iOS 如何获取设备信息

• 1.获取当前的设备的ID

NSString *device = [[UIDevice currentDevice].identifierForVendor UUIDString];

• 2.系统版本

NSString *systemVersion   =   [[UIDevice currentDevice] systemVersion];

• 3.是iphone 还是 ipad

NSString *systemModel = [[UIDevice currentDevice] model];

• 4.获取info-plist

NSDictionary *dic =  [[NSBundle mainBundle] infoDictionary]; 

• 5.获取Bundle identifier

NSString *appName = [dic objectForKey:@"CFBundleIdentifier"];  

• 6.获取Bundle Version

NSString *appVersion = [dic valueForKey:@"CFBundleVersion"];     

• 7、获取 userInfo

NSDictionary *userInfo = [[NSDictionary alloc] initWithObjectsAndKeys:  
    deviceID, @"deviceID",  
    systemVersion, @"systemVersion",  
    systemModel, @"systemModel",  
    appName, @"appName",  
    appVersion, @"appVersion",nil];
