iOS 获取设备、应用相关信息

iOS

2017-08-31

有的时候我们需要针对特定的机型或者系统版本做一些特殊的处理,使得我们的程序能够正常的运行,这时就要去判断设备型号、系统版本了,获取这些信息本身并没有什么技术含量,只是比较零碎,因此为了查阅方便,整理了一份代码出来,用的时候直接copy即可。

设备信息

使用 uname 方法可以获取设备的硬件信息,其中就包括型号,我们可以根据型号具体的判断一个设备,比如 iPhone5s 的型号是 ‘iPhone6,2’;

使用的时候需要导入头文件: #import <sys/utsname.h>

1
2
3
4
5
struct utsname systemInfo;

uname(&systemInfo);

NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];

这样获取的型号,不是我们平时叫的设备名称,所以一般都需要一个对应关系,如下:

1
2
3
4
5

7
8

UIDevice 获取设备相关信息

  • 系统版本号
1
2
// 10.3.2
[[UIDevice currentDevice]systemVersion]
  • 系统名称
1
2
// iOS
[[UIDevice currentDevice] systemName]
  • 电池电量
1
2
//模拟器得到的是 -1
[[UIDevicecurrentDevice]batteryLevel]
  • 厂商唯一串号
1
2
3
//226072EA-5C4C-43F9-9E66-6E8ACE31DE49

[[[UIDevice currentDevice] identifierForVendor]UUIDString]
  • 用户名
1
2
///Matt Reach's iPhone
[[UIDevice currentDevice] name]

infoDictionary

App 的版本,应用名称等都记录在 info.plist 里,可以这样获取:

1
2
3
4
5
6
7
8
9
10
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];

// 应用装到设备上之后,显示的名称
[infoDictionary objectForKey:@"CFBundleDisplayName"]

// 应用的版本号 比如:6.8.3
[infoDictionary objectForKey:@"CFBundleShortVersionString"];

// 应用的build号 比如:2778
NSString *appCurVersionNum = [infoDictionary objectForKey:kCFBundleVersionKey];

其实这个里面信息蛮多的,其他的不再一一列举了:
