iOS获取设备型号、装置类型等信息

iOS获取设备型号、设备类型等信息

设备标识

关于设备标识,历史上盛行过很多英雄,比如UDID、Mac地址、OpenUDID等,然而他们都陆陆续续倒在了苹果的门下。苹果目前提供了2个方法供App获取设备标识:idfa和idfv

idfa:全称advertisingIdentifier,官方解释是广告标识,适用于广告推广,这个建议不要轻易使用,如果用了,则App里必须提供广告功能,否则很有可能会在AppStore审核时被拒。而且idfa是可以被用户关闭的(设置-》隐私),一旦被关闭,就获取不到了。

idfv:全称identifierForVendor,按照字面意思理解,相同的Vendor应该有相同的identifier。Vendor是根据app的bundleid的前两位来界定的,比如对于com.abc.app1和com.abc.app2这2个bundleid的app来说,他们就属于同一个vendor。idfv是一定可以获取到的。需要注意的一点是,当用户将某个vendor下的所有app都卸载掉时,idfv就会被重置,再次安装时,获取到的idfv会跟之前的不一样。所以我用的方案是:idfv+keychain。当然如果用户选择恢复出厂设置,那么还是会出现不一样,这种情况就没法处理了。

 1 +(NSString *)identifier
 2 {
 3     NSString *key = @"com.app.keychain.uuid";
 4     KeychainItemWrapper *keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:key accessGroup:nil];
 5     
 6     NSString *strUUID = [keychainItem objectForKey:(__bridge id)kSecValueData];
 7     
 8     if (strUUID.length <= 0) {
 9         strUUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
10         
11         [keychainItem setObject:@"uuid" forKey:(__bridge id)kSecAttrAccount];
12         [keychainItem setObject:strUUID forKey:(__bridge id)kSecValueData];
13     }
14     
15     return strUUID;
16 }

手机别名

1 +(NSString *)phoneName
2 {
3     return [[UIDevice currentDevice] name];
4 }

手机系统版本

1 /**
2  *  手机系统版本
3  *
4  *  @return e.g. 8.0
5  */
6 +(NSString *)phoneVersion{
7     return [[UIDevice currentDevice] systemVersion];
8 }

手机型号

这个方法只能获取到iPhone、iPad这种信息,无法获取到是iPhone 4、iPhpone5这种具体的型号。

1 /**
2  *  手机型号
3  *
4  *  @return e.g. iPhone
5  */
6 +(NSString *)phoneModel{
7     return [[UIDevice currentDevice] model];
8 }

设备版本

这个代码可以获取到具体的设备版本(已更新到iPhone 6s、iPhone 6s Plus),缺点是:采用的硬编码。具体的对应关系可以参考:https://www.theiphonewiki.com/wiki/Models

这个方法可以通过AppStore的审核,放心用吧。

 1 /**
 2  *  设备版本
 3  *
 4  *  @return e.g. iPhone 5S
 5  */
 6 + (NSString*)deviceVersion
 7 {
 8     // 需要#import "sys/utsname.h"
 9     struct utsname systemInfo;
10     uname(&systemInfo);
11     NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
