iOS获取app应用版本信息&获取设备的基本信息

• 获取手机应用的版本信息
  NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
  NSString *name = [infoDictionary objectForKey:@"CFBundleName"];
  NSString *version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
  NSString *build = [infoDictionary objectForKey:@"CFBundleVersion"];

  NSLog(@"%@，%@,%@,%@",infoDictionary,name,version,build);
  

• 获取设备的基本信息
  通过UIDevice类的对象，可以获取iOS设备如下的信息
  UIDevice的属性：
  @property(nonatomic,readonly,strong) NSString *name; // 设备的名称，如xxx的iPhone6s
  @property(nonatomic,readonly,strong) NSString *model; // 设备的类型，例如.iPhone，iPod touch
  @property(nonatomic,readonly,strong) NSString *localizedModel; // localized version of model
  @property(nonatomic,readonly,strong) NSString *systemVersion; // 操作系统版本号. 如：8.3， 9.2等

  //获取当前设备对象                            
   UIDevice *device = [UIDevice currentDevice];
   NSLog(@"name: %@", device.name);
   NSLog(@"model:%@", device.model);                            
   NSLog(@"localizedModel: %@", device.localizedModel);
   NSLog(@"systemVersion: %@", device.systemVersion);
   //获取设备的UUID   
   NSLog(@"identifierForVendor: %@", device.identifierForVendor.UUIDString);
