPhone，iPod，還是iPad

這裡要獲取iPhone的具體類型，要有如下代碼：

 

- (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.設備本地化類別：

 

 

4.獲取設備的UUID：

 

5.獲取當前手機運行的系統以及當前系統的版本

 

運行效果如下：

 

有時候我們也需要獲取當前App的相關信息，比如當前應用名稱, 當前版本號，用於判斷是否應該提示用戶升級App等.

代碼如下：
